Region lock information

If your phone is region locked you need to remove this first. A region lock is activated if you buy a phone in one region (e.g. Europe) and take it to another region (e.g. USA) without first using the original provider for 5 minutes (calling any number). Most new phones with Android 4.3 or higher come with region lock and you can also recognize it from the following sticker on the box of the phone: click here to see sticker image.

To deactivate the region lock enter the code next to 'Extra' from the codes we provided when the phone asks for 'Network Unlock Pin'

Unfreeze instructions

1. put non accepted simcard inside phone
2. start phone
3. (enter pin if set)
4. phone shows 'phone freeze' message
5. (If you have touch screen only model: hit call button)
6. Enter unfreeze code

Important: the digits entered will not be displayed on the phone's screen.
Important 2: On some phones you need to confirm the unfreeze code by hitting '#' button after the last digit of your unfreeze code

Importante note: there is a free method going around doing NV Rebuild using some codes, if you have used this method it is very likely non of the above methods work for you. If you did this talk to support to find a solution. You will need to flash the phone. No refund will be provided in this case.
