> 2.5.6.1 | Description

> This chapter describes how to enter the SIM PUK2. The SIM PUK2 is needed after entering a wrong SIM PIN2 three times to unblock the features that need PIN2 authentication. You have two ways to enter the PUK2. The flow chart gives an example of both ways and shows what happens when entering a wrong PUK2. After entering a wrong PUK2 ten times, all PIN2 dependent features will be blocked. Contact your provider to obtain a new SIM card.
