Its been one month I got reliance sim and started using in my iphone . Network are horrible in my state ( madhya pradesh).
My friend get tired calling me but call never reaches. customer service is hell. I tried calling them it takes more than 20 min for them to pick your call.
And if u want to talk to senior representative u r screwed for hour. U will be fortunate if they answer u. I will port this sim soon specially its not working well in my state.
