English
An eSIM for Guam is a digital data plan for the phone you already own. There is no physical SIM card, no airport lines, and no passport needed. Your plan is ready on your SIMAREA account before you even leave home.
It works safely alongside your normal SIM. You keep your own number for calls and important text messages. Your data goes through the SIMAREA plan. Just turn off data roaming on your home SIM to avoid high bills.
Coverage comes from GTA Wireless, the one network these plans use. Your phone connects to it when you arrive.
If you stay longer, top up your current plan with more data. You do not need to buy a new one.
What it is not: a local phone number. If you need a number for verification codes, see virtual numbers.
Guam eSIM on GTA Wireless
Data for Tumon Bay, a dive week or a family stay, on GTA Wireless. The days start at the first connection in Guam, so you can install it at home.
The unlimited plan is the day pass we feature for Guam: after its daily full-speed allowance it keeps you connected at a lower speed, and it is billed per day for the days you choose. Fixed plans are one price for the term shown. Nothing on this page is an estimate.
How to get mobile data in Guam
Set it up at home the night before. Your eSIM waits quietly until you arrive.
Pick eSIM plan
Choose how long you are there. The day pass is billed per day, so the term is yours to set.
Pay, then scan
Charged from your balance, which you top up with crypto. Your QR code is in your dashboard once the order is paid.
Turn it on when you arrive
Turn on data roaming for your SIMAREA plan when you arrive, and it joins a partner network.
What to know about an eSIM for Guam
The specifics that decide whether a travel eSIM is useful once you're actually there.
Runs on GTA Wireless
Plans for Guam connect to GTA Wireless. Your phone joins it once data roaming is on for the eSIM.
Set up before you go
No SIM card store, no passport check. Install it at home, then turn on data roaming for it when you arrive.
Hotspot sharing
Share your internet with a laptop or a friend, if your plan and phone allow it.
Keep your own number
The eSIM is just for internet. Your normal SIM still receives calls and important bank codes. You can use both at once.
Keep using the same eSIM
Staying longer? Top up the same plan with more data from your dashboard. No need for a new QR code.
If it does not work
Not installed or connected yet? Ask for a refund within 30 days of buying it. Installed but not working on any of its networks? Support helps, and refunds you if it cannot be fixed.
A Guam eSIM, not a United States plan
Guam is a US territory, so it's tempting to think a US eSIM covers it. The United States plans on SIMAREA don't list Guam, so buy for Guam itself: every plan on this page connects to GTA Wireless, the one network they use.
The second surprise is the address. Each Guam plan sends its traffic out through Singapore, so your US bank, a streaming service or an online store sees a Singapore IP rather than an American one. An app that checks location may ask you to confirm a login or show what it offers in Singapore. If one matters to you, read the IP address row under Technical specs before paying.
Day pass or fixed data on GTA Wireless
The day pass gives 1 GB at full speed each day, then holds the eSIM at 1 Mbps until the day resets, which keeps messages and maps moving between beaches at a slower pace. The fixed plans are 1 GB for 7 days, 3 GB for 15 days, and 3, 5, 10 or 20 GB for 30 days.
A long weekend in Tumon fits the week; a month-long family visit is better on 10 or 20 GB, especially if you share the connection with a laptop, which works if your plan and phone allow it. Every plan tops up with more data on the same eSIM; the term stays as bought.
Flying on to Saipan, Manila or Tokyo
Guam plans are sold for Guam alone: Saipan, Tinian and Rota in the Northern Mariana Islands aren't part of them, and no regional or global plan adds Guam to a wider trip. If your ticket continues west, give the next stop its own eSIM, such as the Philippines, Japan or South Korea. Install it before you leave Guam; the Guam eSIM can stay on the phone for the flight home.
Guam eSIM questions
Does a United States eSIM work in Guam?
Not the SIMAREA United States plans: Guam isn't on them. What your own US carrier charges on the island is a question for that carrier.
Is the Guam day pass unlimited?
Only the slow part is open-ended. Each day starts with 1 GB at full speed; after that the eSIM continues at 1 Mbps until the day resets.
Can I get a Guam phone number?
Not with this eSIM. It handles data only, with no local number, no calls and no SMS, while your regular SIM keeps your number. For a number that receives SMS codes, see virtual numbers.
When should I install the Guam eSIM?
At home, before you fly. No plan here starts counting until it first connects to GTA Wireless in Guam, and an unused plan stays valid for 180 days. Keep in mind that an eSIM can be refunded on request only while it hasn't been installed or connected, within 30 days of purchase.
What if I stay longer than 30 days?
A top-up adds data to the plan you have, not more days. When the term ends, buy another Guam plan and install it the same way.
