iRoamly eSIM Data Plans for Guam

iRoamly does not provide an unlimited data eSIM for Guam. All of its plans for Guam have a hard data cap. For example, the Global‑72 Countries‑eSIM‑90GB‑365 Days‑Total plan offers 90GB of data for 365 days, while the Global‑72 Countries‑eSIM‑60GB‑365 Days‑Total plan offers 60GB for the same period. There are also shorter‑term options such as the Saipan & Guam‑eSIM‑50GB‑3 Days‑Total, Saipan & Guam‑eSIM‑50GB‑5 Days‑Total, and Saipan & Guam‑eSIM‑50GB‑7 Days‑Total plans, each providing 50GB of data for 3, 5, or 7 days respectively.

Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would benefit from an unlimited plan. The 50GB plans include a speed reduction to 128kbps after the 50GB threshold is reached.

iRoamly does not offer a Guam eSIM that includes a phone number or SMS capability. The provider’s Guam plans are data‑only, with no built‑in voice or SMS services.

You can still use services such as WhatsApp, Telegram, or iMessage through the data connection, although some destinations may restrict access to certain VoIP applications, so travelers should confirm that the apps they need will work in Guam before purchasing.

iRoamly offers 18 single‑country data plans and 104 multi‑country plans that include Guam. Among these, 70 plans feature daily data caps and 52 plan for a fixed data amount, allowing customers to choose between a set amount of data for the entire validity or a daily cap that resets each day. Prices for Guam‑covered plans range from free to about $257 USD, while the data caps offered span from 500 MB up to 90 GB. Some plans also allow tethering, are available only to new users, and may include speed reductions of 384 kbit/s or 128 kbit/s in certain circumstances.
