I bought idea sim june last year in 2015. this is not a good operator network and it is vert very slow network and bad signal. I used idea sim for 8 or 9 month than I switch it to vodafone and my experience is very bad. unwanted deduction of money from the balance and slow speed of internet even in both 2g and 3g .It simply give you more costly plan and services. idea is the worst mobile operator, it increases the rates and puts on the offer without informing you when I called customer care they give unacceptable answer. I wont use this sim again.
