I'm using an AT&T Palm Treo 750.

I unlocked it before coming to Argentina.

I bought a CTI Movil prepaid SIM and a Claro $20 card and activated the SIM by dialing *22# (Mar del Plata). After the "overnight" activation, I entered the Claro card #, then it came back with a message of my balance.

The Claro card came with some info about the rates for calling, i.e. $.35 for the 1st minute, then $.19 after to the US.

I am not able to call the US with it. I have tried using "001-areacode-phone#" but a frantic-sounding lady speaking Castellano muy rápido makes my brain go haywire. All I could catch was that she was telling me to call *611 for more info.

Then a message popped up on my phone saying, "The call barring settings are now enabled."

What the hell does that mean? And why can't I call the US from CTI/Claro?

I have no call barring set on my Treo. Everything else works fine...local calls, SMS, etc.

Please help!
