Your caller ID preference determines whether your phone number is visible to people you call. You can choose to hide your number from being displayed on outgoing calls, either on a call-by-call basis or permanently.
Temporary caller ID blocking
- To block on a call-by-call basis: Dial #31# then the number you’re calling
- To unblock on a call-by-call basis (if your number is permanently blocked): Dial *31# then the number you’re calling
Permanent caller ID blocking
Most mobiles have a Show My Caller ID setting which you can turn off. The location of this setting varies depending on your device, but is usually located in Settings > Phone. For more information, please check your device manual.
To check if your mobile number is being displayed to callers:
- Call *#31# then press the Send/Call button
- A message will display on your screen
