Recently I turned towards the Reliance GSM service. And now I can say just go for it. It has best network coverage in town (Bandra- Mumbai) in my area there is some network problem, and continuous disconnection between long calls. Reliance the only one who provides best network in my area.
According to me here are the reasons which makes me go for it are.. Best network service just like CDMA. Affordable tariff plans. You can switch your sim to any handsets and there are no limitations of hansets
Reliance has also introduced some attractive std tariffs. Under the plan for the first minute the calls will be charged at the arte of Rs 1 for local calls and Rs 1.50 for STD calls. However, from the second minute onwards the call rate will be only Rs 0.50 for any call anywhere in India. And we know reliance is the only company who provides cdma and gsm service togather, which is 3G enabled..
