Priced at Rs 1,999, it can serve up to five devices and delivers a speed of around 6.2 megabits per second.
"While wireless data connectivity has greatly increased the level of user experience on mobile devices, Photon Max Wi-Fi promises video speeds and will allow data-hungry applications to run seamlessly between multiple users," Tata Docomo President Operations (Mobility) Elango T told reporters here.
He said the device is currently available for CDMA customers only but in coming 10-15 days, it will be available to GSM users also.
Existing customers of Tata Docomo Photon can upgrade their services to Wi-Fi by buying a new device and there is also a device cash back offer which makes the device free of cost in 13 months.
Customers can opt from a wide variety of unlimited Wi-Fi plans ranging from Rs 650 to Rs 1,500, the company said.
