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 been lost or stolen, you must let us know right away so we can protect your account. Just open the Three Pay As You Go app or log in to your account to report it.

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.

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
