This mobile phone is Unicom card. Why do you always send100101reply messages these days?

If you can't get a short message reply, I suggest that you can pass the following conditions:

1, your number is currently in an abnormal state, such as total shutdown and loss reporting;

2. Your mobile phone put the short message in the trash can, so you can check it in the short message trash can first.

3. Due to the large number of users, the speed of sending short messages is slow. I suggest you try again later.

4. There is something wrong with your mobile phone receiving short messages. I suggest you change your mobile phone for the test.

If the above reasons can't solve the problem, I suggest you contact the local manual customer service for handling.
