3G/4G on SIM 2 hack? - ZenFone 2 Q&A, Help & Troubleshooting

Hey guys,
So as many of us know, 3/4g is not available on SIM 2. However I'm not sure if its a hardware or software restriction. Often, these are disabled via software due to compliance of wireless licensing. Is our SIM 2 hardware or software handicapped for SIM 2? If it is software disabled, can't we enable it unofficially through software just like 4G LTE on the Nexus 4?

The phone has 2 modems, one for each SIM card. For SIM 2 the modem only supports 2G networks with GPRS data, although or phones are limited to voice only for SIM 2.

It's a Hardware limitation

Is it possible to get incoming calls from either SIM card or do we need to enable only one SIM at a time ?
Same question for the ZD551KL (Selfie), I read something like standby dual sim but I don't know if I misunderstood ... Not having the ability to get phone calls from either cards at the same time would loose all the pros for having dual sim ...

You can have two calls at the same time, at least with the ZE551ML.

I do believe the selfie is dual active LTE on both sim's. The zenfone 2 ZE551ML however used subpar hardware and therefor is only LTE on one sim and 2G on sim2 with even data being blocked by software. The Laser is dual standby with LTE on both sim's. The selfie is less money than their supposed "flagship" ZE551ML, you'd be better off with the selfie than you would this model, it has better up to date hardware. 2G is already being shut down, so what Asus sells as a dual sim phone is in essence a single sim. Asus makes no apologies for using subpar outdated hardware and their customer service is horrid, as is their person Khang who represents them online.
Dual Active is able to handle 2 calls on both sims at the same time. Dual Standby is 1 call at a time on each sim.
If you bought the ZE551ML sorry, but you got suckered like I did. If you didn't buy it yet, don't there are plenty of companies out there in the same price range offering up to date hardware. I would love to replace my sim2 modem, but Asus said that is not an option.

2G data (edge etc) may be being shut down, but I haven't heard of gsm being shut down completely. Far too many handsets still out there that can't call on 3G or LTE.

Thanks for your reply. You're not the only one telling that 2G is being shutdown, but from my researches, it should not be shutdown in France before 2021. And I understand, still so many appliances using 2G connections ! And eh, I'm not buying the smartphone of my life, in 2 years I'll buy another one ...
Also, I searched, searched and searched again, cannot find another smartphone with dual sim, 4 Go RAM, 5,5" Full HD display for as little as 249€ ... And also a decent camera for that price ... I also read the audio part was great on this phone!
You're right, the Selfie seems great, would be a good choice for some magic selfies with my little son, but it lacks NFC and quick charge ... Also I read a review where the writer complained about poor audio quality : people called told him his voice wasn't clear ... That makes me a little bit afraid, for 299€ ...
Am I wrong on any concern?

3GPP and GSM have notified all telcom around the world that 2G network (call/EDGE) will shutdown in order for rollingout bandwidth for 4G and above. this WILL be on the year 2017.
guys i work in telco for a living, my old company which i still keep in touch with also confirmed this. i'm in their rival company though but we are good friends.
the reason being it is going to shut down also because of every node in the telecom network is going toward a PS and CS is basically obsoleted.
PS=packet core switch, CS=circuit core switch
at this very moment, all telecom are doing a lot of changes to their core network, most are trying to change the sigtran to a TCP/IP kind. ok enough said these are the facts.

Sooty84, what country are you talking about?
I checked again, in France there is a contract between Orange and Free running until Jan 2018 for 2G/3G (more than 2 years from now on), and plans for 2024 ... New licenses are still renewed for 2G, I don't think carriers would pay for something shutting down in a year ... And there are a lot of M2M devices out there only supporting 2G connexions. I'm pretty sure 2G will survive for some years in France.
Anyways that's not the main subject of this thread.
And I finally ordered a Selfie, because I saw a photography comparison where picture quality was much better on the Selfie than on the ZE551ML. Hope I'll be happy with it !

