Then you will have to find a GSM cellular carrier.

Cingular is your best bet, since (unless your phone was represented as being 'unlocked' by the seller), it probably only works with Cingular (who bought ATTWS, the US carrier that cut the original deal with Palm).

IF the phone is unlocked (and there's no way to tell without truying a SIM card), then it might work with other carriers. Forex, I bought mine from a Canadian customer of Rogers, which sold the W unlocked. I put a T-Mobile SIM card in it at the T-Mobile store, and it worked.. so I signed up with T-Mobile and got a data-only account with unlimited upload/download and 500 SMS/month.

But, first you must
find a GSM carrier.
