It's never too late to respond

To update my own thread .. I have upgrade with Cingular .. through my company I was able to get the Samsung SGH-x507 which is a quad band and which has the international capabilities. Our service is through Cingular. The lady at my company who deals with Cingular said "Apparently Cingular doesn?t unlock phones so that you can use other SIM cards. But they?ve added the international roaming to your phone do you can use it abroad."
So this probably isn't the cheapest route ... but we are only taking the phone for emergency purposes (receiving calls from the US) and keeping in touch 2 or 3 times with the family back home (calls from Europe to the US). I think with International roaming I'll be paying $1.29 a minute. eeks.
Any tidbits of information on how to cut down on cost other than telling my family not to call all the time. The only good thing is that my friends have my 'normal' cell number and not my 'work' cell number, which is what I am taking to Europe with us ... so I won't be receiving calls or voicemails from them. I thought about using a calling card ... but not sure how that would work or if it would save us money in conjunction with my new cell I got.