I'm in Singapore M1, previously i'm with Starhub.
3GPP told us to crease 2G network service by 2017, we are already preparing that. (moving MSC towards packet switching instead of ss7/sigtran link set)
I think you have to check again with your local telco again, the front line guys won't know about this, the sales guy probably won't tell you either.
BTW you stated 2G/3G, in my case i meant 2G only. 3G itself is a packet service and it will be telco fundamental. 2G gonna retire.
as i stated, they are cleaning this out because of limited radio bands,
they are making way for 4G and above to use these 800mhz 900mhz 1800mhz bandwidth. or at least cather extra for the 3G. this depend on what 3GPP want. all we know is to convert to packet switch due to retirement 2G network.
perhaps you wanna check with sorg, he is from chuanghwa telco in taiwan?

Telus TP2 specs and release date

Anyone have a clue when the TP2 worldphone is due for Telus?
Also, will the front camera be included in the phone? I know in the past the vga cam was removed since CDMA did not support the dual use of phone and data at the same time, but the HSPA network under way (probably one of the reasons they are getting CDMA+HSPA antennas in this phone) it would make sens that they keep the front cam since HSPA supports video calls.
thanks.
just officially announced
Looks like the this week/next week predictions may actually be true.
yup, I kinda stopped posting here but there has been a lot going on with news about this. I also saw a forum posting (lost the link) from a telus employee saying that he got the SNAP dummy phones in today (July 14th).
I wonder what the exact specs are for the GSM antenna. Apparently it will have quad-band edge but no news on what bands the HSPA is going to be on (if at all...).
I know this is the snap and not the tp2, but it could give us an idea of what to expect. the full specs were just posted for the snap.
http://www.htcwiki.com/page/Telus+SNAP good news, full quad-band gsm and edge... now we just hope the tp2 will have hspa on top of that.
seems the telus version will also have a 3.5mm jack as well as geotaging automatic when taking pictures and dual band UMTS (900 and 2100) but no news on the telus HSPA bands yet (which is on the 1900 band)
2100 HSPA, no bellus HSPA for us
I have called 4 telus stores this week. 2 didn't know anything about the launch of the tp2? 1 said his manager played with one a short time ago at a conference and it was a sweet phone but had no idea when it would be available. The last store told me they have not mentioned anything about this phone at there meeting this week so she believed it isn't going to be here for a while yet as all new phones are discussed a couple of weeks before arival. In short it appears everyone knows that the tp2 is coming to telus except people who work at telus. Ha

I've just noticed that according to Bestbuy, TELUS HTC TP2 doesn't have GPS antenna ... I don't think we should trust this website
And it seems they've gotten a few things on best buy
they switched the rom and ram sizes
they put the cdma 3G speeds as cpu speed, and no mention of gsm
1000 limit for phone book entires
and the number of display lines is 5
and no mention of the camera in the specifications but it is mentioned in the overview and they mention it has a flash...
got to love product descriptions at times.

