eSIMzio eSIM Data Plans for Guam

eSIMzio does not provide a true unlimited data eSIM for Guam. The plans listed under the “Guam Unlimited” banner actually grant a hard limit of 2GB per day; after that threshold the speed is throttled to 1000kbps. These are fixed data plans rather than unlimited plans.

For travelers who need more data, eSIMzio offers fixed data plans that accumulate a larger total allowance over their validity period. For example, the 30‑day plan supplies 2GB per day, amounting to 60GB of high‑speed data, while the 7‑day plan provides 14GB of such data. These alternatives can be more cost‑effective for most users, unless a very heavy data usage is anticipated.

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.
