eSIM Guam

You need an eSIM-compatible, carrier-unlocked phone or tablet. Recent iPhones (XS and newer), Pixel phones and modern Samsung Galaxy models are common examples, but the full list is longer. Run your device through the eSIM compatibility checker if you're unsure.

1 GB suits short visits that lean on Wi-Fi, and 20 GB covers longer stays or heavier mobile use. Plans start at €15.99. There are currently 5 plans for Guam. Fixed GB plans are valid for 30 days. Validity begins when the bundle actually starts, not when you buy it.

Your Guam data bundle has three start options. Start automatically is selected by default. The bundle starts the first time My eSIM connects to a supported local network in Guam, and your validity period begins then. Schedule a start date lets you choose a future date or time. Keep the eSIM data line switched off until then, because connecting earlier can start the bundle sooner. Your account shows the real start moment. Start now activates the bundle immediately. Use it when you are already in Guam or need data straight away. Installing My eSIM does not start the bundle on its own, and buying the bundle does not start its validity. Validity begins when the bundle actually starts. You can change the choice in your account until that happens. Whether you're staying in one city or moving between islands, Start automatically is the simplest choice when you want the bundle to begin the moment your phone attaches to a local network in Guam.

Install My eSIM once, before you travel, on stable Wi-Fi or your home mobile internet. Installing My eSIM is separate from starting your Guam data bundle. The bundle only starts when you choose it to (see the activation options). On arrival in Guam, set My eSIM as your mobile-data line. If the setup instructions ask, enable data roaming on the eSIM line. That controls the eSIM line, not your home SIM. Keep mobile-data roaming disabled on your home SIM so your home carrier doesn't charge for data, but leave the home SIM in the phone for calls and SMS. Whether you're staying in one city or moving between islands, having My eSIM installed before you leave means you're online the moment you land in Oceania. My eSIM stays installed for future trips and additional data purchases. There's no new QR code to scan and no reinstall when you buy more data.

Yes. Every eligible eSIMbundle plan includes the VPN at no extra cost. Connect through the VPN app on your phone, tablet or laptop when you want to encrypt your traffic on local mobile networks or public Wi-Fi. It adds privacy for logins, payments, browsing and messaging on networks you don't control. VPN access becomes available once your Guam data bundle starts. The VPN doesn't switch on automatically just because My eSIM connected. The website dashboard only manages your VPN account; you can't establish the connection from the dashboard. In Guam, local carriers and public Wi-Fi at hotels, airports and cafés see more of your connection than your home network does. Turning the VPN on adds privacy on those networks.

Most everyday apps run normally in Guam. Public Wi-Fi at hotels, airports and cafés is a common weak spot for accounts and payments, and banking and payment apps can trigger extra checks when they see a foreign login. Your data bundle gives you your own mobile data, and the included VPN, turned on in the app, encrypts traffic on local carriers and public Wi-Fi.

Destination data bundles are data-only. WhatsApp, FaceTime, iMessage, Telegram and similar apps run over the eSIM data. WhatsApp keeps using your existing number because it's tied to your phone number, not the SIM currently carrying data. Keep your home SIM in the phone for calls and SMS, but disable mobile-data roaming on the home SIM so your home carrier doesn't start charging for data. Typical examples travellers rely on: hotel check-in messages and reservation reminders. Your home carrier may still charge for normal roaming calls or SMS on the home line. Using the destination data bundle doesn't replace your home phone number. In Guam, banking and login SMS still arrive on your home number as usual, so keep the home SIM available even if you rarely use it for calls.

Run out of data in Guam? You can add more data by buying another Guam destination data bundle from your account or from the Guam plans page. The new bundle attaches to My eSIM. No reinstall is needed and no new QR code to scan. Your account combines the available Guam data into one balance. Each purchase keeps its own start date and expiry, so new data doesn't extend older data. Whether you're staying in one city or moving between islands, this is straightforward: add data during your trip and keep using the same My eSIM. Additional fixed-GB bundles are what's on offer, and each keeps its own 30-day validity from the point it starts. When you add more data over an unfamiliar or public network in Guam, you can turn on the VPN app if you want to encrypt your connection.
