Why my LG G4 has issues with mobile internet?

[Lorenzo72]

My LG G4 worked very well for 13 months... Now from time to time, often actually, mobile data connection goes down ..requiring a restart to get it working again... Can you help?
Thanks!!!!

Welcome.

Have you tried cleaning the SIM?

Or just bring it into the carrier. (But I suspect something wrong in 4G-land in the phone.)
