The mobile phone can't surf the internet, and it can't send short messages to remind you that it needs to be activated.

If the mobile phone uses mobile data to surf the Internet slowly, please solve it as follows:

1. The phone is turned off and restarted.

2. Clear the history and cache of mobile phone surfing: Apply-surf the Internet-click the five-pointed star icon on the screen-History-Menu button-Clear the history.

3. This situation may be caused by a problem with the Internet application, so it is recommended to reset the browser settings. Operation: Applications-Internet-Menu Keys-Settings-Content Settings-Reset Settings.

4. If you are using 3G WCDMA mobile phone, please check whether the network mode is automatic or 3G only. Set the path: Set-(Connect)-More Networks-Mobile Networks-Network Mode-Select Automatic or WCDMA Only Mode. (Note that when 3G only is selected, if there is no 3G signal at the current location, there is no signal in the mobile phone. )

5. If the problem cannot be solved after the above operation, it is recommended that you try to replace another SIM/USIM card.
