Best eSIM for Americans visiting Mexico — Cancún, Tulum and beyond

9 October 2026·Proost eSIM

Mexico is one of the most visited destinations for American travellers

Cancún's beaches, Tulum's cenotes and ruins, and Mexico City's food scene draw huge numbers of US visitors every year. AT&T, Verizon and T-Mobile roaming in Mexico all carry daily or add-on fees that add up fast over a week-long beach holiday.

Mexico's mobile coverage

Mexico has solid 4G coverage across the main tourist areas — Cancún, Playa del Carmen, Tulum, Cabo and Mexico City all have strong signal. More remote areas of the Yucatán or Baja can be patchier.

How much data for Mexico?

  • 3GB — one week, light use (maps, messaging, occasional Instagram)
  • 5GB — two weeks, regular social media use
  • 10GB — heavy users or longer trips
  • The AUD price advantage for Americans

    Proost prices all plans in Australian dollars. At current exchange rates, roughly $10 AUD costs about $6.50 USD — meaningful savings compared to buying the same data from a US-based provider or through carrier roaming.

    Australian Consumer Law protection

    All Proost purchases are covered by Australian Consumer Law regardless of where you live — a real, enforceable consumer guarantee, not just a policy on paper.
