Just make sure you have an unlocked phone or have it unlocked before you leave,do a google search for cell phone unlock,many ones out there.Also even more important,make sure your phone is a tri band or quad band with at least one of these bands- 900,1800 or it will not work in Europe even if it,s unlocked.Unlocking only frees it from accepting only 1 carrier,s sim card
