forgotten your PIN code?
If you enter the wrong PIN or PIN2 code three times in a row, your SIM card will be automatically blocked. To unblock your SIM, you'll need your PUK (Personal Unblocking Code).
Don't try to guess your PUK code as you risk locking your mobile phone permanently if you input it wrongly 10 times.
Instead, to find your PUK code, you can either:
- go to the help section if you've registered on My Business Account; or
- call us on 0800 700 600 (or +41 800 700 600 if calling from abroad).
