Important Instructions

The codes for Samsung Galaxy S3  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  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  - 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.