I didn't even notice those mistakes ... Anyway, I wish the GPS will be unlocked. It was locked for the Telus touch pro (1)
Well, on the Telus coming soon page they have this for the touch pro2
Available services*
* Email
* TELUS Navigator
* TELUS Portal by Pocket Express®
* TELUS mobile TV™
* Wireless web
So the gps won't be hidden like in some phones. Though I guess if they were really greedy and mean spirited they could make it only visible/available to the Telus navigator, but that seems like it'd be truly excessive.
oh no, what would we ever do? (say the people on the XDA forum; best place to get custom roms )
but ya I agree with hoping its unlocked out of the box. I think that bestbuy employee should be fired. we should demand that the specifications be met lol
I went into telus after work today to see if they had a TP2 in stock or at least tell me when they would have one. The sale girls didn't know anything about the phone but see did search to see if any where in transit, NO and then how many where in warehouse, NONE.
She said that if they got the phone before Telus actually gets it, that it would be the first time Best Buy ever got a phone before the carrier. ( don't know if that is true but it make sense )
Still waiting, I'm hoping this thing comes out in Canada before the firestone comes out in Europe so I won't second guess my choice.
512 RAM'd be smashing, but 288 for rom'd suck
800 and 1900mhz for cpu would be amazing (horrible battery life)
but if you wanted to fire anybody, it should be for the stretched picture of the TP2. It looks SQUARE!!!!!!
And firehound. Don't second guess yourself. There's always something better round the corner. Does the TP2 suit your current needs? That's the issue at hand. Sure, the Cortex A8 and A9 and Tegra phones will be capable of great stuff... but how long before good games taking advantage of those features and that can be properly played on a cell come out? For example, that zombie augmented reality game for a tegra device looks absolutely brilliant but I think it'd only be fun if it was multiplayer in my opinion (I'd feel a right fool wandering around a table by myself or while others watched for any prolonged period of time), and multi-player's gonna take a while. Same with connectors and stuff. After all, how long has it taken HTC to imlement 3.5mm as a standard? And who knows if the Snapdragon chips will have the same driver issues as the current gen (yes, they've been observed to be really snappy, but running the current software, not software trying to truly take advantage of them).
Sorry to be dense ...
Is the Telus TP2 CDMA or GSM ? I've seen conflicting info...
Basically, I'm trying to decide where to purchase a TP2 from ...
I live in the US and I'm an AT&T subscriber, but hate with they did with the 'FUZE" keyboard...and wonder if they will screw up the TP2.
I've seen the T-Mobile version, and I'm not a fan of the color ... but I could live with that.
I'm tempted to get the European version ... but would like to use 3G in the US.
Telus ? It looks fairly untampered with.

Telus is a CDMA World Phone.
The way I see it, it's primarly a CDMA phone with a SIM card that allow you to roam on GSM network.
Now the question is which band will it support. Nothing official yet so it may not support the 850/1900mhz 3G-HSDPA requierd for 3G+ speeds on ATT
Well looook at that.
Specs, price and etc are official!
http://www.telusmobility.com/en/QC/htc_touchpro2_t7379/index.shtml
Notice the UMTS/HSDPA is only 2100mhz. So no luck for 3G/HSDPA on ATT. I believe this would work on T-Mobile network.
3G EVDO Rev A (800/1900 MHz), UMTS/HSPA (2100 MHz), GSM/ EDGE (850/900/1800/1900 MHz)
I'm surprised that they didn't include the Telus 3G bands. Oh well...

T Mobile USA/International One X owners in need of new SIM when...?

Hello all.
It appears we can expect the transition for 3g data on the 1900 MHz PCS band sometime between now and the end of the year as T Mobile is really looking to deploy LTE in 2013.
So, we (T Mo USA customers) all learned the hard way that we needed an older model micro SIM in order to get data on our phone.
Does anyone know if we will need a newer micro SIM (actually-the current micro SIM provided by T Mobile for the One S) to access the 3g data once it has been deployed?
What do you opine? Any insight would be great.
Thanks!
Shouldn't need to. Some places already have the 1900Mhz deployed as test beds and I haven't heard anything about needing a new sim.
All SIMs do nowadays is hold your subscriber number that gets relayed to a tower. That number is then looked up in a database to see if you meet requirements (e.g. are a paying customer, what services you have enabled, etc.).
I have an old SIM from 2007 that I am still using so I it doesn't work I'll let you know
I had no trouble going from a 2G to a 3G device with it if that helps you.
The only thing I'm worried about is if the 1900Mhz will be counted as roaming on AT&T and whether we'll have to pay extra for it.
I'm not getting data. I just got a sim card from tmobile today.
No data for me. Talked to tmobile and they said to talk to HTC.
What should i do?
Ask for an older SIM. The newer SIMs that Tmo has been using haven't worked on One Xs. Try seeing if they have any older miniSIMs and then you can cut it into a microSim.

