You should always set up your numbers with the + sign, followed by country code and number so they will work anywhere (such as +12125551212 or +491722222222). It's true, by omitting the GSM-standard plus sign, they might not work in Mexico, but that's no guarantee they won't call something else instead.

You are probably correct. I never tried making a call when the phone roamed to Mexico. This area has a number of hiking trails and cliffs. My bigger fear was not being able to make a call in the US if we were inadvertently set to roaming. FYI, our carrier is Verizon.

I did state there was little danger of an inadvertent "outgoing call". An inbound roaming call is probably more likely.
