Guys I've been using  galaxy note 10 plus from last November. 

Since 7 days iam facing network connections issues 

Signals constantly changes from 4g to H+ and sometimes E 

Currently iam using airtel sim

Initially I thought it was sim problem and I went to airtel store and bought a new sim and problem is not resolved 

I restarted my device 

Network settings are reseted 

Apn settings are default 

Still I face network issues 

This is really bad.

Please perform the below mentioned steps to resolve the issue:

1. Check device network mode settings
Settings > Connections > Mobile networks > network mode SIM1 or SIM2 > network mode.

2. Check network operator settings
Settings > Connections > Mobile networks > Network operators > Select automatically > OK > Registered on network.
