iRoamly eSIM Data Plans for Guam

iRoamly does not provide a truly unlimited high‑speed data eSIM for Guam. The plans that carry “Unlimited” in the name actually offer 500GB of 5G data and reduce speed to 10000kbps after that threshold is reached.

As an alternative, iRoamly offers fixed‑data eSIMs for Guam, such as the 500GB 5G plan that gives high‑speed data for up to 500GB before throttling to the 10000kbps speed. These fixed‑data options can be more cost‑effective for travelers who do not need unrestricted data.

iRoamly does not offer a Guam eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are available for Guam.

Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which do not require a local phone number or SMS service.

iRoamly provides a mix of single‑country and multi‑country data packages in Guam. Customers can select from 18 single‑country plans that cover only Guam and from 112 multi‑country plans that include Guam along with other destinations. The available offerings span a broad pricing spectrum from free to $257 and a data cap ranging from 500 MB up to 500 GB. Plan structures vary between fixed data allocations and daily data caps, giving travelers the flexibility to choose a model that best matches their usage patterns.
