Tata Docomo has launched a device called the 3G Wi-Fi Hub, a Dual-mode device which works on both TATA Photon Plus CDMA and Tata Docomo 3G network. The 3G Wi-Fi Hub is nothing but a pocket WiFi router similar to the Vodafone MiFi and you can share your internet connection with any device that is Wi-Fi enabled. We think it’s a pretty interesting device as you can get reliable data access from either the GSM network or CDMA network.
