Mobile phones are often unable to connect to the Internet (Black Shark 1)

If the mobile phone can't access the Internet, it is recommended to try it according to the following steps:

1. Check whether this will happen to other mobile users around. If so, it may be a local network signal problem.

2. Check whether the "Move Data" switch is turned on. Check the Internet settings of the mobile phone. You can reset the network parameters and restart the operation of the mobile phone. Enter mobile phone settings-mobile network (or dual-card and mobile network)-select the card name that needs to access the Internet, keep the card slot that needs to be used open, click the name of access point (APN)- click the menu button "Reset to default settings" (whether the package includes the traffic charges generated by cmnet access points is subject to the actual package opening).

3. Check whether there is still phone bill in the account and whether the mobile phone status is normal.

4. Replace the mobile phone to test whether the SIM is normal.
