On my OnePlus 7, Vowifi gets disabled after 2-3 hrs when my phone is idling. It also stops working in Mesh network when my phone connects from 1 node to the other. I have to enable/disable Airplane mode switch manually to get Vowifi back.
After using Airtel vowifi for 2months I must say that my jio volte was 1000% times better than my Airtel vowifi. I agree it is in testing phase but smartphones these days know to change the network connections to get the best output. To put in terms of value to understand easily I would say:
Call drops : 40-50%
Calls not getting connected : 25-30%
Speed issues while on call : 60%
Speed issues when not on call : 50%
Overall I am completely fed up with the services of Airtel. Waiting for 1month to complete my 90days period and port back again to Jio which has superb indoor connectivity.
