How to turn your Samsung Galaxy S20+ 5G on or off

Key in your SIM PIN and press OK. The default SIM PIN is 0000.

If an incorrect SIM PIN is entered three times in a row, your SIM will be blocked. To unblock your SIM, you'll need to key in your PUK. O2’s help guide will tell you how to get your PUK. Please note: If you key in the wrong PUK ten times in a row, your SIM will be blocked permanently. In this case, you need a new SIM from O2.
