Lenovo a750e always receives text messages twice.

1. If it is a service message, it may be the operator's problem. You can consult the operator's customer service for details.

2. If you receive repeated short messages from mobile phone contacts, it may be caused by installing a third-party short message software. It is suggested to try to uninstall related software and observe the usage;

3. It may be caused by too many users accessing the base station near the peak period and the network congestion of operators. Suggest changing the time and environment.

4. It is recommended to replace other SIM cards to see if you can send and receive SMS normally, and it is not excluded that it is caused by the abnormality of your SIM card;

5. It cannot be improved after the above operations. It is recommended to back up the fuselage data and restore the factory settings to see if it can be improved.

If the problem still cannot be effectively solved, it is suggested to take time to go to a nearby Lenovo authorized repair station for specific inspection and treatment.
