It can be worrying when you lose your phone, or it gets stolen. And the same goes for if you've misplaced your SIM. If any of these have happened to you recently, it's important that you let us know as soon as possible. That way, we can protect your account from any misuse.
You may be liable for any usage that happens on your SIM before a block is placed. Blocking your SIM will stop this. Blacklisting your phone targets the phone's IMEI (International Mobile Equipment Identity), so when someone goes to insert a SIM card to use it, the phone won't be able to connect to a network.
You can block your SIM card and blacklist your handset in just a few minutes with our step-by-step guide:
If you can't log into your account or call our IVR, you can also speak to one of our Live Chat agents. They can help you to block your SIM and blacklist your phone.
Our Live Chat team are available 9am-8pm Monday to Friday and 9am-6pm Saturday, Sunday and bank holidays.
