Our job is to find the catch. While using the Photon Max Wi-Fi, I wished that the device had a battery or that Tata had offered a battery pack as a bundle offer of some sort. While you’re travelling, sometimes you may not find a power socket or working USB port. For those cases, we recommend purchasing a portable battery pack – one that lets you plug in USB devices.Tata promises up to 6.2 Mbps speed on the Photon Max. The speed we got ranged between 1.4 Mbps and 2.6 Mbps, when tested on speedtest.net. By no means should this be considered slow. Three to four people had connected phones and tablets to the Wi-Fi network and were constantly browsing, chatting and updating apps. The connection did not slow down much during that test.i this manually set to tata