T Mobile has roaming agreements with AT&T, so I wouldn't worry about that. With regards to 3g on the 1900 MHz PCS band, it actually has nothing to do with roaming agreements via AT&T. T Mobile is actually reframing their network to allow HSPA and HSPA+ via 1900 spectrum opposed to its current structure which only supports 2g data on the same frequency.
According to T Mobile, they are refarming frequencies of their network to modernize their network; pushing 3g traffic to their 1900 MHz frequency allows them to deploy true LTE on their current 3g AWS bands (1700/2100).
My original concern was, how there is clearly an incompatibility with the newer micro SIMs and the international One X, will that incompatibility cause me to have to switch SIMs when 3g is moved over 1900? I'm not savvy enough to understand the issue between T Mo's current micro SIMs and the reasoning behind the incompatibility with the One X. I certainly don't want to miss out on faster HSPA speeds when it does take off in Boston so, I figured I would ask.
Do you have your One X set to GSM or GSM/WCDMA auto? I currently have mine set on the latter.
Thanks!

There is a thread in the General section discussing this.
You should call into a local store and say you need an older micro SIM, specifically ask for a non GBA micro SIM. If your local store does not have one in stock, the rep might be nice enough to email other local reps and call you back (as they did with me) when they receive a response. Hopefully, you wont strike out. If so, you would have to eBay or Amazon your older micro SIM.
I ended up driving about 10 miles from my office to pick one up as none of the T Mobile stores closest to me (6 of them) had them in stock. When I finally got one, I had never been happier getting Edge speeds in my life, lol.
Thanks, man!

No prob! Glad I could help
Status update...
I thought it would be courteous to update all reading this thread on my discoveries.
I've re-visited the T-Mobile store with a copy of the information found on this thread in hands, only to find that the guys working on that store are either unprepared or unwilling to help. They told me that T-Mobile only carries one type of micro sim across all their stores, they indicated they were not willing to do the legwork, very disappointing since I've been T-Mobile's customer for over 10 years.
Sounds like the alternative is to dig this special, older micro sim out of ebay or amazon, or move to another provider.
Any other alternatives?
That stinks!
Please know that I too struck out after calling 3 local stores (all within 3-5 miles). You probably got someone with less experience or perhaps you went during store peak hours. I recommend you call a branch (obviously not that one) and ask for a manager. Let the manager know that you are looking for a specific type of micro SIM, a non GBA kind. Let him or her know that you have struck via customer care and that he is your last resort as the T Mobile store closest to where you live no longer carry that SIM.
Out of all of T Mo stores that I called, only one person had no clue of what I was talking about but did get someone else on the phone for me. They all told me they no longer carried the older micro SIM.
Don't let this experience discourage you. If you want it for free, you have to call around.
Last resort would be eBay, etc.
Good luck bro!
Hey guys, im thinking of getting a One X for t-mobile and I want to know if all full size sims are non GBA. i already have a cut down full size sim so will that work in the One X on edge speeds?
Jelly: That's what I did when I first got my international HOX and it worked fine with EDGE. Please share if you start receiving 4G speeds....
Thanks,
Why dont you guys just wait till tmo announces their new htc one+?

s4 mini duos network problems

Hello,
I appeal to all the users that have samsung galaxy s4 mini duos (i9192) to give me a honest opinion on their experience usage about this issue
I want to buy the phone because i have 2 sims, work and home and need both always on but i've been read that this phone has major problems with network signal such as:
"Poor network performance. I'm forced to restart 4 to 5 times per day to regain the network access. I checked from my service providers, no issues on their part. Dual Sim a failure. Apart from network issues, the design, ram performance are average. I'll recommend not to buy this instrument unless the dual-sim network problem is rectified."
Like this, there are many more in samsung phone forum.
Anyone can give me their opinion?
False. I'm using it without problems with two sims work/private. Signal strength may be lower, but it's not so bad. Device is very fast, in antutu it has more points than 4 core htc one x+ or galaxy s3.
Software is bit buggy, but nothing serious.

