How to activate your Google Pixel 8a
You need to activate your phone before using it for the first time and after a factory reset. To use mobile network services on your phone, you need to insert your SIM into your phone.
If your SIM is locked, key in your SIM PIN and press arrow right. 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. Sign in to the O2 website to get the 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.
