First,Ive finally learned my lesson after three international trips with horrible phone bills following the trip. Tell me whats the easiest route to go about getting a travel cell phone/disposable cell phone for international travel.I will be away for 13 days in Italy,France,Spain and Mediterranean(cruise). I also have the Iphone 4S-is there a way to use an intl SIM card for lower rates without screwing the phone(or my home service)up?
Speaking of Iphone,how hard is it to change the battery if I buy an extra battery to take(will still use phone for camera,WIFI).Are any of those "power up" devices worth investing in instead?
Thanks for all help!
