Bell Mobility 8830 will not work with North American GSM (i.e. FIDO or Rogers, AT&T etc.), as North American GSM frequencies (850/1900 MHz) are different than those used in Europe and most of rest of world (900/1800 MHz). The 8830 only has the 900/1800 MHz bands for GSM, in addition to the CDMA bands.
A Quad band GSM phone (850/1900 and 900/1800) will work in Canada/USA as well as rest of world where GSM is deployed.
I believe the GSM portion of the Bell 8830 is unlocked (allowing you to use a European carrier SIM card), but I am not 100% sure. You should confirm with Bell. You could also roam with the Bell SIM, using your existing phone number, but will be expensive versus using a local SIM card in Germany (you will obviously have a new phone number while using the German SIM card)
