AloOui eSIM Data Plans for Guam

AloOui does not provide a completely unlimited data plan for Guam. Instead, the provider sells fixed‑data plans that allow up to 1 GB per day of high‑speed data, after which the speed is throttled to a lower rate (512 kbps for the “Lite” packages or 1.25 Mbps for the “Essential” packages). For example, the Guam eSIM Unlimited Lite 1GB/day then 512 kbps 1 Day plan costs $18.57 USD and is valid for one day, while the Guam eSIM Unlimited Essential 1GB/day then 1.25 Mbps 1 Day plan costs $22.29 USD with the same validity. A higher‑capacity option is the Guam eSIM Unlimited Plus 2GB/day then 2 Mbps 1 Day plan, priced at $44.58 USD for one day. These alternatives offer substantial data allowances but are not truly unlimited in the sense of unlimited speed.

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.
