I have been using Jio’s SIM for approximately 1 year. I want to tell you that jio is a very good service provider. If I can talk to jio’s network then I can say that I have to face a little trouble. Because there is sometimes no network in it. That is why I can not use any feature in it. Apart from this, its customer service is very good. If there is a slight problem, we can get help immediately. jio is a very good mobile operator, I do not have to give any extra charge to any of us in this. It is much cheaper than other companies. In this, I have to pay Rs 399 and I can use unlimited calling and internet for up to 3 months. What I like most about jio is that it does not seem to be roaming in. We can call anywhere in India. jio is a very good mobile operator for me. Which meets my needs in less money.
