I am using reliance jio 4g with LYF FLAME 1, though I had oneplus one but had to but that lame lyf phone 5500. Phone is really sad with outdated hardware snapdragon 210 processor . Touch is like of 10 year old phone have to click 10 times phone hangs a lot so you can even do anything on that.i used as hotspot battery backup 30 min . When I used as hotspot with continuously charging still battery discharge wtf? Reliance. About jio 4g services are awesome playing online MMORPG for a month no even a single disconnect. Low latency and zero dala loss . it almost covers all national highway tested on Lucknow to nagpur road trip. Awesome. Though speed is diffrent in diffrent areas somewhere I get 11Mbps and in mine frnd home I get 50 Mbps. Overall if data plans were cheap and unlimited it will change the course on india
