Personally I experienced Tata photon+ data card and want to make aware everyone that please do not use Tata data card and products, they will assure you to not provide quality, speed and service.
Connection reliability is 0, better to use 2G service in your mobile, that is much faster than tata photon data cards.
Service & support- they will send engineer to your location to check speed but no solution, you will just keeping raising request and they will have same answer but no concrete solution. they will never improve their service.
