We are aware of the fact that this generation need 4g instead of 3g nad 2g. So to fulfil our needs reliance had launched his new product JIO with unlimited free calling services and fast data services. Yes, so in india everybody wants to buy this sim because it doesn't cost you money, it requires only your adhaar card and a photo. And everybody hated it because of call drops and alow internet connections, but the people has to understand that they are getting free calling services , then also they have problems . Though jio is not responsible for call drops , companies like airtel, vodafone, idea are responsible for not allowing to receive calls. Though all this problems are getting solve. So I hope after few months we get a fast 4g speed. So thank you for visiting and please follow me.
