I have purchased a new dongle card of tata indicom photon+. which has speed of 21.1 mbps at the maximum.
I am using this dongle from last 1 year and had no issue from then, and started to use it for my downloads and uploads and really I got a great speeds which were promised by the tata Indicom photon.
I have to pay 800-900rs. monthly and I get 4 Gb per month and unlimited browsing after that I have to recharge again.
it is really a great product at this price as I am totally satisfied with his product and refer everybody to use this.
