Apple phones can't send text messages. what's up

Usually Apple phones can't send text messages, which may be caused by signal errors, which is very common. If there is no signal, you will not be able to send short messages.

In addition, Apple's mobile phone can't send text messages, or it may be because the phone is used to send messages or advertising text messages, and the number is blocked by the operator. This situation can only be sent to Apple's after-sales repair shop.

If it doesn't work after setting, try to restore the network settings. The network settings are as follows: Open iPhone settings, and then click General, Restore, and Restore Network Settings.
