How to solve the problem of failure in sending QD information?

1, is your "Re-texting" sent to the same person?

When the short message storage area of the receiver is full (the short message storage capacity is different due to different mobile phone models) and the short message platform of the other party is full (30 short messages per person on the mobile phone short message platform MS), sending again will show that the message has failed.

You can try to send it to yourself, and if you can receive it, prove that yours is ok.

2. Try a friend's card and mobile phone. What's the problem?

3. Have you sent thousands of short messages or harassing short messages to others in a short time? In this case, 1860 will automatically turn off your SMS function.
