Hello friends I am a jio sim user and share my review about it’s service, calling quality, massaging, internet speed and recharge. On the begging there is network problem in villages but on highway and big cities no problem. Now it provide all place coverage with good signal. There is customer support all 24×7 hours with good service and shootout any problem in the time. In the begging internet, calling, sms all free of cost. Now it charge very low only for net, local and national calling and sms still free. In 399 rupees they provide 1GB per day and after that 128Kbps whole day. Pack validity for 84 days. It is far batter than other service provider company in India. You should try it if you are not a jio customer and if you are than agree with my review.
