I ported my Airtel secondary number to BSNL, and now regret. I still face that OTP lag, and coverage is also really bad. The plans are also confusing. They run a number of plans, confusing at least for me.
I'm now on Rs 91 plan which is for 2 months (Kerala Circle). Thinking of porting back to Airtel because of BSNL's service.
My family plan for Airtel runs fine, and better coverage and clarity that JIO. 5G is also awesome, and I have around 264GB for this month after carry forward
. I'm enjoying the unlimited 5G
