We are aware of some difficulty in placing calls to certain areas. Some additions may be needed when entering the phone number in an international format.

Mexico:
Calling a cell phone from outside of Mexico: Please add a 1 before the area code (e.g.: +52-1-624-166-6887).
Calling a cell phone from within Mexico: Please add 044 or 045, then the area code, then the number.

Argentina: Please add a 9 before the area code for calls to cell phones in Argentina.

Brazil: Please be sure to include the 2 digit area code before the 8 digit phone number.
