I am using Tata photon Max wi fi connection since last 1 year. but I am enjoying its best speed in half of the month only other wise it looks like 2G speed. customer care service also average. at the time of full network speed of this device is excellent. mainly coverage is available in the city area only. as compare to price of plan the service is not up to the mark.
Overall the response of photon max is average, due to we have option to use it in mobile as well through Wi Fi Connection.
