Tips for Travelers in Guam
Make the most of your Guam trip with these connectivity tips from fellow travelers:
Download and install your AloOui Guam eSIM profile at home before departure. It won't activate until you land — so you're ready the moment you step off the plane at Antonio B. Won Pat International Airport.
Your AloOui eSIM runs alongside your existing SIM. Keep your home number for calls and WhatsApp while using the Guam eSIM for data — no need to choose.
Before heading to Ritidian Point, the northern jungle trails, or remote beaches, download offline maps on Google Maps or Maps.me. Even with unlimited data, offline maps save battery and load instantly in areas with weaker signal.
On the Unlimited Lite plan, enable Low Data Mode on your phone to stretch your 1GB daily full-speed quota further — great for beach days and sightseeing with light usage.
Guam's top experiences — scuba diving at Blue Hole, snorkelling at Fish Eye Marine Park, Chamorro Village night market, and War in the Pacific tours — can fill up fast. Use your AloOui data to book online the moment you arrive.
Whether you're exploring the southern villages, the northern highlands, or the resort strip in Tumon, your AloOui eSIM keeps you connected across the entire island without relying on hotel Wi-Fi.
For Business Travelers & Digital Nomads
Guam is a key hub for US military, government, and corporate travel in the Pacific — as well as a growing destination for remote workers and digital nomads. Here's why AloOui's Unlimited Plus is the go-to plan for professionals.
The Plus plan gives you network priority — so even in crowded resort areas, the airport, or busy Tumon business districts, your connection stays fast and stable.
Video calls, large file uploads, cloud syncing — 2GB of full-speed data per day keeps your workflow uninterrupted, with 2 Mbps fallback for lighter tasks.
Share your connection with your laptop or tablet. Perfect for working from a Tumon café, a hotel in Hagåtña, or a co-working space without relying on public Wi-Fi.
Extended stays covered. Whether you're on a month-long assignment or an extended Pacific trip, one plan keeps you connected the whole time.
Scan a QR code and you're online. No SIM procurement, no corporate roaming plans, no waiting at a carrier store. Instant activation means you're productive from day one.
One flat rate, no surprise roaming bills. Ideal for expense reporting and budget-conscious professionals who need reliable data without unpredictable carrier charges.
