I started to use relience CDMA service from 2008, and I was very much happy with the network and charge of calling and msg. and still I am using same sim after converting into reliance GSM. but the network of Reliance GSM is veryyyyyyyyyy poor. I am totally fedup with the service of reliance gsm network. Even the call charge too much high compare to other network. This is my personal request to the company that please improve your network service and offer best top-ups to your loyal customers who used it since last 8-9 yrs. bcz we need good network and best charge, even I dont want to go for other network if I get gud service from your end.
