It is a very useful device. As we know that reliance jio is giving good internet services at no cost till 31St, March. It is useful if you have a 2g or 3g phone and you want to use a fast 4g network. Although you can connect it to jio 4g voice, that can be easily installed on any smartphone and you can make free voice calls, HD video calls and also you can send messages. It is very easy to use. It comes with a long battery life. Although you can connect upto 10 users at a time.
There are some problems with it also. As we know that jio had started a limit scheme for these devices too. At the time of activating the jio sim there are many troubles.
So guys buy this device if it is necessary to you. If you had bought this than enjoy the services. For any queries about jiofi you can open mindedly ask me.
Thank you. Have a nice day!
