I have been using this Tata Photon Max Wi-Fi Data Card for the past 1 years.my tata photon a/c no- is 921063981.i am getting very slow speed so I decided to close the connection & I put the email & I received the confirmation email of discontinuation of tata photon internet service as on 12th april 2016.i have not used even any data during entire month and I have got the bill of Rs.3552- which I was paid.This is really very worst experience I faced with Tata Photon, I don’t know how to rate your service but it is developing very bed service reputation.
