Most foreign operators block their phones in order to develop loyalty from their customers and tie them to their network as closely as possible. If a SIM card from another operator is inserted into the phone, the phone will require an unlock code, or it will turn on in offline mode. In order to unlock a locked phone, follow a few simple steps.
Instructions
Step 1
Reflash your phone. If the lock is part of the phone's firmware, you can easily get rid of it and be able to use the phone with any SIM card. In order to reflash your phone, use synchronization with your computer. Download a "clean" firmware for this phone model and special software for flashing. Follow the instructions carefully and save the original firmware in case the operation fails.
Step 2
If you own a phone, contact your carrier for an unlock code. Motivate this by the fact that you will need to be on the territory of another country for a long time, and cellular communication is cheaper if you do not use roaming, but connect on the spot. After you are given the unlock code, enter it and use the phone with any SIM card.
Step 3
Contact a specialized phone unlocking service. The fact is that specialized equipment for unlocking costs money, and a lot, and buying it in order to unlock one phone simply does not make sense. Trust the professionals, and after a while you will be free to use your phone on any network.
