    1: Turn on phone with Not Accepted SIM card.

    2: A menu will pop up to Insert the code.

    3: Insert the provided code and press OK

    4: Device is now unlocked.

    To be able to know if your phone (sony xperia st21) is capable for unlocking, you need to check some guidelines:

    1. Turn on the phone without sim card
    2. Type *#*#7378423#*#*
    3. Select Service info
    4. Select SimLock
    5. Check where is X
    6. If X is on NETWORK, SUBSET or PROVIDER and value is more than 0, you can unlock your phone.
    7. If it is 0 unlock by code is NOT possible. The counter is blocked.

    Thanks.
