Reliance Jio made a revolution in India in telecom sector. Reliance Jio has become the first telecom company to provide free calls and data for their customers. The network is available in all the areas. There is no area where we experience a shortage in range whole using jio sim. I have experienced range issues while I was using other network operators. But till now I have not experienced any issues with the jio operator. Jio is a 4g sim, so the internet speed is good and works at all the locations even in hilly areas. Jio provides a good customer service and service centers are also providing answers for the enquiries very clearly. Jio is not charging much amounts for any offers. They are providing offers for a minimum of three months. At the starting stage jio provided free calls and free data for first three months. After that they told the customers to recharge it with ₹309 rupees for continuing the offer for next three months. They are giving one GB data for 1 day. Per day one GB data is gievn. If the person exceeds the data no charges are deducted they can browse in 2g speed. Jio made a revolution of changing MB to GB. The customers who were using MB of data has started to use GB of data. I has happened only because of Jio. Even I have also started to use GB data now. And also jio helped to reduce the offer rate to an extend. Now the offers provided by all the network operators are affordable for everyone.
