Follow these steps to activate your new Pay As You Go on Three SIM card:
If you bought your Three phone and SIM from us you can skip this step. If you're using a non-Three phone, make sure it is 3G and that it's unlocked.
Check that you've fully charged your phone’s battery
Insert your SIM into your phone and switch it on
We'll text you to let you know we've started activating your SIM. Make sure you keep your phone switched on while we connect you to the Three network. This should only take about 30 minutes but during busy periods it make take longer
When we're nearly finished we'll send you another text asking you turn your phone off and on again
Your SIM will now be activated but we’ll send you another text just to confirm.
If you're having any problems activating your SIM call us on 0333 300 3333 (standard rates apply) from any phone (5p per minute from a BT landline, other networks may vary) and we'll get it sorted for you.
