I'm sorry for the inconvenience.
Excuse me, do you use Unicom version or mobile version of Le Meng mobile phone?
If you can't connect to the Internet using mobile data, we recommend that you refer to the following troubleshooting steps:
1. Please confirm whether the sim card you are using is within the range supported by your mobile phone.
2. Please check whether the data switch service is turned on and whether Settings-Dual Card Settings-Data Connection is turned on;
Please check whether the arrears have been paid. If the balance is insufficient, please try to make up the arrears to the operator.
4. It is suggested that you replace other mobile phones or compare the usage of other users of the same operator around you. Do not rule out the poor network environment. If it appears in individual areas, it is recommended to change the network environment as much as possible;
5. If it is possible to change other sim cards, it is recommended that you change your sim card for comparison. If individual sim cards can't surf the Internet normally, it is not ruled out that it is a compatibility problem. It is recommended to contact the operator for specific testing and handling.
6. It is recommended to try to switch access points. The path is as follows: "Settings-Mobile Data-Access Point Name", and the option is to switch to a different access point and try to restart;
7. Please verify whether the device has traffic monitoring settings, such as built-in music security, 360 mobile guards and other software settings;
If the above operations cannot be improved, you can connect to the network normally before. It is recommended to back up the fuselage data and restore the factory settings as much as possible. If the problem still exists after recovery, for your normal use in the future, it is recommended that you take time to go to a nearby Lenovo authorized repair station for specific inspection and treatment.
