SIM unlock SM-J200M - Samsung Galaxy J2 Questions & Answers

Hello everybody,
A friend of mine asked me to unlock the SIM restriction of her mother's phone.
I tried flashing a stock rom and TWRP. I did it, but still it's SIM locked for a specific network.
What should I do? Is it possible to unlock it by software or I should give it back to her?
Any advice would be greatly appreciated

Im interested too unlock my samsung J2 SM-J200M.
Please guys any way?

Need help unlocking my galaxy s3 !

Hey guys i'm new to this forum but i have been having a very frustrated time i really wanna unlock my FIDO galaxy s3 i know it's not listed here but, i want to unlock to so i can use my rogers sim card can anyone give me any tips how to do this i don't wanna pay for a unlock code
You must be running stock 4.1.1 to use the free unlock method. If you are running 4.3, you will have to buy a code.
If you have to buy a code, you may have to return to stock to enter the unlock code.

[Q] Factory Unlock after Root

Hi all,
I recently completed my contract and received an unlock code for my ATT S3. My phone is currently rooted, but running stock. Will this be a problem when/if I enter the unlock code? I'm looking to move to T-Mobile so any advice is welcome.
Power off the phone, insert a non-ATT sim, boot the phone, enter the unlock code, and you should be fine.
The i747 does not natively support AWS so keep that in mind.

Are you running a stock Samsung ROM? Where did you get the code?
unlock code
From a third party unlock shop who is arguing that they ate sire the code is good
Are you running a stock ROM? Did you check the imei you gave them? Does the imei you get from the dial pad match the imei on the label attached to the back of the phone?

Need help unlocking my Galaxy S3 for AT&T from T-Mobile

So my Galaxy S3 is rooted running AOKP. I have an unlock code from T-Mobile so I can unlock it and use an AT&T SIM card. When I enter the code after booting the device with the AT&T SIM in it, it says unlock unsuccessful.
Do I have to be unrooted & on stock to do this? Or maybe just on stock? Kind of annoying, any help is appreciated!
EDIT: So I figured it out myself. If anyone has this problem in the future, just flash a touchwiz based ROM then reboot and use the unlock code and it should work.

SIM UNLOCK : From Marshmallow to Nougat will affect it or not ?

Hello Experts,
I just wanted to know if going from 6.0.1 to 7.0 will make you lose the Sim Unlock or not ?
If not, when are we exposed to lose our Sim Unlocked phones ?
Thanks in advance

Tried it.
Done.
Flashed stock and custom Roms.
SIM never locked back.
Thanks ?
