As soon as I played games, the mobile phone network was cut off.

If you disconnect when using mobile data to surf the Internet for no reason, it is suggested that:

1. Check whether the signal is stable. It is recommended to shut down and restart the network, and then try again.

2. Please check whether the mobile data restriction function is set. Mode: Settings-Traffic Monitoring-Setting Traffic Usage Limit-Restricting Traffic Usage-Off (different models of mobile phones may operate in slightly different ways).

3. Please change the other location or try at another time.

4. Try to replace another SIM card.

5. If the mobile data is still disconnected from the Internet for no reason, it is recommended to connect to the wireless network to update the version of the mobile phone system. Note: Please back up the data in the device before upgrading.

6. If it is the latest version, please back up the data (contacts, information, photos, etc. ) and then try to restore the factory settings.

If the problem still exists, please take the purchase invoice, maintenance card and machine to the Samsung service center, and the professional after-sales engineer will help you test it.
