JioFi is the most effective and affordable product in wireless router segment. It’s over one and half year since I am using this device and I am quite impressed with it. This provides you both internet access as well as calling facility through a single device. It’s having a sim slot inside it, functionable only by a Jio sim. By registering your device on Jio4GVoice app in a smartphone, you are ready to use it by calling through it, sending messages through it and accessing internet also. It provides a great internet speed as well as battery life of 12 hrs in one charge. You can connect upto 10 devices with this portable router.
I am quite happy, using this device.
