Dual sim working on desire

Bought a dual sim adaptor from ebay for 6 quid.20th edition magic sim where you don't cut the sim.working fine...able to access stk menu, but only works if you change network settings to gsm only.will not work on edge or other speeds.but at least it works! Only thing that's a pain is every time I switch sims I have tof keep putting password in for google mail.if you download the app multi sim from market you can set up a little icon for each specific sim number so you know whatnumber is being used.
Might see if I can find adaptor that uses other speeds but not paying silly money.

Hello,
I am very interested in a dual sim adaptor. Can you please post a link to the vendor
P.S Has anybody tried this :
Dual sim card 26th-B 3G dual sim, they claim that it works with 3G also

Great stuff keep us informed, so you don't have to reboot the phone to switch and it fits under the battery?

it is working great with umts. no rebooting. perfect stuff

I really don't know if i feel like cutting!!!! my sim card to pieces
Besides - how will wavesecure act to this changing sim all the time ?
Smirge

Wave secure works fine.you need to add the 2nd number to your safe numbers.I have it installed on my phone.you don't need to reset phone to switch numbers.just click on the sim number you want to be live.
As I stated g works at moment.need to find one that works with hpsda etc.will post link later to one I purchased.
Its the one where you don't need to cut sim so all good.

have just ordered the hpsda compatible sim adaptor today. unfortunately will have to cut sims but not such bad thing- will let you know how i get on

just received my new dual sim adaptor
http://forum.xda-developers.com/sho...em&item=320541527532&ssPageName=STRK:MEWAX:IT
and it rewuires you to cut the sims, very easy as you get a template.
It works- both sims work with Hpsda,3g etc- full internet and the usual fast speeds -unlike the previous adaptor i tried which would ionly allow gprs.
You can switch via the sim tool -which doesnt restart the phone-takes about 12 seconds to switch numbers- works great with wave-secure

Can anyone who has a dual sim working with 3G please confirm, and link to a source. I've tried these before and never had a satisfactory experience. I'd try them again, but want to be sure that they are fully working (for phone and data) before spending even more money on an imperfect solution.
I don't mind cutting SIM's as I have a press tool that does it cleanly - as long as that wont damage current sims. Will my old tool work with current sims? I'm assuming that the footprint and location of the chip hasn't changed in current generation sims?
Also, is it possible to log into one gmail account with one sim, and another with the other sim?

i have just confirmed -see above!
with link also...as advised earlier hpsda works,3g works, everything full internet works.
You have to enter password again for Google market- when you switch. but no other problems.
using both vodafone monthly contracts in the uk.
Also works on my n900 also bonus

-deleted- (didn't see the new page)

I'm certain the answer is no, but I take it this doesn't allow you to recieve calls on both numbers at all times? In other words, the only thing this avoids is having to turn off the phone to swap sims - there are no other advantages?
A long shot really - I get sick of carrying around two phones (One is corporate, the other personal)

yep one phone number at a time..still better than carrying 2 phones though.
No problem with messages either- it seems to save messages from both sims.
not happy about the £36 for unit ,but glad it works

Any one get a dual sim working for desire on 3uk hsdpa speed

i was going to get new mifi unit so i could use my 3uk 5gb monthly mobile broadband allowance
but if my main mobile 3uk sim (500mb internet)and 3uk mobile broadband sim (5gb)works with a dual sim, then obviously save me a few bucks
can somebody verify duals sims with 3uk

First of all thank you for sharing with us your findings.
Now here is the scenario: I have a voice only (as in no data plan) SIM and a data only SIM (from a USB stick). I have tested the data SIM, it works just fine in my Desire with the correct APN settings, of course I can't make any calls with it.
Question: would it be possible to use a Dual-SIM adapter so that calls are made from one card and data (APN settings) are from the other SIM? I mean use them SIMULTANEOUSLY without switching from one SIM to the other.
P.S. It's more of an "academic" interest for me as I do have a data plan but since data only SIMs are now free on some networks (RDS in Romania) it would be a nice alternative.

nope it would still need to be switched in order to use other sim data. you can only use 1 sim at a time

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+?

3G/4G on SIM 2 hack?

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?

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)

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.

Unlocked N9750 Dual Sim Mobile Network Connection issues with TMobile SIM installed

Hello,
I just purchased an unlocked Note10+ N9750 Dual Sim in Taiwan, and I am currently located in Taiwan. The phone is on the latest SOFTWARE update from September 1st. ...ASI3.
When I put 2 Taiwanese SIM cards in the phone, the mobile internet works flawlessly and is extremely fast (About 200/50 on each network) when selecting SIM1 or SIM2 for mobile internet, with WiFi disabled. I can switch the cards and it works as expected.
The icons usually show 4G+, although it can sometimes slip into 4G for 10-20 seconds or so.
However, when putting my Tmobile SIM card into SIM1 or SIM2 along with a Taiwanese SIM card, and selecting the Taiwanese SIM card for mobile DATA (The goal here is to use the Taiwanese SIM card for data when in Taiwan), the mobile data is extremely slow (Around 2/0.5).
Furthermore, most of the time, when trying to access the internet, it appears that the phone is trying to connect for the first 5-10 seconds before actually bringing back internet data.
This can be with an app, like Whatsapp, or a simple Google search, or a speed test.
The icons will show 4G+ or 4G, not sure there is a pattern here.
I have tried everything I could think of with roaming ON/OFF, moving the SIM cards around, etc.
APN for Tmobile is correct and setup for IPV4/6 for normal, and IPV4 for roaming.
Again, if I simply replace the Tmobile SIM card with another Taiwanese provider (2 Taiwanese SIM cards installed), the internet is super fast and instantaneous on either SIM card.
The Tmobile SIM is working as expected in a Note9 TMobile Single SIM.
Not sure if anybody has some insight on what may be going on here...
Coming from a Note9 and the Tmobile SIM is less than 1 year old if I recall.
Thank you.

I forgot to mention that if I go into the SIM DEVICE MANAGER with both a Taiwanese SIM card and the TMOBILE SIM card installed and disable the TMOBILE SIM, the internet works fast as expected on the Taiwanese SIM.
As soon as I re-enable the TMOBILE SIM card, the internet is slow again and takes 5-10 seconds before bringing data back from a Google search, etc...

That's because if you are overseas with T-Mobile it caps data speeds I believe at 256kpbs.
I'm guessing the order of the Sim somehow maybe coming into play . Also generally second sim position will give you Lower speeds

Hello Joogle,
I should have mentioned that I have the 15GB pass from Tmobile, so 4G speeds while roaming up to 15GB. The speed when on the Tmobile card is very fast, 50/10 or so.
This is not the issue I believe.
Does 2nd position really give slower speeds? I did not know that.

Interestingly, I am in China at the moment and put a Hong Kong SIM card in slot #2 with my TMOBILE SIM in slot#1. Selected sim#2 for data, and everything works great and is always fast.
Not sure what to make out of that.
Preferred Network is set to: LET/TD-SCDMA/UMTS.
A bit confused by all the options of 4G SWITCHER.

Well, I found out that if I put my TMOBILE SIM in 3G/2G mode only, and leave the Taiwan SIM card at 4G/3G/2G, everything works great and fast with no delay...
This is fine since 3G is good enough for phone calls and text messages.
