eSIMzio eSIM Data Plans for Guam

eSIMzio does not offer a truly unlimited data eSIM plan for Guam. All of its Guam offerings are fixed data plans that provide 2GB of high‑speed data per day, after which the speed is throttled to 1000kbps.
If a traveler needs a larger amount of data, eSIMzio’s fixed plans such as the Guam Unlimited — 7 days and Guam Unlimited — 10 days give a total of 14GB or 20GB at 2GB per day respectively, and can be more cost‑effective for most users unless they require constant, full‑speed data beyond the daily limit.

eSIMzio does not provide a Guam eSIM that includes a phone number or SMS capability. Only data‑only plans are offered for Guam. Travelers who need calls or messages can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, though some destinations may restrict or block access to particular apps or services, so it is advisable to check that the applications you rely on are available in Guam before purchasing.

eSIMzio provides four single‑country data plans for Guam, each featuring a daily data cap of 2 GB. No multi‑country plans are available from this provider. All of the plans are priced between roughly $21.64 and $75.74, giving customers a range of options in terms of validity (from 7 days up to 30 days) while maintaining the same data cap per day.
