Hi!
I am using CM10 and recently bought a T-Mobile USA prepaid card. But every time I use this card, I cannot access my access point. The WiFi settings page says that my AP is not within reach. If I replace the T-Mobile US card with my T-Mobile DE card my wifi works again. O.O
That's strange. Maybe it has something to do with the disabled data roaming option.
But I don't want to enable GSM data roaming just to use WiFi!
Did I miss something?
I'm from Sri Lanka and just bought a Galaxy s4 mini duos from a online seller.
There was a label on the retail box saying this phone works with American SIMs only.
Yet the seller mentioned that the phone will be unlocked.
The phone seems to be unlocked. No questions asked when I turn on the phone with local SIMs,
From the two SIMs the one selected to WCDMA mode works fine while the other one which has no option but to work in GSM does not get registered in network. I tried manually selecting the network. It shows a list of available GSM networks but fails to register when the required one is selected. On the other hand when I interchange the network modes on the SIMs the former one which worked fine in WCDMA signals, fails to register on GSM network while the latter one which failed to register with GSM mode, registers and works fine in WCDMA mode.
The SIM selected to work in GSM only mode, shows no network or Emergency calls only.
So the summery is phone does not let the SIMs to register with GSM network but allows for WCDMA network of the same operator.
I also checked, GSM reception is good in the area. Tried several other SIMs the result was same.
As the phone only allow one SIM to use WCDMA mode at once, I'm stuck to using only one SIM in a dual sim phone.
I'm thinking to return the phone. But before that would like if anyone here can help me with this issue.
Can it be due to a unlocking problem or should it be a hardware failure?
Thanking you in advance
For those who have it, is it possible on the dual sim version that when one SIM is on LTE voice/data, can SIM 2 have voice on 3G? I have 2 SIMs with the same company but the company doesn't have a 2G network only 3G/4G LTE.

yes in the settings you can assign each sim to do any function exclusively.
SO to confirm, SIM 1 can be on 4G and SIM 2 can be on 3G? Can you take a screen shot of the menu? Thanks

The phone will use whatever the carrier gives you access to. If for whatever reason SIM 1 gets 4G and SIM 2 only gets 3G, then that's what the phone will get. The sim card looks to your phone carrier and signal availability to determine what service is provided to the phone.
If you also want to limit it to only go as high as 3G, I believe there is also an option for that. I have a Dual SIM Z5 with only one SIM atm. So pictures from my phone are going to be useless for you. But the pathway is as follows:
Settings\Dual Sim settings\Sim card for data Traffic.
hope this helps
I have a Note 5 Dual sim and when SIM 1 is 4G, the second one only has 2G as an option. You wouldn't happen to have another SIM you can throw in and see if sim 1 can be 4g and sim 2 can go to 3g? Preferably the second sim would be either Bell or Telus since they have no 2G network. I really appreciate it. Don't want to buy another 900$ phone to find out that it won't work.
Thanks

Unfortunately I don't have another one. The Z5 uses a micro sim and I don't know many people with one. You're likely able to call up Sony's sales line and have them ask a tech who does know for sure though. If you do, please report back with what you find so this might benefit another person in your same situation!
Good luck!
It won't work, I just looked up the user manual:
Selecting mobile networks
Your device supports the use of two different networks at the same time. You can
select from the following network mode combinations when two SIM cards are
inserted in your device:
• One LTE network and one GSM network
• One WCDMA network and one GSM network
• Two GSM networks
For each SIM card, you can set your device to switch automatically between mobile
networks depending on which mobile networks are available where you are. You can
also manually set your device to use a particular mobile network mode for each SIM
card, for example, WCDMA or GSM.
Different status icons are displayed in the status bar depending on the type or mode
of network that you are connected to. Refer to Status icon on page 35 to see what
the different status icons look like.
Thanks for your help. I'm out of luck...

And that is exactly the case.
One sim is 4G/3G and the other only 2G.
If in the mobile network settings you try to switch SIM 2 from GSM to 3G or 4G you get a notification that SIM 1 will switch to GSM and that SIM 2 will be data traffic SIM card.
I have Z5 Premium Dual and if I set SIM 1 as 4G or WCDMA (3G), SIM 2 will be 2G only. If I set SIM 2 to be 4G or WCDMA, SIM 1 will be 2G only.
You can not set to WCDMA for both or 4G for both slots. But you can set to 2G for both slot, only it's useless to you.
The combination for SIM 1 and SIM 2 is:
- 4G preferred and 2G only
- WCDMA preferred and 2G only
- WCDMA only and 2G only
- 2G only and 2G only
- 2G only and WCDMA only
- 2G only and WCDMA prefered
- 2G only and 4G prefered
So if your carrier do noth have 2G, it's better you use as single SIM or find another dual SIM phone that support 3G on both slots.
I add a last detail to this useful discussion:
You can set mobile data both in the 4G SIM or in the 2G SIM, doesn't matter. You can use voice calls on 4G SIM 1 and keep 2G SIM 2 for data and voice.
I have a dual SIM Z5 premium:
The worst bit is not the fact that only one SIM can have 4G at a time, which seems not to be a problem to most people. The real issue is not even the fact that I have 2 4G Sims and changing from one to another takes many seconds, in which it goes into no signal. The real issue is that when you are at a call in the none-internet assigned SIM, the other internet SIM stops working and you lose your internet connection. The only way to maintain your internet connection is in the only case that the phone call is been made by the same SIM that is currently giving the internet. And no, you cannot change in the middle of a call, since changing disables both Sims for to many seconds and the call would be hanged.
Please if any other user has found a way around this, beside connecting to Wi-Fi, please tell
Run Data Service on one Sim

Yes it is possible that you can use LTE and 3G sim in your Sony Z5. Even it is also possible that you can use LTE sim in both sim ports in all Sony Z series phones. But there is one condition that you have to run data access only from one sim. You will be not able to run data service on both sim cards. You can do this by going to settings option and set your one sim card for call/messages and another for data service only. Check Sony Xperia Z5 Manual- guideusermanual.com/product-name-xperia-z5-manual&po=570042&lang=English for details.
I am from India and have two sim cards on my device.
Sim 1 - Jio which only works on the 4g spectrum and calls are over VoLTE.
Sim 2 - Vodafone which can work on 2g/3g/4g. Calls are not over VoLTE.
I have data packs on both the numbers.
In the settings when I switch my data subscription to Sim 2 i.e. Vodafone, the phone immediately enables 4g on Sim 2 thereby disabling Sim 1 because the Sim 1 only works on 4g.
I would have had no problem if the phone could just let me use my Vodafone Data on 3g but no, it forces the it to use it on 4g and therefore if I want to use data on my Sim 2 I can no longer user Sim 1.
Is there a work-around for this issue?
I am a Canadian who had a working Canadian phone plan. I am traveling in South America and I had canceled my Canadian plan and removed my sim card. I have been traveling in airport mode. Yesterday I tried to buy a Colombian prepaid sim card/plan. The phone was unable to scan for networks. The top right icon is greyed out, in settings about phone network mobile network type "unknown". Mobile Network State "disconnected". I have already done a factory reset.
Please suggest solutions.
