Why is the text message not sent?

1. It may be caused by misoperation resulting in the loss of the SMS service center number. Please contact the operator, that is, China Mobile or China Unicom customer service to inquire about the correct service center number, and then change the service center number in SMS-Settings-Service Center Number Correct, restart your phone and try sending text messages.

2. If you still can’t solve the problem, you need to put the mobile phone card into other mobile phones to try. If all the cards are in your mobile phone and you cannot send text messages, please back up the data and download the firmware package upgrade from the official website. Or flash the machine. 3. If the above methods are invalid, you need to go to the customer service center to check the phone.
