I wanted to know what is the use of SIM slot which is provided in Tata Photon Max WiFi and if it works, which SIM card can I use? Can I use any SIM card for Internet?
You can't use any SIM card in the Tata Photon Max WiFi device because it's tied to the Tata Indicom carrier. You will need to unlock the modem before using another SIM card. The device comes with a data plan and a SIM card from the Tata Indicom carrier network.
