Did you enter the wrong PIN code 3 times? Enter your PUK code to unblock the SIM card of your mobile. Afterwards, you can choose a new PIN code.
There are 3 ways to retrieve your PUK code:
Attention: In some cases you need to be administrator in MyProximus in order to see the PUK code. (Are you administrator or user in MyProximus?)
Don’t confuse the PIN code of your SIM card with the entry code of your mobile. If you forgot the entry code of your mobile, please contact the manufacturer.
Be careful when entering your PUK code.
If you enter the wrong PUK code 10 times, your SIM card will be blocked permanently. In that case you will need to request a new SIM card in a point-of-sale.
