Before you go
Make your Guam plan work for you.
For light use, start with maps and messages in mind. Video calls, streaming, and uploads use more data. Choose a package that covers your full stay, then review when its validity starts in checkout.
Will this plan cover Guam?
The packages on this page list Guam as their single destination. Review the selected package in checkout for its coverage and activation details.
Can I keep my usual number?
An eSIM data package does not replace your existing number. Keep your primary SIM configured for calls and texts as needed. Your home carrier may charge for roaming calls or messages.
When should I install it?
Install with a reliable internet connection. Validity start rules can vary, so review the selected package instructions before installation or activation.
Will it work on my phone?
You need an unlocked, eSIM-compatible device. Support can vary by model, purchase region, and carrier. Confirm compatibility before paying.
Continuing beyond Guam?
These collections include Guam in at least one coverage option. Check the country list for your exact package.
