Why is there no data connection after the phone is turned on?

If the mobile phone cannot access the Internet through data traffic, it is recommended to take the following steps:

1. Check whether the SIM card has GPRS Internet service or is temporarily closed.

To use the data access function of the mobile phone, the calling card needs to open the data traffic access service. You can contact the local network provider of the calling card to open the online service of data traffic.

2. Check whether the "Move Data" switch is turned on.

Slide your finger down the curtain at the top of the screen and turn the "Move Data" pointer green.

If you still can't access the Internet after the above operations, it is recommended to reset the parameters of mobile Internet access: Settings-Mobile Network-Access Point Name-More-Reset to the default settings.

Please change a calling card.

4. You can also try again in another time period or network environment.

5. Back up mobile phone data (phone book, text messages, pictures, etc. ) and restore the phone to the factory settings.

If the fault still exists, it is recommended to send the mobile phone to the nearest service center for testing and maintenance.
