You may also be able to ask your carrier to turn on permanent caller ID blocking, though there will likely be a fee for doing so.
If you have a Verizon iPhone, you won’t be able to use your phone’s settings to disable caller ID.
Some carriers don’t support caller ID blocking. If you can’t find the appropriate option inside the Phone app’s settings, consider calling your carrier for more information.
