At Los Toros in Purificación we could get cell signals when we were high and clear enough to get a view of the coastal plain. Last Christmas we took some local teenagers down to Zaragoza for a New Year party as we were leaving for home. They all had cell phones and knew right where the signals were. In fact I've seen locals with cell phones walking around in the woods in Purificación for years. When I ask if they can get a signal, they say it depends on where you are. I used to wonder why they had phones - how could they afford them and who would they call? Then I learned that most have relatives working in Victoria or elsewhere who supply the phones. Note that for cell phones from the U. S. to work in Mexico you may have to sign up for extended coverage and/or pay exorbitant fees.

As for satellite phones, we had one at J2 in Oaxaca in 2004 and 2006. J2 base camp is pretty remote on a mountain top under very tall trees in a cloud forest, but we could get a signal in the right spots. In 2004 we used it to send daily dispatches to National Geographic, one of our sponsors.

I've had a reliable signal sitting at the table inside the sheet-metal

signal sitting in the outhouse. NexTel, TelMex, and MovieStar all have
signals up there now.
