So i unlocked my US bought s7 edge (AT&T) , they gave me a network unlock code which after entering shows that the device is unlocked but when i insert other providers sim it is not able to search for network and shows no service, is there any way to fix this ? will installing a custom rom fix this issue ?

Hello, so recently I bought a refurbished samsung galaxy s7 (Verizon version) and I live in Europe, Republic of Moldova. So, the phone is unlocked and working global (that says) and I have some problems. When i got the phone it had android 6.0. Everything worked fine, the sim, ussd codes, 3G internet. I didn`t have any verizon crap or apps.
After that, i`ve upgraded to android 7.0 via Odin. I downloaded an official android for verizon s7. Now, with android 7.0, when i open my phone, i get the verizon greeting message (like welcome and verzion logo).
Then, everytime i restart the phone i get the message that my sim is not from verizon wireless. Now, i can`t call any USSD codes (for example *200# that is the code for checking my sim balance). It just shows that it calls the ussd code and then says that the number is incorrect. Also, i can`t connect to the internet. I tried to find the Acces Point Names, but they are nowhere (like this function was deleted).
Also, in my settings app, i have 2 unknown options. T roaming and Service provider Giga LTE, KT twophone service and whenether i enter them, my settings app just crashes and it wants to restart it.
Also... i have a lot of verizon apps..
I tried going to my SIM carrier and they said they dont know how to solve it.
Please help me! Thanks in advice! :3
Hi,
I had updated my S8 device to the newer update G950FXXU1AQJ5 in my device [SM-G950FD]. But after the update, my phone ain't receiving any signal. The phone is detecting sim card and micro SD but ain't getting the mobile network. What to do? I had even flashed firmware again still the problem exists. Please suggest a way to overturn this problem.
P.S.: Sim is of UAE only. Even *#*#4636#*#* is not working.
Hello! I am having the same problem here in Saudi Arabia, it randomly disappears. Did you find a fix?
Try reset apn settings
Hello guys. I am not quite new here, but I never registered (or I did but I couldn't find with which email or username).
However, I am having some trouble with Samsung S7 phone.
First of all, the IMEI on the About page is not the same as the IMEI on the back of the phone.
When I enter the IMEI from the back of the phone in IMEI checker, I get the right phone (Samsung S7).
When I enter the IMEI from the About page in IMEI checker, I get some old BLU phone.
Second problem is that I think this phone is not duos, however, whichever firmware I try to flash, I see the SIM card manager in the Settings. Which is weird to me.
Third problem is that the phone won't connect to network. I've tried 3 SIM cards (all 3 of those works on other phones), but this one just won't connect.
It shows full strength of signal, it also shows the phone number of the SIM, however, when I try to make a call, it says "Not registered on network".
The phone should not be locked as my brother said that he used it for some time, then he updated it to the latest OS and then did a factory reset. After that, the phone just stopped working.
Does anyone know what could be the issue? Why the IMEIs are different?
I am quite sure that the phone model is SM-G930F, however, the model number in Settings shows SM-G930FD. Which is again weird to me.
I've looked on the Google to see a picture of the SIM card slot of Samsung S7 duos and mine SIM card slot does not like that. Also, on one slot, it says only "microSD" and on another "SIM". So, I guess it is not a duos phone.
Any advices?
Thank you in advance!
All the best,
Dale
It sounds like somebody has changed the IMEI of the phone and patched the certificate for the IMEI to work.
Once you reset the phone or update the firmware on it, it will remove the patched certificate allowing the changed IMEI.
You will need to look for someone that does IMEI repair / change to get it working for you again I know there is a guy on the forums here that does them for free. Look through the s7 edge sub forums for them.

Well, I already flashed the firmware multiple times with different basebands and versions of the firmware as I thought that the firmware is wrong. Also tried to flash the firmware with Phone EFS Clear option checked in Odin.
Everything else on the phone works.
Sorry that this isnt help but you not alone, I unbricked a Samsung S7 (SM-G930F) after it suddenly just bricked (hard brick/soft brick - same thing). Eventually when I installed nougat on it, and finally wanted to use the phone, i tried a simcard and noticed how it would load all saved contacts but whatever I dailed, it responded "Not registered to network". Checking the model number it is now SM-G930FD but i am unable to verify the imei becuase of missing box. I tried many firmwares (even those that specify its for SM-G930F) but the model number remains SM-G930FD.
could any help plz be posted...

So guys i have Samsung S7 EDGE SM-G935F it was only on T-Mobile carrier/service, i gave my phone to a friend with different carrier, and he for sure tried something to it to change it so it would acept his sim, and now he returned the phone to me and it doesnt accept my T-Mobile sim, at first when i searched manually networks it was only displaying the other carrier even with my T-Moible sim in, after that i did factory reeset and hard reset, now it shows the T-Mobile network but it says error it cant connect.
Does anyone have idea what could have the guy done to mess up the phone it doesnt acept any sim card now, how can i totally full reset everything do i need to flash custom rom ? Please someone help me i wanna fix it to acept my T-Mobile SIM again like it was from factory.

Check if the imei is available. Do *#06#, if its at 000 maybe it got corrupted
