Apple can't send text messages when changing the phone number.

Apple's mobile phone can't send SMS, which may be because the SMS service center is not set or set incorrectly, which leads to the inability 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. The solution is as follows:

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

Second, for example, a mobile phone number, first open the dialing page on the iPhone, enter * 5005 * 7672 *+8613800WZD00 #, and then click Dial. (Note: WZD is 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.

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

Fourth, I still can't send text messages. Please dial out the mobile phone card and insert it again, or try to send a short message with another mobile phone. If you can't send a text message, it may be because the SIM card is broken.

Fifth, no texting. Turn on the iPhone settings to see if the flight mode is turned off because the flight is turned on.

Sixth, in addition, Apple's mobile phone can't send text messages, or it may be because it uses mobile phones to send messages or advertising text messages, and the number is blocked by operators. This situation can only be solved by contacting customer service.

Matters needing attention

You can't send text messages to check whether your mobile phone is in arrears. Please try to turn it off and restart it after paying the phone bill in time.

The mobile phone is in the blind area of the operator's signal, or the signal of the surrounding mobile phone is blocked, resulting in no information.
