Why can I make a phone call but not send a message on my Beijing mobile phone number?

It may be because your mobile phone number is in arrears or the SMS function is disabled. You can solve this problem in the following ways:

1. Check whether your mobile phone number is in arrears: If your mobile phone number is in arrears, your SMS function will be disabled. You can log in to Mobile official website or call mobile customer service to check the balance of mobile phone charges and confirm whether you owe money.

2. Check whether the SMS center number is correct: You can check whether your SMS center number is correct first. If it is not correct, your message will not be sent. The number of SMS center is generally +86 13800 100500. You can check the changes in the phone settings.

3. Try to change the SMS application: If your mobile phone can't send SMS, you can try to change the SMS application. Maybe the application is broken, so you can't send text messages.

If you try the above methods, the problem remains unsolved. I suggest you call the mobile customer service phone for consultation, and they will give you a more specific solution.
