I am traveling to Mexico from the U.S. for an extended period of time. I have Verizon and was looking for the best plan. I'll do mostly texting, some eMail, and not much talking. I know when traveling to Canada, my Verizon service transferred to Telus when I got to Vancouver, but I do not know what happens with the tele in Mexico near Playa Mujeres... does Verizon switch over to TelCel? Also, did/does anyone ever have any service issues while in the Cancun area?
