How do I block unwanted callers?

If you’re experiencing nuisance callers, then take a look at the below features to help block unwanted calls and learn more about how to report a scam caller.


CallSafe is the perfect way to stop nuisance callers. It’s completely free and you can use it to screen and block unwanted calls. Every time you get a call, CallSafe checks to make sure it's someone you want to hear from. The caller is then either:

  • Approved and put straight through to you.

  • Blocked so that your phone doesn't ring.

  • Screened to confirm who they are.

Before you start using CallSafe, please check that you meet our compatibility requirements


Last Caller Barring is another great way to block unwanted callers. You can use it to block the last number that called you or you can enter specific numbers you want to bar, all for free.

Whenever someone tries to call you from a blocked number, they will hear a recorded message and you won't be disturbed by the call. You can block up to 100 different numbers using this feature.

Take a look at our article for more information on setting up and using Last Caller Barring.


We take scam calls very seriously, so if you have been receiving them, please don’t hesitate to report them to us. You can report aggressive and persistent marketing calls, persistent silent or abandoned calls or calls you think could be scams.

Check and report

Last year in the UK, 11 billion pounds was taken by fraudsters. It’s a growing problem and we want to put the scammers out of action.

With Check and Report, we help you take control of your call security. Now you can check who called you, and if it’s a troublesome caller, report them to us and we’ll do the rest.
