Phoning Costa Rica and free map offer

Some practical information here:

Problems phoning Costa Rica? Telephone numbers in Costa Rica changed this year from seven to eight digits. Many websites have not been updated yet.
If you are trying to call Costa Rica directly, first dial the access code and area codes: 011 506, then add a 2 to any number that begins with 2, 4, 5, 6, 7 or 9 (land lines).
Add an 8 before any number that begins with a 3 or an 8 (cell phones).

Examples: if a number in your guidebook or on a website is 645-5223, you would dial 011 506 2645-5223.
If a number is 397-3489, you would dial 8397-3489.