Thanks for the quick answer.
Yes, i have read many reviews and all shows very good results. But if you go to http://reviews.in.samsung.com/7463-en_in/GT-I9192ZWAINU/samsung-galaxy-s4-mini-reviews/reviews.htm you will see the very bad opinions.
Seems that the phone in bad coverage areas lost signal and don't regain signal unless you restart the phone or the network. Have you already been in bad coverage areas?
It will regain signal. For example yesterday - I was in underground parking lot and signal was very poor to none, but somehow I've got the incoming call when moving to other spot.
Maybe it's firmware related. I've updated manually to amh2 version through odin. Mine new csc is ser - Russia
Wysłane z mojego GT-I9192
Anyone else that has not experienced this problems?
I would like to know this also, I'm considering buying it solely because of the "Dual Sim" but I keep reading lots of people complaining about the signal issues.
I dont have any problems with my I9192 been in my hands for 2 months by now the network problem you describe it's very rare just couple of times since I've been using it but I've turn on and off airplane mode
for me it's a really good phone

Same problem
I also have the duos version. Once the signal is lost/falls in the dead spot region, it doesn't come back a automatically. Fed up with this.. after buying such a high end phone, restarting all the time to get network! What is the use of fast processor and all stuff if we can't make a phone call with it? And after reading the comments on the below page, it is clear that this is a known issue of the model:
gsmarena.com/samsung_i9190_galaxy_s4_mini-reviews-5375.php
Any solution for this? The handset has turned out to be useless.
I have not had a problem like this with mine, it works perfect. I live in a bad signal area and if I go down stairs in my house the phone will lose the signal , when I go back up stairs the phone always regains the signal with no problems.
I can't fault this phone, it's ten times better than my last one, HTC Desire V

Thanks,
Only the fact that you mentioned you have to do airplane mode 2 times is just severe enough, because in a phone with this price range that's a problem that should NEVER occur, and you can be the lucky guy that just has good coverage signal all of the time.
I came to the conclusion that it happens with much moore models than the ones that not happen.
I'm going to order the phone even with this feedback hoping that i have a flash of luck and my phone doesn't have the problems, because i've been waiting months for a dual sim phone with top performance and this seems to be the ideal phone to me.
I will post my experience here, if anything goes wrong i will try to sell it.

Yes, i totally agree with you.
I don't know how a brand like Samsung brings to the market a phone in this price range with these problems. And worst, dont't give a solution to them. Did you try to contact Samsung or use the warranty with them?
Same Issue with Samsung GT-I9192
Hi All,
I am facing the same issue with my Samsung GT-I9192, which I purchased on 1st Sep.
I am using 2 simcards, one being Vodafone and the other Idea, India region.
Surprisingly the issue is only with Vodafone, where the signal after dropping (very frequently) does not refresh.
In case of Idea simcard, the signal refresh is working fine.
I am not able to understand if the problem is with the service provider, sim card, hardware or the software.
I used my vodafone simcard with Galaxy Core (another dual sim phones), and they seem to work fine,
which gets me all the more confused.
The only difference that I notice is in the Mobile Network Type.
Its EDGE:2 for Vodafone and UMTS:3 for Idea, wonder if this has got anything to do with the network issues.
I did the default available 2 firmware upgrades since purchase, they seem to have worsened the problems.
Let me know if you are facing the same issue, with the same service provider.
Need to keep a close watch on the solution, as it seems to be affecting more people than expected, surprisingly couldn't find any issues a month back during the time of purchase....
Regards,
Varun

I am not able to understand if the problem is with the service provider, sim card, hardware or the software.
I used my vodafone simcard with Galaxy Core (another dual sim phones), and they seem to work fine,
which gets me all the more confused.
The only difference that I notice is in the Mobile Network Type.
Its EDGE:2 for Vodafone and UMTS:3 for Idea, wonder if this has got anything to do with the network issues.
I did the default available 2 firmware upgrades since purchase, they seem to have worsened the problems.
Let me know if you are facing the same issue, with the same service provider.
Need to keep a close watch on the solution, as it seems to be affecting more people than expected, surprisingly couldn't find any issues a month back during the time of purchase....

