Internet
$2/device/day. Use a rocket or other receiver to rebroadcast to the boat to save monies.
Reasonable speeds during the day, slow at night. Fairly consistent.
Skype for business worked well.
Voice
Verizon via Telcel: pretty bad. 4G until a call was made and then 3G took over for the call. The voice quality was like being underwater. *sigh*. No idea how well a telcel SIM would work.
Airport
Tiny. Make sure to give yourself at least 1 hour for the $320MXN cab ride to the airport.
