Yes, it does indeed work (for SMS) in Mexico.
I just activated one of these (the 323 ebay sim, with the higher first-minute charge) a few days ago in the US. Got back to Mexico today, popped the SIM in and it (surprisingly!) registered OK, on Movistar. Sent and received SMS to/from Google Voice fine (in under ten seconds), and the billing shows the US rates (10c receive, 15c domestic send).
Outbound calls with it (in Mexico) tell me I have outgoing calls barred (which is reasonable, it's not supposed to even register here).
Incoming calls get intercepted with a voice message that says I'm unavailable and gives the option to send your caller-id phone number (or another number) as a text message to the phone - this works great, I get an SMS like "Please call +52... as they tried calling you on +132327..." a few seconds later.
Very useful for me, a single SMS contact number that works across US, Canada and Mexico - with voice calls in two of those countries.
Has anybody tried this US/Canada sim in any other countries? Maybe the SMS feature is enabled in a any roaming location?
