How to start Apple SMS?

Enter Settings-Cellular Mobile Network.

Start the cellular mobile network after entering the cellular mobile network. Go back to Settings-drop-down menu to find information and enter it. Enter information, find information settings, send and receive multimedia messages and open them. Return them all, and you can also send text messages and move pictures.

Apple's mobile phone needs to set up its own MMS sending. Otherwise, MMS cannot be sent by default. You can also add pictures directly in the SMS interface and send them by MMS.