In my case, it's Vodafone also, but is in Western Europe.
My concern is that i have exactily the same problem in my present phone (Sony Tipo Dual) and it's the main reason (along side the big improve of speed and etc) for buying this phone. At the present, people call to me and they say that phone answers occupied (no network signal) and i look to the phone and it shows top signal strenght. I'm beginning to think that dual sim phones with android have some limitations (maybe antenna limitations).

Hello,
I appeal to all the users that have samsung galaxy s4 mini duos (i9192) to give me a honest opinion on their experience usage about this issue
I want to buy the phone because i have 2 sims, work and home and need both always on but i've been read that this phone has major problems with network signal such as:
"Poor network performance. I'm forced to restart 4 to 5 times per day to regain the network access. I checked from my service providers, no issues on their part. Dual Sim a failure. Apart from network issues, the design, ram performance are average. I'll recommend not to buy this instrument unless the dual-sim network problem is rectified."
Like this, there are many more in samsung phone forum.
Anyone can give me their opinion?

In my case S4 mini network refresh is not working for secondary sim (aircel India) and working fine for primary sim Tata docomo. I buyed this mobile as it has 1.5 gb RAM with dual sim instead of Nexus 4.
ricjps said:
Thanks,
Only the fact that you mentioned you have to do airplane mode 2 times is just severe enough, because in a phone with this price range that's a problem that should NEVER occur, and you can be the lucky guy that just has good coverage signal all of the time.
I came to the conclusion that it happens with much moore models than the ones that not happen.
I'm going to order the phone even with this feedback hoping that i have a flash of luck and my phone doesn't have the problems, because i've been waiting months for a dual sim phone with top performance and this seems to be the ideal phone to me.
I will post my experience here, if anything goes wrong i will try to sell it.

thats true it should never occur, i think its implementation problem, android its not mean to be for dual sim phones the solution for dual sim on android its a samsung workarround, it should not be buggy but has some problems it does not make the phone unusable for me, I don't get coverage all the time, I travel from city to city and get poor coverage all the way so i think its not a big issue since it happen just a few times.

Hi Sriram,
My problem is very similar, Vodafone on either sim slots gives network problems, and Idea on either sim slots works fine. That makes me think that the problem must be hardware / software related to Network type. Its EDGE2 for vodafone and GPRS1 for Idea. What is the network type of your sim cards?
Phone defect.. Not related to Sim card
ricjps said:
Yes, i totally agree with you.
I don't know how a brand like Samsung brings to the market a phone in this price range with these problems. And worst, dont't give a solution to them. Did you try to contact Samsung or use the warranty with them?

