calling 800# in USA

Does any one know how to dial a 800 phone number from Mexico? It was posted on this site years ago. I have both a usa phone number and Mexican telephone number with a mex/usa calling plaon.

I use the simple low-tech "old school" method:

Dial 001 880 then the 800# as U have it.
A recording comes on that says something to the effect of:

"This number is not toll-free if dialed from outside of the US".

Z Rob's link

has the procedure, and the conversion prefixes of the USA toll-free #s when calling from MX.
