Pretty sure there needs to be a country exit code dialed before the #'s but I am guessing there may be a spanish/english problem once i do so i rather cll down with someone that speaks spanish

Calling Panama from the United States explained:

• 011 - US exit code; dial first for international calls made from the USA


• 507 - Country Code for Panama


• Phone Number:


• sample call from US to a landline in Colon:  011 507 4## ####
