Whether it's someone annoying you or a spam number harassing you, you can block their calls, messages and FaceTime.
To fight telemarketing or harassment of people you know or not, blocking these contacts and numbers can be lifesaving. Whether it's SMS, phone calls or FaceTime, it's perfectly possible to block a contact. The only imperative is to have a telephone number, which is sometimes complicated for hidden numbers.
Blocking a number can be done from the phone settings, but as much from the "Phone", "Messages" tab as "FaceTime". Blocking a contact from one of these three options will be effective for all three channels.
So, from “Phone”, “Messages” or “FaceTime”, scroll down to see the “Block calls” option and add an identifier to block. Please note that only contacts saved in the address book can be blocked. It will therefore be necessary to register it first before being able to limit its requests.
