Important Instructions

* Before ordering makes sure that your phone is asking for the Netowrk Unlocking code when you insert a SIM card of a different carrier.

* Please double-check the IMEI before ordering. Due to ZTE policy we are not able to refund or replace orders if the submitted IMEI was wrong.  Make sure to use the IMEI from your ZTE Grand S3 obtained via Settings->About menu - not from its box as sometime are not matching. Live!
