I get an error message on my phone that says "SIM card locked"
The SIM card on your mobile phone will become locked if you enter an incorrect personal identification number (PIN) three times. You won't be able to use your phone, except for emergency calls.
To unlock it you must reset your PIN by entering your SIM card's unique unlock key (also called a PIN unblocking key or PUK).
To unlock your SIM card:
- Log in to MyBell and retrieve your unlock key.
- Enter the unlock key on your mobile phone.
