I know this subject has been posted so many times. I have searched and I just keep getting more confused. I know not to phone from the hotel. I know to phone from a payphone. I phoned our phone company here and they said to go to Wal Mart and buy a international phone card. I saw 2 different types at Wal Mart, sorry, can't remember what the names where. Has anyone had any experience buying a phone card here in Canada and then using it in Mexico? Thanks for all your useful advise, fellow "Tripadvisors". The postings on this site have provided me with a wealth of useful information.
