Everyone praised jio sim so I bought jio sim but unfortunately where I live that area has network error for jio. ZERO NETWORK. So I used jio whenever I go out from my place. I inserted jio sim in my iPhone 5 so there is one more obstacle in this, I can't make and get calls. ufff!
No doubt data speed is good but not at all worth for me still I live in city/town and facing network problem. Airtel is costly but best.
