I use Unicom card, but I can't send short messages in Baoshan. What's the matter?

If you are using Unicom number, you can't send SMS for the following reasons:

1. The status of mobile phone number is abnormal (shutdown, cancelled number, etc.);

2. The number of SMS center is wrong;

3. SMS function of mobile phone card is not enabled;

4. Sending a large number of short messages in a short time;

it is suggested to eliminate the above reasons. If you still have questions, you can contact the local Unicom customer service for consultation.
