Earlier vodafone used to be a good mobile network provider.But since a year it has degraded a lot.
Especially the coverage in areas where it used to be good has gone bad like that of idea.Calls gets disconnected even if the climate is good.
So one can just imagine how bad will be the network quality in non coverage areas.Use internet on mobile on their network and the bill shoots like anything.They are just interested in collecting the bills.For bills they will give n number of sms and calls.But to resolve customer issues no sms no calls.
