How to turn off the SMS receiving function of Apple's mobile phone?

Now IMessage has almost become a gathering place for advertisements, because it can be sent directly to our mobile phones without examination, so many small advertising publishers have taken a fancy to this "fat meat" and joined this camp one after another. So if we don't need it, we might as well close it.

Closing method: Settings-Info-Close iMessage Info.

2, open the SMS filtering function

Apple's mobile phone has SMS filtering function, and most people won't notice it. After opening, it will filter out a lot of spam messages, which is very practical.

Opening method: Settings-Info-Open "Filter Unknown Senders"

3. Cancel the mailbox to receive short messages.

If you must use the iMessage function, you can also turn off mail reception in the message, or uncheck mail reception.

Closing method: Settings-Information-Send/Receive-Uncheck the mailbox.
