If you have activated your SIM PIN code and then enter the wrong PIN code into your Lycamobile three times your SIM card will automatically lock. In this case you must enter your PUK code.
Your PUK code is displayed on the SIM card holder that came in your starter pack. Please retain it for safe keeping.
If not please call our Customer Services team on 1300 854 607 and they will be happy to help you.
