1. Taxi & transport
Uber
A global ride-hailing app operating in Guam, letting you get around major tourist spots without a rental car.
- Covers all of Guam: operates in major areas like Tumon Bay, Tam Park, Agana (Hagåtña), and Coco Palms
- Airport pickup: request an Uber at Antonio B. Won Pat International Airport (GUM)
- Fare transparency: shows an estimated fare before you leave, with automatic credit card payment
- An alternative to Guam taxis: Guam's regular taxis can be expensive, so Uber is recommended instead
- Tip: Guam has almost no public transit, so a rental car or Uber/hotel shuttle is essential. Many hotels offer a shuttle service, so check with yours first.

💡 Tip: Guam has almost no public transit. A rental car is essentially essential. There are many Korean-specific rental car agencies (Roomroom, Tourvis, and more) — compare before booking.
2. Rental car
Essential rental car guide
A rental car isn't optional for a Guam trip — it's essential. Public buses are very limited, and major attractions are scattered across the island, making travel inconvenient without one.
- Global agencies: SIXT, Hertz, Budget, Avis, Enterprise, Alamo, and more operate counters at the airport
- Korean-specific agencies: agencies like Roomroom Car, Tourvis, and RentACar offer Korean-language support and KakaoTalk consultation
- Documents needed: a Korean driver's license plus an International Driving Permit (required) — get the international permit issued in advance in Korea
- Vehicle insurance: as a US territory, local insurance rules apply — CDW (Collision Damage Waiver) and LDW coverage are recommended
- Fueling: Guam uses US-style gallons for fuel. Gas stations include E-Mart, SHELL, 76, and more
- Tip: booking online or through a Korean agency in advance is cheaper than the airport counter. Book ahead during peak season, since cars can sell out early.
3. Maps & navigation
Google Maps
Provides maps across Guam, rental car navigation, and attraction information.
- Offline saving: save the entire Guam map in advance to save data and stay covered in areas with no signal
- Rental car navigation: use voice guidance for hands-free navigation
- Attraction info: locations for Tumon Bay, Chamorro Village, Gun Beach, Fiesta Resort, Inarajan Natural Pool, and more
- Finding dining: use Google reviews to explore local eateries, Korean restaurants, buffets, and steak houses
- Gas station search: find a nearby gas station before returning your rental car
- Tip: north Guam (Ritidian Point) and south Guam (Merizo Pier, Inarajan) have narrow roads and can have unreliable signal, so saving maps offline matters especially there.

4. Translation
Google Translate
Guam is a US territory where English is the official language, but local Chamorro culture and language are also present. Korean travelers are common, so Korean is understood in many places too.
- Korean↔English: communicate with local restaurants and activity operators
- Chamorro reference: Chamorro words can appear on local menus and signs
- Camera translation: translate English menus and signs
- Tip: Guam gets a huge number of Korean tourists, so more locals and businesses speak Korean than you'd expect.

Why an eSIM matters for a Guam trip
Guam is a US territory, but Korean roaming rates there are expensive. Rental car navigation (Google Maps), checking Klook tickets, finding restaurants, and hotel check-in all require data. A local SIM is available for purchase at the airport, but installing an eSIM from home in advance lets you start using rental car navigation the moment you arrive, which is far more convenient.
