I am using 2 Sims of Airtel on Nokia 6.
One sim is 4G enabled,the other is 3G enabled. But when insert both SIMS, both are showing 3G.
When I use single sim also, 4G is not activated. I put 4G are preferred network, that also doesn't work.
I have done Factory reset as suggested by Nokia support team, even then the problem is not resolved.
Can someone help with this?
