I am using jio service from last 5 month.firstly they said that they provide free internet, free call & sms now they are going to charge for every service and extra 99 rupees for membership.they said that they are providing fastest internet service in india but mostly time you get 2g speed no 4g and network coverage is also worst in all telecom service.mostly time when we try to call we get network busy tone.i can say that for a single call we have to attempt 5-6 times.so finally I can say that jio providing free service but valueless service.i mean useless service so its better to pay money for other company if you want a good internet and network.
