I took my Cingular cellphone with me on our Panama Canal cruise. Although I didn't use it, I kept the phone on so that I could see who was leaving messages from the phone numbers listed in missed or incoming calls. Never listened to the voicemails though. Imagine my surprise when I returned home, viewed the bill and discovered roaming charges on the voicemails simply for having the phone turned on. A call to Cingular and my bill was corrected but let this be a warning to others!
