AloOui eSIM Data Plans for Guam

AloOui does not provide a truly unlimited data eSIM for Guam. The plans listed as “Unlimited” are capped at either 1GB per day or 2GB per day, after which the speed is throttled to 512 kbps or 2 Mbps respectively.

If a fixed data allowance is acceptable, AloOui offers several high‑cap options. For example, the Guam eSIM Unlimited Plus plan gives 2GB per day for 1 day to 15 days, and the Guam eSIM Unlimited Lite plan provides 1GB per day for 1 day to 15 days. These plans use 5G and are valid for the specified number of days.

No, AloOui does not offer a Guam eSIM that includes a phone number or SMS capability. The only plans sold for Guam are data‑only, so travelers will not receive an active telephone number for inbound or outbound voice or text messages.

To stay in contact, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Because some destinations can block or restrict particular apps or VoIP services, guests should confirm that the applications they depend on work in Guam before purchasing a plan.

AloOui lists 24 single‑country data plans and 25 multi‑country data plans for Guam, together offering a price range from about $18.57 to $493.26. The plans cover data caps that span from 1 GB to 50 GB and vary in validity from one day to up to 90 days. Some of the 27 daily‑cap plans provide data on a per‑day basis, while the 22 fixed‑cap plans give a set amount of data for the total validity period.
