Iphone can't send SMS.

Reason: Apple phones can't send text messages. It may be that the SMS service center is not set or set incorrectly, which makes it impossible to send SMS. This is very common. If you don't get the correct number of the SMS center, you won't be able to send SMS.

Solution:

1. Call the customer service phone of the local operator, ask the number of the SMS service center, and then set it.

2. If it still doesn't work after setting, please try to restore the network settings, as follows: Open the iPhone settings, click General, Restore and restore the network settings.

3. If you still can't send SMS, please pull out your mobile phone card and insert it again, or try to send SMS with another mobile phone. If you can't send a text message, it may be because the SIM card is broken.

4. Another possibility is to turn on the iPhone settings and see if the flight mode is turned off because of flying.

5. In addition, Apple's mobile phone can't send messages, or it may be because the mobile phone is used to send messages or advertising messages, which leads to the number being blocked by the operator to send messages. This situation can only be solved by contacting customer service.
