Spark Roam eSIM Data Plans for Guam

Spark Roam does not provide an unlimited data eSIM plan for Guam. Travelers who need high‑capacity data can select from fixed plans such as the 20 GB / 30 days plan priced at $75.00 USD or the 10 GB / 30 days plan priced at $42.50 USD, both of which include coverage in Guam and 126 additional countries. Choosing a fixed data plan can be more cost‑effective unless you are an extremely heavy data user who would otherwise exceed the allotted data.

Spark Roam does not provide a Guam eSIM that includes a phone number or SMS capability. The provider only offers data‑only plans for Guam, so users must rely on VoIP services such as WhatsApp, Telegram, or iMessage to make calls and send messages over the data connection.

Spark Roam offers seven multi‑country data plans for Guam and no single‑country plans. The available plans vary in price from about $5.75 to $83.12, with data caps ranging from 1 GB to 20 GB and validity periods between 7 and 365 days. The plans typically provide a fixed data amount for the entire validity period rather than a daily data cap.
