Hi, I recently bought a Telstra HTC Wildfire and unlocked it by code to use my 3 SIM card on it. However, after unlocking my mobile, when I choose the option "use phone for data connection when wi-fi is unavailable" it doesn't work. When i go to mobile network and network operators, I select to search for networks and the phone is automatically connected to "3Telstra(3G)". They also show 3(3G) and 3 networks, but when I try to select any of them, it says that the SIM card does not allow the connection to this network. I don't know if one thing is connected to the other, but I always used my old phone for data connection with the same SIM card. Does anybody knows how do I solve this problem?
