If you're getting it expressly for the purpose of using it in Mexico, would you consider other options instead? I'm sure this conversation has been beat to death here and on the Cozumel facebook pages, but it might be worth banging away at it some more.
I got a Charles Schwab debit card - yes, I had to open an account first (did it entirely online and it was easy peasy), and I had to transfer the money into the Schwab account at least 4 days before I needed to have access to it. You can install the Schwab app on your phone, which allows you to turn the debit card on and off, so if it's lost or stolen you can turn it off immediately. Or like me, you can turn it off right after you pull money out of the account. I use the HSBC machine at Chedraui to get pesos and, because so many nice people told me to do it, I say "NO" to the question at the end when they ask if I want them to do the conversion for me - so I get a more favorable conversion rate. Also, Schwab covers all the ATM fees.
I have often found that when I look at the pesos price on items and ask for the dollars price, the dollars price converts to more pesos than is listed on the items - at the airport I got a silver chain and paid in pesos when the price would have been $3 more in US dollars.
I know a few of you are rolling your eyes and saying "this conversation again?", but the title of the thread sounded like it was going to be related to dollars/pesos and cash/credit card. I couldn't help myself. Mea culpa.
