Why can't I use SMS reminder?

If you can't handle the traffic SMS reminder function, it doesn't rule out that the number is caused by the following situations:

1 The business type you need to handle is not supported in this channel;

2 Your mobile phone is in an abnormal state, such as arrears, downtime, etc.

3 Some business processing functions are affected during the billing period or at the end of the month. It is suggested that you can handle it after the billing period or contact Unicom's manual customer service.

if it is not the above situation, I suggest you consult Unicom's manual customer service.
