Frequently Asked Questions
Do I need an international plan since Guam is a US territory?
US carriers typically don't charge roaming in Guam, but speeds may be throttled. An eSIM ensures consistent high-speed data and often costs less than US carrier daily passes.
Will my eSIM work on military bases?
Coverage is available near Andersen AFB and Naval Base Guam perimeters. Inside the bases, coverage varies due to security restrictions. Check with base communications for specific areas.
Can I use my Guam eSIM in nearby islands?
Guam-specific plans only work in Guam. For trips to Saipan, Palau, or other Micronesian islands, you'll need a Pacific regional package or separate plans.
How's coverage for diving and water activities?
Beach areas and dive shops have good coverage. Obviously no signal underwater, but boats typically maintain coverage in coastal waters. Download dive site maps before heading out.
