Telephone…

52 (Five Two) is the International Country Code for calling Mexico.

00 (zero zero) is the International Dialing Code (Prefix) you use to make an overseas call from within the country of Mexico. 

Calling Cards

Some calling cards work in Mexico, including a Costco MCI calling card, purchased in the USA. Just call the mci operator before leaving home to get the international access code to use in mexico.  Just make sure your card has an access code for México.

Internet Cafes and Call Centers

You may also want to check with Cyber-Cafes and Coffee Shops for Internet Calling. Many places now offer VOIP calls and these are usually the best rates.

Pay Phones

You will see regular LADA Tel or TelMex payphones in many public areas, along streets, in plazas. These do NOT take coins, but rather smart cards with a little gold chip that you can purchase in most kiosks, supermarkets, etc.

Cell Phones

Many American cell phones work just fine in Mexico, depending on your location. Just call your phone company for instructions and rates.  If your phone doesn't work where you're going, you may be able to find cheap prepaid local cell phones once you are in México.
