Do calling cards work in Mexico?
You can buy calling cards in Mexico that work in the public telephones. If you use them for calls to the US the cost per minute is 5 pesos (about 50 cents). I have used them in the past, but on my last trip I took my cellphone after checking with my provider, Verizon. The calls were charged at $1 a minute, but it came in handy on a few ocassions.
