Hmm...I didnt vote for any particular operator. Here is why:First the pros...MTNL - Best plans, best value for money, free roaming!Airtel - Nice plans and good networkReliance - excellent network, CDMA Advantage, Good plansOrange - OK Plans. Good networkNow the cons...MTNL - Bad networkAirtel - Bad CCReliance - Billing issuesOrange - Crappy CC and EXCESSIVELY HIGH Charges compared to other operatorsI am currently with Orange. The reason I shifted from MTNL to Orange is because I wanted a better network. But there are many trade offs in the process. But the worst part is that Orange has bad network near my place. So I constantly have problems with receiving / making calls. May be its just that there are too many Orange users in my area. Dunno. But atleast MTNL network didn't have so much trouble at my place...
