What type of cell phone should I get for international travel in Europe? I would imagine it would be an unlocked GSM quad band phone. Unlocked so that you can use a local SIM card. GSM is the most commonly used network technology. Quad band would allow the phone to work on more networks. Are there any other specifications I should look for? And where should I buy it? Someone told me unlocked phones are cheaper in Europe than the US. Thanks for any advice you may have on this.
