Dont forget the ever increasing subscribers. I dont think these operators can handle the load. While the staff/employees not being able to keep up with the workload. One thing about the tower, if this goes on there will cell towers in every homes soon! Even now we have two cell towers in our neighbours' buildings.I thought the reason for the drops was that the license of many towers have been cancelled?
As for the connectivity issues i dont think that there is any operator with good coverage all over india. Aircel was great many years ago but now its like the worst. I liked Vodafone best in South Delhi. I often got highspeed data on 2G packs. In North Delhi Airtel is favoured i think. Reliance was also good in some parts. But MTS the worst of the lot! I used Voda (for good connectivity) and Aircel because of its cheap plans.
Vodafone roaming also works good here in Imphal. My brother tells me that Reliance is also good. Airtel used to be really good offering decent network and regular 3G offers. BSNL and Aircel the worst. I now use Idea only. Want to know how bad BSNL is? I got disconnected three times during ACTIVATION CALL. Lol. So if the state-run operator is also this bad doesn't that mean that the govt. is also at fault?
