Hey guys I live in banglore the data speed of my phone is very fast and loved the speed I finish my 1.5GB data in 1 hour. Im happy with jio and its cool offers . I didnt go with any airtel sim because they dont offer many prime applications like jio so I had to go with jio. There were no calling issues in my area. Im very happy now because they extended prime membership till march 31st 2019 for free!
