Free Long Distance...Viva Mexico!

I live in Mexico, and, last

January Telmex (Think Slim)

announced that they were 

giving me free long distance....

anywhere in the world. This was

on my phone bill, so, with my 

limited knowledge of Spanish,

I placed a lot of long distance

calls, and, my bill went down!!!

Has anyone else had such a 

nice experience, albeit, on such 

a mundane level as this, in 

the last few years?
