Hi freinds I am a user of tata photon max I am using this dongle since 2 year ago and I have a very bad experience of it .First of all I want to tell you that though I am a postpaid user having a 10 gb data validity I faces many problem regarding its connectivity in other devices i.e my mobile it connectivity is first on pc I face many problem regarding the browsing uplods and download it have a less download speed as compared with its uplod speed so from using it I have a download issue sometimes after using it more than an hour it disconnects automatically at many times I have to waste my time in connecting it and after use of 10 gb the speed is lower than the 2g data.
