Gonna need for details for others to help like what country you are in and network. Did you move the sim card over from another phone or is it a new card?
Where did you buy the device? Are you the original owner or did someone own it before you?

You need to go into the firmware of the phone or call a provider who can walk you through it. There is a way to change it after you update the mobile data. Your almost there its just one more step and then you reset your phone.

To go into the firmware ? Can you detail?
Need your help!!!!!!
When I buy that phone S6 Dues (G920FD) default was 5.0.2 and I can use 3G without any problem. After that there is one oTA update and my 3G has gone. After that I have decided to use Stock ROM but no improvement on mobile data. I have to select GSM for both the SIM and 2G is there with slow connection. Whenever I select WCDMA/GSM for any one of the SIM, immediatley it shows "Emergency calls only" and no mobile data. Wired problem but is there any solution for that? Same IMEI shows in *#06# and back side of S6. But in IMEI.info and mobile info app shows invalid IMEI. Dont know what is the problem.
Try flashing stock 5.1.1 ROM via odin specific for your country.

OK. My first stock rom was from Sammobile and the issue was the same on that. Now I am using |ROM|★ARCADIA v1.0★|►5.1.1 XXU2BOFJ◄|JULY.25.15|★ and issue has no improvement.
After firmware update via odin, my samsung's i9300 IMEI changed and it goes something 004999... everything works fine except calls, it says that is not connected on network. Can anyone help me?

Hi,
Try asking here https://forum.xda-developers.com/galaxy-s3/help where you can get help from the experts.
Good luck.
Hi everybody,
I still have a problem with my carrier signal.
1. Sony XZ SOV34 has SIM unlocked
2. Already unlocked bootloader
3. Using Global ROM and already using ExistenZ Oreo
The problem that makes me confused is imei and baseband, there is no problem, but the sim carrier cannot register.
From this problem what should I do?
Hello can you check your apn settings for your operator? If they are all setup correctly try selecting network manually.
Note: You need to search your own mobile operator's apn settings I can't really help with that.

Fido keys doesn't matter for network connectivity. Since you can't setup APN thats the reason it is not connecting. Are you sure that you are not running dual sim version of Xperia XZ? Can you also try tp flash stock rom without exitenz mods? To see if it changes anything.

Can you try to flash your device with Sony's emma tool and see if it works. If it doesn't fix I don't know what will because this doesn't seem something about software nothing like this happened to anybody I assume.

Thanks sir
Just follow one of these Guides...
If U have Unlock Code for Network:
If not try this. It's not easy but works:
I can't post links here. PM me if you still need help
If your baseband and IMEI has gone just flash the 39.0.C.0.282 AU either with flashtool. Better option is xflasher