I use idea in the first slot and BSNL in the second slot. The trouble occurs with BOTH SIM. Earlier I used idea -Vodafone pair, the problem was still there. I live in am area where all operators have weak/varying coverage. Airtel and aircel have already been reported as showing same problem. All the users are affected with this issue, so it is clear that this has nothing to do with the operator, it is a fault of the phone either hardware or software. I think you have idea Sim working fine only means idea network is better in your area and may not need frequent network cell changeover. (?) And another fact we can see from the reports is, that, almost ALL THE COMPLAINTS have been reported from INDIA where the model released is the duos.
S4 Mini Network issues.
I too have a S4 Mini for less than a month and I am also facing network issues. One thing to notice is that the sim with internet doesn't have issues. Irrespective of which slot it is in. Currently I have Vodafone IN on Sim 1 and Airtel on 2 (with 3G). Airtel works fine and Voda has issues.
I did speak to Samsung care, they were very nice, however the problem wasn't solved, I have been adviced to go to Samsung service center and get the S/w reimaged.
I still haven't done that, however what I did was to reset the phone and while I was browsing on the play store I got a software called "Where is my Signal" by Grey Boy. For some reason I feel it is working fine now. I have not had any issue from last evening, baring one time when I was on a long conf call for around 150 mins today. else it has been working fine and receiving calls on both sims too.
I had used this software to refresh the network once, it has helped me, not sure if this is going to sustain but for now it is good.
If some one else also has this software installed and is finding this to solve the issues kindly post the same on the forum and may be helpful.
Will repost tomorrow again with the status.
BTW I agree to many opinions in this thread that Samsung should have done some testing or atleast after many of these issues coming up needed to provide a patch upgrade.

Will factory reset work?

I had tried three apps of that kind: where is my signal, network booster(marcstealth), and network refresher lite. None of them could overcome the strange problem of this phone though at first they seemed to be working. Another question is, how do we know when to refresh network? If we know the signal is lost, we can restart or do something like that. Then there is one more issue: sometimes it shows good/full signal strength, but when try to make a call, will realize that it was false! I made to run the network booster app run when signal is low, using tasker app -but we are not supposed to live such a life using this celebrated costly handset.
But one thing in your post is of much importance. DID THAT RESET WORK? You haven't said much about that.

Rajesh

The reason for reset was to ensure that none of the softwares I had installed were causing the issue. The reset didn't change much compared to the way it was earlier.
Some observations of when the problem actually happens (again this is my observation and doesn't need to be the same in your case)
> When I am on a long incoming call on the sim which has Internet.
> Noticed that short calls don't impact the network.
> If there is a call drop imm after you receive a call.
I am planning to get the phone firmware re-imaged from the service center however I will need atleast 10 more days to do it as I am currently in a different city and I am not carrying the invoice copy.
BTW Rajesh, did u get any response from the CEOs office?

Sim Card Data Issues -- Data is only supported on SIM CARD #1

Well, this may be common Knowledge to you Dual Sim card veterans. But I have been killing myself and Tech support for the last week trying to get 4G working on both Sims #1 and #2. I guess we would literally need the guts of 2 modern 4G LTE radios in there with all the bands for each Sim slot.
It's relieving and at the same point disappointing that I can't compare data services with the sims inside the phone at the same time. It makes sense now. I was thinking how can this thing have decent battery life if it's running 2 full sims.
Hopefully this will save some folks some hair pulling data only supported on SIM# 1 and voice only on SIM #2.
So far have been testing the following carriers since I have just recently unshackled myself from sprint!
- T.mobile
- Rok Mobile (33.99 unlimited everything if you pre-pay $399 for the yr. But will they be around for a yr???)
- Ting - pay as little or as much as you need...
- Harbor Wireless -- business plans but they support unlimited music streaming via T-mobile.:good:
i thought zenfone2 would be nice for t-mobile + traveling abroad. so the tmobile sim would have to be in sim slot 1 to get the free data (capped at very slow rates, but free and unlimited). then use the local sim in slot 2 for voice (since tmobile doesn't let you call for free with their global roaming). but sim 2 is GSM only right? no 3G/4G, so i wonder how reception will be abroad being 2g only vs 2g+3g.
You mean that if i have on sim1 data and voice and on sim2 only voice there cant work silmultaneously?
yes, you can have data and voice on sim1 and additional voice on sim2. It would be pointless to pay for 2 data sims, but I understand why you would want it. But in this case, its data on sim1.

