Sim lock

[Noel99]

I cant unlock the SIM on my Galaxy S8 despite having online chat support giving me the code to do this, twice! I am using a different network than my original o2 and have done as they have asked with instructions but i'm still locked out! Any ideas?

Hi, have you tried the PUK code, I locked my sim few months back & used my PUK code to unlock it without any issues.

It's your phone that needs to be unlocked. Ask O2 for the unlock code.

Hi, I did get the unlock code from o2 on 2 occasions and both times it didn't work 😕
