Reliance come back with its huge commercial 4g sim.
This is the best 4g sim I used speed are superb u can download speed upto 60Megabits and while upload speed upto 12 Megabits
Recently Jio launch commercial providing unlimited data calling sms untill 31st december 2016 and there is also some catch that is u can only use 4gb /day under the welcome plan and 100sms/day. Speed are throttle in cities bt speed is quite good compared to others opertaor.
Jio 4g sim is available at digital store.
personally say it is very gud even it excellent for heavy users it is best .
