I have an idea sim in my mobile. There is no proper network in our town and nearby places. It shows that the network is connected to another network provider and changes the symbol of Roaming. Every time we want to call through idea we have to wait for the connection to be established by finding and registering the connection in phone settings. I thought it was my mobile fault but later I came to know that it is same for every one around us. Data services wont work. It will take 2 hours to download 10 mb of data for us.
Really this is very worst service when compared to other providers.
