Mexico's a nice place to travel to! I am seeing here that you have the Mobile w/o Borders feature included in your plan! 

The good thing about this is you have Unlimited calling and texting between the US, Mexico, and Canada. Mobile and landline numbers included.
Up to 5GB high-speed data allotment (or max of your high-speed data bucket if less than 5GB).
Includes both device data and mobile hotspot data usage.
If 5GB (or max high-speed data allotment) is exceeded, impacted lines reduce to speeds 128kbps
