Getting and activating a replacement SIM
Here's how to order and activate a new SIM, if yours has been lost or stolen.
Report a missing SIM
If your SIM’s lost or stolen, please contact us as soon as possible so we can block it and protect your account.
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 new SIM should already be active – just put it in and switch your device on. If it’s not working, you may need to activate it on My3:
- Log into My3
- Go to More actions
- Tap Activate SIM and follow the on-screen steps
If you want to activate an eSIM, head over to eSIM support to get started.
Other useful information
- We can send your replacement SIM to any address you like. We'll need to take a few details if you're not registered with us already, including your name and email address. Your name will be saved on our system
- You'll need to take photo ID with you if you're collecting a replacement SIM from a Three store
