Any MTNL Mumbai user here? There plans seem to be great and roaming is cheap coupled with superb BSNL coverage in villages/small towns. How does their service fare in Mumbai? Do you get problems with signal strength etc???
I used to use MTNL Trump. They had a bad network. But recently, it seems, their network has improved. I am currently using Orange. They rip you off and their network isn't all that good either. If you're in Mumbai, I suggest going for Reliance or Airtel (if you have a GSM handset).
