What should I do if my zz number for sending text messages has been stopped?

If the zz number for sending text messages has been stopped, you can solve the problem as follows:

1. Re-enable the text message function in "SMS Settings".

2. If the settings are invalid, the problem can usually be solved by restoring the phone to factory settings.

3. If the problem is not solved according to the above method, put the mobile phone card into another mobile phone that can send text messages normally and see if it can send and receive text messages normally. If it can, it means that the problem is caused by the original phone. For that phone, check whether the phone's "SMS Center" settings are correct.

4. If it fails, it means that the mobile phone number card "has been canceled the SMS function". Call the customer service number of the telecom operator corresponding to the mobile phone number, follow the prompts to transfer to manual customer service and report the problem to solve the problem.
