Telecom flash message mm did not respond.

If you don't receive a reply when sending a short message by using telecom flash payment, it may be due to the following reasons:

1. Network problem: Please check whether the network connection is normal, and try to resend the SMS or conduct other network activities to determine whether it is a network failure.

2. The other party didn't reply: Although it is unlikely, it is also possible that the other party didn't receive your message or didn't reply in time.

3. SMS service failure: If SMS service fails, there may be no reply after sending SMS. You can try to contact telecom customer service and ask them if they have any questions about SMS service.

4. Mobile phone software problem: Mobile phone software may also affect the sending and receiving of short messages. If you recently installed or updated the mobile phone software, please try uninstalling or rolling back to the old version to see if the problem is solved.

The above are the possible reasons why telecom flash messages don't respond. It is suggested to check the network connection, whether the other party's mobile phone has turned on the ringtone, whether it has received the short message, or contact the other party through other channels to confirm the problem. If it still hasn't been solved, you can consider contacting the telecom customer service and asking if there is a problem with the SMS service.
