Skyalo eSIM Data Plans for Guam

Skyalo does not provide an unlimited data eSIM for Guam.
The available options are fixed‑data plans: for example, the Guam • 20 GB • 30 days plan costs $83.99 USD and the Guam • 10 GB • 30 days plan costs $49.99 USD. Both plans include tethering capability and last for 30 days from the first network connection.

If a traveler needs more data, they may opt for a higher‑capacity plan, such as the global 20‑GB plans that also cover Guam, or purchase additional Pay‑as‑you‑go credit. Fixed data plans can be more cost‑effective for most users, while heavy data users can consider top‑ups or a higher‑cap plan.

Skyalo does not provide Guam eSIM plans that include a phone number or SMS service. Travelers who need messaging or calls over the local network will need to rely on data-only plans and use Internet‑based VoIP applications such as WhatsApp, Telegram, or iMessage. While these apps can generally be used over a Guam data connection, some destinations may block or restrict access to specific services, so travelers should confirm that their preferred apps are available in Guam before purchasing a plan.

Skyalo offers 15 single‑country data plans and 9 multi‑country data plans for Guam. The single‑country plans provide data caps ranging from 500 MB to 20 GB, prices from $7.47 to $199.50, and validity periods from 1 to 365 days. The multi‑country plans cover several destinations while offering a similar range of data and validity options; some include tethering and limited speed reductions for large data amounts.
