Personally I have never experienced any problems in. Vi VoLTE
Good for you. But NOT for most people and that is the real problem.
Peoples perception has became bad about Vi just because they are not investing
The reason behind the change of people's perception is again VoId only. Especially their management is having zero confident on themselves.
But to be honest, 5G from Vi is just 10% better than 4G+ in my experience.
So their 5G is also NOT that great, even for a die-hard VoId fan like you. But still that is OK, if they have started competing with big players and NOT follow them like the Hutch Dog, all is good. Problem with VoId is they are increasing rates almost same as Airtel. Atleast that is now changing with new cheaper UL 5G plan.
They should focus on densifying band 41 sites
I agree.
get that extra 20Mhz contiguous block and bolster band 1/3 to 15/20Mhz wherever possible.
Unfortunately Spectrum cost lots of Money. Even VoId is thinking of returning some of their spectrum to lower their debt to Govt, let alone "bolster" 20MHz of spectrum wherever possible.
Vi will be miles ahead and people will opt for them above Airtel atleast.
Not in the foreseeable future.
This 90000 Crore will look like peanuts in two years of time.
For whom? VoId???

Again, if only VoId management has even 0.0000001% of your confidence on VoId, it will be in a better shape now, imho.
If you come out of your city, then you will understand.
It is you, who have to come out of the mindset that "VoId is great for me, so it will be great for everyone". Because in my ground floor, VoId 4G coverage is spotty at best and unusable in some rooms. Not believing me? Then, just look at the number of customers leaving their network.
I get approx 95 mbps on 4G on Vi
Good for you. When 95% of data customers of VoId get at least half the speed, their customer bleeding will take a u-turn. Let us hope that happens soon.
