If you find that your European cell phones will not work when you take your next trip to Disney World, you have a couple of options. Firstly, you could consider buying a dual band phone, which is perfectly suitable for use in North America. This will likely be your cheapest option. A tri-band phone, could be useful when your vacation concludes, as such phones can be purchased to work in all of the European, Asia Pacific and North American markets.

The latest 3G dual-mode phones incorporate a combination of GSM and 3G technology. 3G may be your savior here, as they can be purchased for use in most countries. However, make sure that you get the correct frequency combination.
