1. - Turn on the handset without any SIM card inside.
2. - Enter your unlock code: #pw+the code+1#
To enter the letter p, press the * (asterisk) key 3 times.
To enter the letter w, press the * (asterisk) key 4 times.
To enter the + sign, press the * (asterisk) key 2 times.
After entereing the last symbol (#), the phone will become unlocked indicating SIM card restriction off and will restart.
No more attempts: Nokia phones usually have three chances to enter the unlock code, if you use these three attempts, the terminal will prompt Not allowed. It does not mean that the code does not work, but that the 3 exhausted. Fixing this is easy; simply click here and re-enter the unlock code.
