Why can't Apple send text messages?

First, the mobile network settings of MMS may not be set, which can be solved by setting up MMS sending and receiving and restarting the mobile phone.

Secondly, stopping or turning off GPRS will also make it impossible to send or receive MMS. You can check the phone bill and GPRS switch status.

First of all, the specific operation of resetting MMS settings is as follows:

1. Enter the settings page, open the cellular mobile network, and then open "Cellular Mobile Data".

2. Return to the settings, click "Information" and turn on "Send and receive MMS".

Secondly, you can try to restart your phone, as shown below:

1. Turn on Airplane Mode in the settings, and then turn it off.

2. Turn the machine on and off again. Press and hold the power button on the right side of the phone, and then turn it on again.
