For anyone in Canada that gets an Amigo Sin Limite plan in Mexico for either 100 or 200 pesos, you can set up an account with them on line and use this plan to phone anyone from Canada to anyone in Mexico, USA or Canada. When you want to phone a Mexican cell phone just dial (+ 52 1 and the 10 digit Mexican phone number. I am going to test this out over the next month and if it works out, I will drop my present Canadian plan. You can't beat $6.90/month Canadian price.
