SIM Unlock Galaxy S3

This article contains links to resources in relation to SIM-unlocking the Samsung Galaxy S3.

Note that I'm doing this with a second-hand phone so there are no provider contracts involved.

There is software on Android available for unlocking the phone. However, this depends on several variables and may not be successful in each case.

I have not found a method that works!

SIM-unlocking is tightly related to your phone's IMEI. Hence, a very viable option is to pay ~€20 for unlocking at a local phone shop.


To get IMEI, dial *#06# using Phone.
