Automatic blocking with NoCall

The most effective protection is automatic blocking. The NoCall app keeps an updated database with more than 178 spam numbers reported by real users in Spain. After you install the app, those numbers are blocked on your phone automatically — with no manual work.

The database is updated constantly and now holds 1 community reports. Every time someone reports a number, the whole community benefits.

Block a number manually on iPhone

1. Open the Phone app and go to Recents.
2. Tap the information icon (i) next to the number you want to block.
3. Scroll down and choose Block this Caller.
4. Confirm by tapping Block Contact.

To manage blocked numbers: Settings → Phone → Blocked Contacts.

Limitation: iOS only lets you block numbers one by one. That is why we recommend NoCall, which blocks thousands of numbers automatically using the CallKit extension on iOS.

Block a number manually on Android

1. Open Google's Phone app or your manufacturer's dialer.
2. Open Call history.
3. Long-press the number you want to block.

On Samsung: enable protection under Phone → Settings → Caller ID and spam protection.
