Hi All, Personally I am using this product from last 8 months called Airtel 4G hotspot. This hotspot is very easy to acess with the mobile , pc, and laptop. If 4G network is not available you can set 3G or 2G network also . All the facility is available in hotspot software .you can acess videocalling, voice calling , massenging, and also if you want to recharge your account, you can recharge your account simply using Airtel 4G connection portal. You can check your internet balance also online in the connection portal. This device you acess as hotspot and wifi connection in the 3G and 2G handset if your handset is compartable with the Y5.Its best internet 4G hotspot than other operator.
