Limited data overseas

I sent my friend an unlocked t999 to use overseas in Taiwan. Using his post paid (Far Eastone) sim card he can only use some data. Voip calls like Tango and Line Naver works. Web and picture messaging does not work. Data messaging apps (whatsapp, cubie, and etc) works kind of weird as text will work but picture messaging will not.
Tried sim card from 2 other Taiwanese carriers on the t999 and data work flawlessly. Requested a new sim card from Far Eastone but same problem. Put the Far Eastone sim card into another friend's unlocked i9300 and data works flawlessly. Finally bought it to the sim card carrier and they mess with few settings on the phone (probably apn settings) and got data working flawlessly. Fast forward to today my friend had to factory reset the phone because of a battery drain issue. Data is once again not working.
I'm trying to understand what the problem is. Why would an unlocked I9300 work right off the bat but an unlocked t999 would not. Very strange as the t999 works with every foreign sim I have tried except this company.

[Q] MMS on SIM 2?

Hello all,
I just got my ZE551ML Zenfone 2 (US) on Friday and have been running it through it's paces. One of the big benefits for me was going to be the dual sim functionality. I was looking forward to using my work SIM in slot one (since it has a big data plan) and my personal SIM in slot 2 (for personal calls, texting, etc.). I have been unable to get my personal sim in slot 2 to send or receive MMS messages, however, which may be a deal breaker. I've tried adding APN's, but they disappear after I hit save. Has anyone managed to get MMS working on SIM 2?

Anything that requires data on the second SIM will not work as it's not supported. In short, no MMS and no internet in SIM 2. Only voice and texts work.

Only SIM card slot 1 can access 3G/4G/LTE data. SIM card slot 2 can only be used for 2G service which include voice and basic text messaging (Not multimedia messaging services MMS or internet browsing).
Sincerely
ASUS_USA

But WHY!? Why no mms option?

It has never been written in any specification of the Zenfone 2 that sim 2 is not data ready.
It is explicitly mentioned 2G including Edge and GRPS...
i.e. 2G does not mean no data but only slow data...
Asus is hiding this information and this is a fault.

Agreed. Asus should explicitly say, "only voice and sms, no mms" -- since many non-tech oriented people don't think of mms as something that uses data. 2G does indeed communicate *very slow* data to people, not, "no data at all, including MMS."

Same issue. It is configure conflict. Reset apn to default then make a new one for your provider and use that one . Delete other one.

Deleting or resetting APNs will not allow mms on sim 2. Sim 2 only supports voice and text.

Yes I agree with u. The mms is looking to sim2 because of apn misconfigure. I use strgth tlk wth att. When I put in att sim it configures apn for att . Apn must be configured for strght tlk to use att. A new apn must be made and used. If u reconfigure att apn an internal mess up seems to occur.

It seems this issue is with phones that are unlocked and the person is installing their own sim provider. All presetup phones from asus don't have this issue

I didn't see they are using 2 sims. Most post of the mms on sim2 issue are a single sim user. Thought this was one of those. Sorry.

SIM2 Not Working

Hi all,
Just got my Zenfone 2 yesterday and was super stoked, however the SIM2 component is not working. I have two SIM cards, one with Telus and one with Virgin Mobile. (Canadian carriers). No matter which order I put them in, the SIM2 card never works. The Zenfone 2 is able to identify the phone number associated with the SIM card in the SIM2 slot, but it is unable to actually make a network connection.
Anyone know how to get SIM2 working?

just update to the latest rom... I did and got my Sim1 working again!!

SIM2 is 2g only. So it needs to be Rogers (or network that uses Rogers) to work

I know this is an old thread but i was wondering if anyone has found a solution to this issue? I am having the same issue trying to get Sim2 to recognize a network. The number on the Sim card is recognized. I have tried switching the cards around and the result is always the same. Both providers that I am with are in Canada. One sim is with Bell and the second is with Virgin Mobile.

Are you saying you can't even make calls on sim2?

A3000 support dual sim?

I was thinking about buy an Oneplus 3 A3000 model. Does anyone know A3000 support dual sim. Does it has 2 separate imei numbers?
Thank you!

Yup, dual SIM and different IMEI numbers for each slot.

