Unicom's mobile phone always can't receive short messages. What happened?

1. Make sure that your phone is full of memory and can't receive new messages;

2. Check the settings of your mobile terminal to make sure that it has not been intercepted by third-party software such as mobile phone housekeeper and security guards;

3. Check whether the SMS receiving function is turned on;

4. If the verification code is not received and other point-to-point short messages are received normally, you can contact the short message center to check whether there is a sending record, or check whether the other SP sent the corresponding short message at the short message gateway;

When using a mobile phone, it is recommended that:

1: Try to answer the phone in an area with good signal;

2. Reduce call time in areas with poor signal quality;

If you call for a long time, you'd better answer the phone with wired headphones.

In fact, the most important thing is not to call for too long.
