Guam travel data eSIM
What is a Guam eSIM?
Guam is a U.S. territory in the western Pacific, serving as a gateway to Micronesia. Travellers heading to Hagåtña or the Tumon resort area often need immediate connectivity for navigation and bookings. A dedicated eSIM provides data-only access upon arrival, allowing you to bypass local SIM hunting. It installs via QR code before departure, ensuring your device is ready to connect the moment you land at the airport.
This plan connects to GTA Wireless 4G networks within Guam. The validity period begins only when your device first connects to a local network at your destination. You select a data allowance ranging from 1GB to 20GB, with durations of either 7 or 30 days. This setup suits short stays or longer visits, providing consistent data access for maps, messaging, and web browsing while you explore the island.

Which networks you connect to in Guam
The Guam eSIM connects to GTA Wireless 4G infrastructure. Actual network availability depends on the operator's physical presence in your specific location on the island. As you move between Hagåtña and other areas, your device will link to the available GTA Wireless nodes. This ensures you maintain data access for essential travel tasks without needing to change physical SIM cards or rely on hotel Wi-Fi.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which operator does the Guam eSIM use?
The plan connects to GTA Wireless 4G networks. This means your device links directly to this local provider for data services. You do not need to find a physical SIM card or visit a store to activate service upon arrival in the territory.
Does this eSIM work in nearby Micronesia?
No, this is a single-country plan valid only in Guam. If you are travelling to other parts of Micronesia or the Pacific region, look for our multi-country regional plans that include multiple destinations in one data package.
Which plan size suits a trip to Hagåtña and Tumon?
As a rough guide, a 3GB or 5GB plan often suffices for a standard stay involving maps and messaging. For heavy streaming or multiple users, consider the 10GB or 20GB options to ensure you have enough data.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
