I am using jio from its 1st launch.so I got all the offers provided by the company till now.i am having 4 jio sim and my father mother sister wife everyone is using jio.the most important thing is its network quality, its very good.earlier in my village there was poor network but after I mailed to jio administration they looked after and now strength of network is awesome and they just did it in only 2 month after my complain.one of the vest thing is if your jio balance ends anytime still you can call any jio number all over india at free and use internet at low speed.the cost of the monthly packs and data is also very good.
