Mexico sounds fun to me right about now. We always want you to have a working phone especially during your travels. Let's provide you with options. What is the make and model of your device?
I understand that you don't want to have any extra costs, however our TravelPass is wonderful. It is only $5/day in Mexico and Canada. TravelPass lets you take your talk, text and data with you to more than 185 countries for a low daily rate.
