If you wish to make the best use of the Jio Welcome and New Year offer, have a 3G phone or need a backup portable WiFi device, this is the device for you. It’s battery lasts well above 6 hrs, data availability much better than with a Jio sim on a 4G phone(have those as well). The best thing is being able to make HD calls and use the entire suite of Jio apps using this device. It’s a high recommend at 2K and the fact that you will get free data to use until Mar 31st means you will recover above your investment. Points to remember: The Jio Sim will have to be obtained separately using your invoice. Also, this device will only work with Jio sims.
