iRoamly eSIM Data Plans for Guam

iRoamly does not offer a truly unlimited high‑speed data plan for Guam. All plans that carry the word “Unlimited” in their name actually have a data cap of 500GB; once that threshold is reached, the connection speed is reduced to 10, 000 kbps.

If a larger data allocation is acceptable, iRoamly provides fixed‑data eSIMs that cover Guam, such as the 500GB plan valid for 30 days at $209.00 USD. These fixed plans may be more cost‑effective for travelers who do not need unlimited high‑speed data, but they will experience a speed drop after the 500GB limit is reached.

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 offers 18 single‑country plans for Guam and 114 multi‑country plans that include Guam. The available plans range in price from $0 to $257 and in data allowance from 500 MB up to 500 GB. To accommodate different travel styles, iRoamly provides both daily‑cap plans and fixed‑data plans, allowing users to choose either a daily data limit or a one‑time data allocation for the plan’s validity period.
