I have just replaced my Samsung SGH-i616 (Blackjack 2) which is on the Fido network, with an unlocked Samsung SGH-i637 (Jack) which was an AT+T phone. I put my Fido sim card into the new "Jack" and the phone works as a phone, but it will not send or receive e-mail, it will not log on to the internet, the call display does not work, etc. It will connect only through Wifi if I am near an access point. It appears as though I can't access my data plan with Fido. How can I remove or change any of the AT+T settings?
