aloSIM does not provide an unlimited data eSIM for Guam. The provider’s available options for the island are fixed data plans with caps of 5 GB, 3 GB, 2 GB, and 1 GB, each with a set validity period from 7 to 30 days. Travelers who need higher data usage might consider one of the larger fixed plans, such as the 5 GB 30‑day or 2 GB 15‑day offers, which can be more cost‑effective for moderate to heavy data consumption, but these do not provide unlimited data.
aloSIM does not provide any Guam eSIM plans that include a local phone number or SMS capability. The provider only offers data‑only eSIMs for Guam. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that those services are accessible in Guam before purchase.
