Sanitizing Your iPhone

Whether it's your ex girlfriend/boyfriend, your constantly calling network providers, that person you're owing money, "pests", frenemy, a salesperson or someone you just need a digital break from for a bit, Apple lets you limit the communication received from the outside world. If you have people or unknown, annoying numbers that you'd prefer not to see messages or receive phone and Facetime calls from, follow the instructions below.

Phone
If you're in the Phone app under Recents, tap info next to the phone number or contact that you want to block. Scroll to the bottom of your screen, then tap Block this Caller.

FaceTime

If you're in the FaceTime, tap info next to the phone number or contact that you want to block. Scroll to the bottom of your screen, then tap Block this Caller.

Messages

If you're in Messages, open the conversation, tap info, then tap the name or phone number. Scroll to the bottom of the Info screen, then tap Block this Caller.

"Will The Contact Know They're Blocked?"

Short answer is "No". But a perceptive friend might notice that they can never get a hold of you. When someone in your blocked list calls, they will be immediately sent to voicemail. Any message left in voicemail will be put in a separate folder called "Blocked Messages," to which you can listen.

If the contact tries to send you a text or iMessage, from their end, it will look like the message was sent, though you — thanks to your craftiness — will not actually have to see the message.
