I recently baught a new reliance jio sim and I actulally loved the speed it provides with the awesome fast 4g speed of the operator and with the network which is unbreakable even in the elevator lifts and the network provider provides with a lot of services which is absolutely free and which could benifit you in many ways such as emails or sending any important sort of information or documents. when the speed of the web browser slows down you can also call the customer service of the phone and the customer service of the phone is quite slow and no use of calling the customer service.
the reliance tele communication is providing the country with free of cost service till 2017 end.
