Reliance 4g jio sim is a good sim for internet using purpose its network is to good in mostly area but in some place its network dont work properly and also the internet speed is slow but more place its good work I bought this sim from nehru palace first time I spend 2 hours to buy reliance jio sim in nehru palace . I want to say its a free sim in this country but you want a 4g mobile to use it . you have a uid then you buy it other wise you cant. Its totally free . All calls and internet use totally free you have no pay any call and internet uses.
