4g not working in my M31 mobile with airtel network

[AshrafDil]

Even after network mode is selected to LTE auto, data is always showing G in my M31, with airtel sim.

I have tried in another mobile and sim is working fine with LTE data.

Any help???

Seems no problem with operator cause it is working fine in another device.
However i have even rest networking setting but no use.

Depends on which region you're currently living nd also your sim card. However, if you're sure that the problem isn't with the Network Operator or Carrier, then you can try one of the following -
1. Using Samsung Members Diagnostic Tool to diagnose your device.
2. Doing Factory-Data-Reset. (remember to back-up your data)
If neither works, the only option left is the Samsung Customer Care.

Hello I'm facing sign in to network in samsung M31 mobile we have check sim settings but issue same

[Members_rFOIwT5]

Even I am facing the same issue in M31. My brother's phone was also the same M31. It worked fine till I updated it to the latest software update. After updating, same issue with Airtel data. Jio sim is fine and the same Airtel sim is working fine on other company devices.

See, I have recommended Samsung mobiles to all my family members and I myself bought 3 of them. So, please don't make me reconsider for my future purchases.

Thank You.
