A practical dialing detail for Guam
A typical Guam number looks one way locally and another way once you add the country code. A local example like (671) 300-1234 is often written internationally as +16713001234. The other wrinkle: +1 is shared across multiple countries and territories, so the country code alone does not always tell you the destination.
