TalkTalk Mobile PIN and PUK

A PIN is a 4-8 digit code that you’ll need to enter to activate your SIM every time you turn your mobile phone on. It’s not activated by default and you'll need to turn it on and then change it to something more personal to you. Please refer to your Mobile userguide or Manufacturer website for instructions.

What is the default PIN?

The default PIN setting for your new TalkTalk SIM card is 1234.

What if I block my PIN?

If you've entered your PIN incorrectly 3 times in a row, you'll require a PUK to unlock the handset.

PUK stands for Personal Unblocking Key and is a code that is needed to unlock your mobile.

If your mobile asks for a PUK, please Contact us to obtain your PUK code.
