It's a very good mobile operator which offers good speed of internet at less compared to other operator's like airtel and Vodafone.jio is the one and only one to offer internet free data's for many month's while none other's gives such a offer.i enjoyed for a year.i really whole heartedly thank jio for that.now also it gives lot of awesome cash back offers.Like shown in advertisements it makes everyone to fly by it's services and offers.it gives better coverage in village than any other networks.when I had faults in my jio voice app I called the customer care service, they answered very politely and gave a detailed description to rectify and avoid such problems .it was a good experience.it also gives perfect missed call alerts when my mobile is switched off.even though some times I delay to recharge, they're not cutting internet.they are giving free internet but at low speed.so I highly recommend to use jio which is reliable and good.
