I'm heading to Europe for a month and could use some advice on what my best options are for a cell phone while I'm there. I'll be driving through five different countries - Sweden, Denmark, Germany, Netherlands, Belgium, France. Should I bring my own phone and pick up SIM cards along the way? Or should I just get throwaway phones in each country? I could use some advice from those of you who live in these countries - and know about the cost and availability of both SIM cards and disposable phones. I'd also appreciate suggestions as to what model of phone I should be looking for, if I decide to buy a used phone to take with me. I know it has to be GSM, and unlocked, and either dual or tri-band . . . but if someone could translate that for me into what exactly I should be searching for on craigslist or ebay, that would be a huge help! My phone is CDMA, so that will be useless outside the US. Thanks!
