I had bought this JioFi from Reliance Store the JioFi is a very good product, In my Opinion, you can buy this, many people are telling that its speed is not good but I think, after buying this you can use this trick to get good speed you will definetly get speed. If you are using in a home, first of all, you have to keep this device vertically in different places like nearby your all windows of your house and check it that where you are getting the good speed because if you kept it in a middle of your house you will not get the speed. Finally, If you found the place where the speed is good remember always place the JioFi in a vertical position on that place you will get good speed. The service and support of jio are very good. I am attaching the proof of my purchase with this thank you.
