Anyone traveling with an iPhone may want to use a dialing app called PushOneCode.

It knows - where you are - using GPS and brings up all local area codes for easy dialing with just one push.

Also knows how to dial from where you are - to anywhere in the world - again with just a push or two and you can complete the call inside of the App.

All emergency numbers for every country in the world are also in the app for use in emergencies.
