Insider tips

  • Public Wi‑Fi is available at hotels and cafes but can be slow or unsecured — use your eSIM for safer, more reliable access.
  • Renting a car is the easiest way to explore Guam — use your eSIM for GPS navigation and traffic updates.
  • Typhoon season runs June–November; check forecasts before travel. Peak tourist seasons are summer and major U.S. holidays.
