Thank you so much jio.good network coverage and it almost give 5 months of free internet and call and sms. It created history by the only network in india which provide free call, internet and sms for such a long period.its network coverage is good.i always travel by train or bus.but most of the time it catches network.the internet speed is good.in the morning it works in 3/4 mbps.but when day grows its speed slows down.customer service is awsome. Call speed is good.but in the evening call drops always.its call normally dont pass to other network like bsnl, airtel and docomo.it also provide live tv and jio money.which is very much useful.it saves my 5 month mobile bill.thank you jio. But the demerit is that it doent work in all phones and most of times its call drops and after the welcome offer its packs are very large and expensive.if the company solves these problems it will be the best network in india.
