I can't open the SMS reminder service, saying that my number doesn't support this service. What happened?

If you can't set a traffic reminder for your own number, you can't rule out that it is caused by restrictions. Generally, the following situations will affect business processing:

1. Card cannot handle business when it is in arrears or stops, and cannot handle business by itself when it is blacklisted;

2. You can change your mobile phone to see if you can send SMS command settings normally;

3. If you can send and receive short messages, I suggest you re-insert the card into your mobile phone;

4. Check whether the number of the SMS center is set correctly;

I suggest you check whether there is any problem with your sim card, and take your mobile phone card to the local business hall for testing or replacement.

If the above methods still can't be set up and used normally, it is suggested that you can contact Unicom's manual customer service for verification. The actual situation is subject to local policies.
