One of the best networks in terms of call charges, honesty, network and data plans. To start with let me elaborate my GSM tariff
Rel-Rel 5ps/min
Rel-Local mobiles 30ps/min
Rel-landline 50ps/min
Rel-STD 60ps/min
All national and local messages at 5ps/message.
Monthly 100MB free data(2G)
the tariff says it all. You can also add extra packs to this tariff. Usually people think there may be hidden charges and even I thought same but oops I was wrong. They have not deducted even a single paisa from my balance. Network connectivity is best and no issues with anything. The best part is you can browse net even at zero balance.
The only sad part would be 3G, it is yet to be launched in Karnataka. Overall this is one of the best and honest network I have ever used. NOTE: Please beware of the CDMA network as the above review is only for GSM. There are many complaints regarding CDMA. I recommond only GSM and Karnataka circle in specific.