You should be able to.

i think it has u choose, u can use sim 1 to make/receive calls/text and sim2 for data, i am not sure if u can have calls on both

You have a primary there is an option to make calls with the secondary if you want.

i have a dual sim setup. i have tried to make a call from sim one. connect to a land line, then from another cell phone call sim two..call on sim 2 goes to voicemail
sim one is my primary number so i set it up to call out from there and make me choose before a call goes out.
when a call comes it, it will tell you sim 1 or 2. you can also label the sim cards now in the latest update.
you can set sim 1 to be data and text, sim 2 can then only do data. one sim card with data at a time.
this works perfect for me since personal phone gets text/calls/data and work line gets only texts and calls.
cool things, textra app can differentiate between sim1 and 2. lets you choose which one to send out from.
i would like it to have different ring tones for each line, but right now i super fine with only carrying ONE awesome phone instead of having to buy another smart phone for work. i would have been carrying around my personal android and then company issued stupid iphone. eeewww, the thought of being a wall hugger with the iphone.
ask me any more questions about dual sim.

i too have a personal and a work phone. dual sim phones are awesome. i currently have a dual s7. i'm thinking about switching to the OP3 because it has 3g on both sim cards and doesn't limit me to 2g on one of the sim cards. my current set up is:
sim 1: 2g - calls and texts (ATT)
sim 2: 2g/3g/4g - calls, text, data (TMO)
it has a sim manager built in so you can switch this at any moment. i can receive calls and text from both sims throughout the day. Is that the case on the OnePlus3?

I am having a problem. I have 2 sims. One for data and one for calls / sms.
I noticed that if the phone just sits there(asleep), calls don't come through. I will get a voicemail notification.
Even tried calling the phone myself. Goes straight to voicemail. If the phone is awake, calls go through no problem.
I have reversed the sims and same problem.
Any ideas. Does doze maybe have anything to do with this?

I do the following,
Sim 1 T-Mobile LTE, text, data, voice
Sim 2 T-Mobile text and voice, turned off data
My settings are sim 1 data, sim 2 text
Calls come in on both lines when ever and how ever. I found that if I didn't set sim 2 to text. Calls and texts didn't work for some reason.
I do have backup data on sim 2 of 2gb.

Any updates on this behavior with latest fw updates? I'm getting a OP3 and will be using dual sim setup. Do I need to get a 3rd party dialer to select which sim to call from, associate certain contacts with certain outgoing calls/sim? I've read about several 3rd party apps for this, but hoping OP3 already has this functionality.

i bought this phone because of dual sim about 3 months before i needed it. Had a second SIM for the last 2.5 months
Well let me tell you, i got the job i was going for, exactly 10 days ago.
It is awesome, i figured out my setting finally. I have it set now for calls to go out to default to SIM1, texts to default of SIM1.
Changed to PROPER network on SIM1, tmobile has a few to choose like fast.tmobile, (e) something or another. i set it to fast.tmobile.
Your dailer will know. you can choose 1 or 2 SIM. Stock, downloaded apps, everything will know. I really like using true caller app now because of this. I now have a potential DOUBLE amount of spam calls!
As with text apps, i like to use textra for one main reason. Delayed text sending. using stock app, i sent MANY texts using the WRONG SIM by accident. I set my delay to 5 seconds.
I set my sim card 1 to be blue, sim card 2 to be red. so the dailer comes up red or blue depending on the sim getting called.
I do wish i can get different ring tones on 2 sim lines. Only custom roms can do that BUT i like to have WORKING bluetooth and Android Auto. So far i have tried Ressurection Remix, both official and the other one floating around. No good when it comes to Android Auto AND working bluetooth. Freedom OS doesnt have different ring tones for dual sims. If you find one that works please let me know!

Question Xiaomi MI11 - dual sim settings - 1 sim for calls 1 for data only

Hi,
I have 2 sims with 2 different phone numbers, but i want the second sim to only be used for Data, and not receive any calls on it. Is there such an option?
Thanks for the help!

If u use the 2nd sim for dat, it has to be switched on, so... Anyone will call it.. Unless you use call blacklisting to block all calls on that sim...

The only options are to block all calls to the data SIM or not to give out the phone number to people. Another option is to find an application that can limit the network on the data SIM to 4G only.
