What's the matter that Apple's mobile phone can't send text messages?

Hello: 1 Apple mobile phone 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 the number of the SMS center is incorrect, you will not be able to send SMS. The solution is as follows: 2 Call the customer service phone of the local operator, ask the number of the SMS service center, and then set it. 3 For example, for a mobile phone number, first open the dialing page on iPhone, enter * 5005 * 7672 *+8613800WZD00 #, and then click Dial. (Note: WZD indicates the area code of the region, for example, Wenzhou is 0577, so you don't need to add 0 before the area code, just enter 577. The SMS service centers of different operators are different, so it's best to call directly to ask, and the problem of not sending SMS can be solved by setting. 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. Still can't send SMS, please pull out your mobile phone card and insert it again, or try sending SMS with another mobile phone. If you can't send a text message, it may be because the SIM card is broken. Can't send text messages, turn on the iPhone settings to see if the flight mode is turned off because of flying. In addition, Apple's mobile phone can't send text messages, which 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 solved by contacting customer service.
