To dial direct, dial "011" + country code + city code + number.
Note: Calls to Canada, Puerto Rico, Guam, U.S. Virgin Islands, Northern Mariana Islands, and Caribbean countries listed below do not require you to dial "011." These numbers are dialed using the 1 + area code + number just like you call numbers within the United States. No country, city, or international access codes are required.
Customers calling from the United States to a mobile number in Mexico must dial a "1" after the Mexico country code of "52" and before the 10-digit local number.
