If your Lenovo phone data connection has been turned on, but you can't access the Internet with data data, it is recommended that you restart your phone first.

If you still can't access the Internet, you can choose another access point to switch, go to Settings - Wireless & Network - Mobile Network - Access Point Name, and switch to. If it doesn't work, you can try replacing the number card.

1. Is the mobile data service switch not turned on?

You can scroll down at the top of the screen on your phone to check if the data service is enabled.

Try dialing ** to see if the call works. In addition, if you have just paid the phone bill after the shutdown due to arrears, you need to restart the mobile phone before you can access the Internet normally, please understand. Or you try to change to a different SIM card for testing.
