As the title states, I decided to fork out 20$ on an unlock code for my SGH-T999L. The unlock went smoothly, but I can't connect to any networks for some reason, whether I use my inactive AT&T SIM or my active MetroPCS SIM.
When I set my phone to auto-select the network, it tells me that my SIM doesn't support the network it picks. When I search for networks, I get T-Mobile, AT&T and "311660" on both SIM cards, which neither of them will connect to. I'm sure it has nothing to do with APN settings, as those are solely for MMS and Data if I recall correctly.
Any ideas?
Were you using it with metro before the unlock?

I flashed an aosp rom and ended up toggling my network from LTE to 2G and to 3G. Now I cant connect to LTE at all I even RUUed back to stock unrooted and thats didnt fix anything. Is there anything left I can do or any apn settings i can try im lost?
Any suggestions. Sprint wont fix it since its been rooted. I think the LTE sim card is a problem and wont accept a signal from the tower.

Have you tried another sim or that sim in another phone? How about reseating the sim in your phone after a fresh boot. Have you checked in the forum for the rom you installed?

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 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.
I just bought mate 20x Global version EVR-L29
my problem is I am unable to connect to my 4g network
I tried to install apps like settings database editor to force 4G/LTE only for Huawei
but every time I pick LTE only or GSM/WCDMA/LTE or any type of settings my connection to my mobile network stop working
I lose mobile network connection and I am unable to do basic phone calls
The only way for me to make phone calls is when I pick up GSM ONLY
Any suggestions on what is wrong with my phone or what I should do?
I live now in Egypt using Vodafone network . The phone was bought from the USA.
thank you in advance for your help
Have you gone into your network settings and manually changed your apn settings to work with Vodafone? Google search Vodafone Egypt 4G apn settings or call Vodafone to get them. See if what you already have on your phone is the same.

I did the following so far and with no sucess
1-factory reset
2-tried 3 different sim cards with 3 different networks each one with the right APN settings sent to me from network operator.So i have no problem with sim cards for sure.
3-installed an app called settong database editor and changed hardware network preference to "11" an advice given on youtube to enable me to force phone to operate on LTE only
NONE OF THE ABOVE RESOLVED MY PROBLEM
I Still lose connection with network and unable to do phone calls once i pick any settings but "GSM only " for data connection.
I do not know what to do.
What version Android do you have? If it's 10 then you need to install the APN manually.
