Lenovo a628t mobile phone can't receive short messages, but it can change channels. Why?

If an A628t can't receive SMS, it can be received normally by another mobile phone. Please refer to the following methods:

1. Confirm whether all contact information cannot be received normally. If it is a personal contact, it is suggested to recall whether the blacklist of relevant contacts has been set, or to use some third-party message interception related functional software;

2. It may be caused by insufficient storage space. You can enter the information interface-press the menu button-and set to check whether the short message is stored on the SIM card by default. It is recommended to switch the storage location and lead to the space of the mobile phone. In addition, you can check whether the mobile phone space is enough in the settings.

3. It may be caused by abnormal SMS program settings. You can enter system settings-application management-find Lenovo address book-clear data to improve, and back up SMS, contacts and other information before operation to avoid data loss;

4. Back up the fuselage data and restore the factory settings (ps: remember to back up the data before operation to avoid personal data loss), and observe whether there is improvement. If it doesn't work after recovery, you can go to a nearby Lenovo authorized maintenance station for specific detection and treatment.
