I have a SIM card for Brazil/South America and Kolbi(Latin America). I don't know if those are GSM or CDMA networks. But the above description suggests it matters whether or not I have a GSM or CDMA phone. So I am a little confused there. From the links below I'm starting to see I probably need a quad band, GSM phone.

CDMA does not use SIM cards
