I Started using Reliance CDMA when I went to my Second job and got a company connection. in 2006. But since then I am a fan of Reliance CDMA and use it for personal use also. the best part is the CDMA reception and Clarity of reliance is awesome even works in many basements also.
The other I love there 1299 unlimited plan. IT IS truelly whats called UNLIMITED, it is like UNLIMITED LOCAL & STD Calls to any network all over India. and also unlimited roaming, Since I travel alot due to sales it is like same plan all across India. the only problem I had was in Kashmir they dont have a reception for CDMA. rest from North to South India to West India I have never had an issue with the network.
It has like 3000 SMS free sufficent for 1 month, and unlimited Data for Internet. specially after comparing my bills from last company from 7- 8k per month coming down to a bill of 1500 inclusive of Tax. is a great Deal.
