    Hi guys, I searched far and wide for a direct answer to this but can't find anything. I just purchased a Treo600 for a person in Canada who bought it with Rogers service. I am an AT&T customer, started service in July 04. When I put my SIM card in I get an error saying " SIM not allowed"

    Is that a matter of just unlocking the phone? or do I need to update my SIM card?

    Thanks to anyone who can help!!!!!

    Yes, you need the phone unlocked
    Palm III > HS Visor > Treo 600 > Treo 650 > Treo 750 > Treo Pro > PrePlus GSM

    "95% of all software issues are due to USER ERROR."
