Once we've blocked the SIM, we'll send you a new one free of charge. You can also arrange to collect it from your local store.
Activate a new SIM
Your SIM should already be activated, just pop it in and turn the phone on. If it's not working, you’ll need to log in or register via My3. If you’re unable to register via My3, follow the link to the form below.
If you want to activate an eSIM, head over to eSIM support to get started.
