Important Instructions

The codes for Samsung Galaxy S3 T-Mobile models are taken from SAMSUNG database. There are many SAMSUNG databases: North America, South America, Europe, Canada, South America and Australia Asia Pacific. Unlocking codes are assigned to each Samsung Galaxy S3 T-Mobile phone on manufacturing time so each code is specific for each IMEI. Please make sure that on the ordering form you use the IMEI from your Samsung Galaxy S3 T-Mobile - not from its box (sometime are not matching). We do not refund or replace the order if you've submited wrong IMEI. 

We use the Country/Network information to identify the region and the database of your phone so please make sure that you are entering the right country.