Hey All,
I got the Zenfone2 yesterday.
I noticed that the mobile data/Cellular data works only on SIM1. I searched and found no option to enable data on SIM2.
Even if we have data services enabled on SIM2 it if no use as they do not work in SIM2.
Will there be any workaround / Fix for this ?
Is it a zenfone 2 design constraint ?
Regards,
Niri
Hi all,
I have notice that only SIM1 is 2G / 3G / 4G, and SIM2 is 2G .
But I don't unterstand why I cannot receive MMS on SIM2 .
This is very boring, and I'm not sure I'll keep this ZenFone2

2G for the Zf2 would be enough for MMS (slowly, with 300k images), but SIM2 can't support a data network. I'm pretty sure it was needed for the same reason Windows Boxes can't handle two different internet connections (one connection gets used, the other ignored).

This is the most disappointing thing I found after getting my phone. I wanted to use SIM 2 as a backup data service when SIM 1 wasn't working. :|
I hope this is a software limitation and either Asus can push an update or we can do something with custom ROMs.
I dont really see the point on having 2 sims for data. Honestly.
I have reported this issue to Asus .
I called Asus support and the support guy told me I need to do a system update and sent me this link in email. This update is valid only for WW SKU, so if you are using something else call your local support.
I'm trying to update, but I'm not sure how to
I think you can told this a dog too ? like most other support, they don't know what user want. This is the normal update site and has nothing to do with data for 2. Sim port.

Well the changelog for the update as seen on ASUS website does have a mention for this.
I can't see anything in changelog, that the have implemented data to Sim 2. Or I have tomatoes on my eyes ?

When I boght my Zenfone 2 it was stated on the site I bought from that sim2 was voice only... I believe this is how it is supposed to be.
Otherwise phone would be bulkier and a cost a heap more...

the main problem is that you can't receive (or send) MMS with SIM2.... only call and sms
All other dual sim allows MMS with both SIM cards
Yes, while its not a major issue for me personally, I'm surprised that my much cheaper old Acer could handle this OK. The second SIM only ran 2G, but that was enough...I'm surprised there's NO data on the second SIM for the Asus.

All other dual SIMS? Not my previous Samsung Duos, nor, as far as I am aware, any of the DUOS range.
It would be nice though.
from my knowledge, dual sim dual active does not have data on 2nd sim slot
and dual sim dual standby, most of this supports data on both sim slots

FD / Dual sim owners - what's it like?

Hey guys, I see some of you have the FD variant - That's dual-sim isn't it?
I'm thinking of getting one, but what is it like to use dual sim as opposed to lugging two phones? Today I'm carrying a Note4 and Note3 with me... Worth springing the extra $$ or stick with a regular F + my old Note 4?
Happy to hear about your experience!
Still waiting for my FD ...
But the experience with my N920CD do not give me another choice than a DUOS system.
You really don't need to carry a second phone with you, all you need is in one system.
With the new Note 7 and the private folder, you can even have the same App installed twice, so you have two Facebook, WhatsApp and whatever with different accounts in one device ...
So you really can split business and private without carrying two devices.
I've had mine a few days and I'm very happy with it. I'm expecting to get a business phone in the near future and I'm hoping that instead I can just use this phone. I don't want to carry 2 phones. I also travel a fair bit and buy local SIMs when I arrive, so this will allow me to continue to receive texts from my regular phone when I'm traveling.
I don't think I'll ever get a single SIM phone again unless someone, somewhere comes up with a truly global phone plan.
I agree, i have the n920cd duos note 5 and its the only way to go. Work sim in one and personal in the other, I just brought the note 7 duos because i could not go back to having two devices. You can set separate notification and ringtones per sim and in use its dead easy (i.e in text message just select which sim to send from) although you can do this and have defaults for calls data etc.
Still 2G only for second SIM?
Does *#2263# (band selection) work in your dialer?
Or *#197328630#? (basic service mode)

Yes.
I.love the idea of the DUOS but it's missing a band for ATT and doesn't have wifi calling or HD Voice, so i have read.

Neither code works.
For what it's worth, both SIMs are capable of using 3G/LTE, but only one at a time can use it, the other is stuck on 2G.
