Quick plan summary

• Coverage: Guam only, not Saipan or the Northern Mariana Islands.
• Fixed data: 1GB/7 days, 2GB/15 days or 3GB, 5GB, 10GB or 20GB/30 days. These are total allowances, not daily amounts.
• Daily Unlimited: Lite, Essential and Plus for 1, 3, 5, 7, 10 or 15 days. No Premium option is selectable; Plus is not Premium.
• Listed network: IT&E, supporting up to 5G where available. A blank brand field does not establish another partner.
• Data only: no local number, ordinary calls or SMS.
• Delivery and ID: QR code by email. No ID verification is required for the AloOui purchase; this does not waive local requirements.

Compare Guam packages

Lite/1 day is the lowest-priced selection, not a week-long package. Fixed data suits lighter maps, messages and bookings spread over a longer stay. For a three-day visit, Essential at $59.25 is the balanced daily option, providing 1GB high-speed each day followed by reduced-speed data for that day. Fixed 3GB/30 days at $63.65 lasts longer but provides 3GB total without reduced-speed continuation. Plus offers more high-speed data each day for heavier uploads or supported hotspot use. Match allowance, duration and total cost to your trip.

Prices may change. Always check the product page for the latest prices before purchasing.

How daily Unlimited works

• Lite: 1GB/day high-speed, then up to 512 kbps.
• Essential: 1GB/day high-speed, then up to 1.25 Mbps.
• Plus: 2GB/day high-speed, then up to 2 Mbps.

Standard Guam Unlimited options are Lite. Daily high-speed allowances refresh each day; reduced speeds apply for the rest of the day after that day's allowance is used. Unlimited does not mean unrestricted high-speed data. Fixed plans end when their total allowance or validity runs out, whichever comes first, without reduced-speed continuation. Actual speeds depend on connectivity and can be below policy limits. Daily packages stop at 15 days; longer fixed validity does not mean daily data. Larger allowances do not extend coverage.

Guam network and coverage

The Guam provider entry lists IT&E, supporting up to 5G where available. Its brand field is blank; this does not indicate a second partner. Confirm your exact option's entitlement if needed. Actual connection and speed depend on your purchased plan, device, location and local conditions. Neither 5G nor reception at every beach, property or address is guaranteed.

Beaches, remote routes and restricted locations

Save maps, tickets and accommodation details offline before leaving reliable coverage. Confirm essential locations with support before purchasing, particularly remote northern or southern areas, Ritidian, trails or specific accommodation. A Guam coverage entry does not independently establish reception at every attraction or military installation.

Check current access, permissions, weather and local safety guidance separately. A data plan does not grant access to restricted locations. Arrange appropriate backup communications for remote travel rather than relying on continuous mobile data for navigation or emergencies. Satellite and maritime networks are not included, and reception throughout boat trips is not promised. A cellular eSIM is not an underwater communications solution.

Hotspot and data-only service

Hotspot depends on your selected plan, device and network; confirm exact-option terms if sharing is essential. Shared usage counts toward the same total or daily high-speed allowance and speed limits. Large uploads, backups and streaming can use data quickly.

This eSIM has no local number, ordinary calls or SMS. Internet-based messaging and calling depend on app availability and connectivity. If keeping your home SIM enabled on a compatible device, check its roaming charges, turn off its data roaming and avoid automatic data switching.

Compatibility, installation and activation

1. Check that your exact device model and regional version support eSIM and that the device is carrier-unlocked.
2. Install the emailed QR code over stable Wi-Fi through your cellular or SIM settings, following your order's instructions. Keep the QR private.
3. When ready in supported Guam coverage, enable AloOui, select it for mobile data and turn on its data roaming as instructed.

Validity starts when the eSIM connects to a supported network in Guam, not QR delivery or installation alone. Enabling the line within supported coverage can start the plan. Follow your purchased option's activation deadline, expiry and top-up instructions.

APN, connection help and 24/7 human support

1. Check AloOui is enabled, selected for mobile data and has data roaming on as instructed.
2. If manual APN setup is needed, enter data.esim with username and password blank, then save/select it. Follow your order if its settings differ.
3. After installation finishes, toggle airplane mode briefly or restart. Try 4G/LTE if 5G is unstable.
4. Start with automatic network selection. If needed, select IT&E as confirmed in your order or by support and move to a stronger-signal area when safe.
5. Check remaining data and validity. Keep the eSIM installed while troubleshooting.

Ask support before deleting the profile, changing devices or rescanning the QR code; do not assume transfer, reinstallation or QR reuse is supported.

AloOui provides 24/7 human customer support through the Help Center. Share your order number, exact device model, location and error privately.
