In today we all know about Reliance jio, because they pick a best way for marketing, that is give free data and calling.In my personal opinion Jio network coverage is very nice form 2 months, in starting its network is so poor and connectivity also so poor but now all is good.I also feel that in train Jio network is unbeatable.In starting its customer service is not good because may be due to less workers, but now its custome r service is improved.Till end of the march(31 march) it’s totally free, after march they give best and cheap plane in my opinion.
