Dialing to/from Mexico

Even though 90% of all land line telephone service and 80% of the cell phone service in Mexico is ultimately controlled by the same person (Carlos Slim), dialing other numbers is bizarre and confusing. Here are the FIFTEEN RULES you need to memorize if you want to call to and from Mexico.

> Land line to land line: dial the 7 or 8 digit telephone number without the area code
> Land line to cell phone: dial 044+area code+number
>Cell phone to land line: dial area code + number
