Which plan covers Guam?
The Guam plan. Guam is a US territory, but in our list it has a plan of its own, so choose Guam rather than the USA plan. The network it uses is shown live below, from our catalogue.
- Networks for GuamGTA Wireless
- Speed4G/LTE on this network.
- Internet runs viaSingaporeDepending on the plan. Banking or streaming apps may treat you as being there.
Tumon, the main hotel area, and the towns along the west coast are the strongest spots. Signal can be weaker on quiet roads in the south, in the jungle and on beaches that you reach on foot or by boat.
Coverage around the island
Where your phone stays online, and where to prepare:
- Tumon Bay: the hotel and shopping strip. Maps, translation and messaging work well here, though a busy evening can slow any network.
- Hagatna and the central towns: the capital and the towns around it are well covered, which helps if you drive yourself.
- Ritidian Point and the north: quiet and remote. Save the route offline before you drive up.
- The south (Umatac and Inarajan): a scenic coast road with villages and viewpoints. Signal can drop between the towns.
Renting a car? Download the Guam map in your map app before you leave the hotel. It takes a few minutes and saves data on the road.
Arriving at Guam airport
Antonio B. Won Pat International Airport (GUM) is a short drive from Tumon. Your eSIM is ready before the plane lands, so arrival takes four steps.
- Switch it on after landing
Once the plane has landed, leave airplane mode and turn data roaming on for the Guam line. Choose that line for mobile data and keep your home SIM for calls.
- Open your map app
Search for your hotel in Tumon or your rental car pick-up. A downloaded island map also works without a signal.
- Plan your ride
Hotel shuttles, taxis and rental car companies serve the airport. Keep your booking open on the phone.
