I've got a Verizon cell phone that will work in the Roo but I would have to buy a SIM chip and then load it with Telcel time... from what it looks like it would cost about $10-15 U.S. for the chip and $10-15 U.S. for some time. However Verizon is $.99 a min.... so is it really worth getting the local sim? Maybe for data?
Also, my father has an old non-gsm phone, so his won't work. Does anyone know how much it would cost to by a cheap (cheapest) phone at an OXXO or Walmart or some place like that?
