AlpineSIM eSIM Data Plans for Guam

AlpineSIM does not offer a true unlimited‑data eSIM for Guam. The plans that carry the word “Unlimited” in their name actually provide a fixed daily data allowance, such as 1 GB or 500 MB. Once the allotted amount is exhausted, the plan ends and no further high‑speed data is included.

Travelers looking for larger data pools can choose one of AlpineSIM’s fixed‑data plans. For example, a 20 GB plan valid for 30 days costs $49.86, and a 10 GB plan for the same validity period costs $31.02. These options allow the user to access a substantial amount of data at a predictable price, which can be more cost‑effective than purchasing a series of smaller daily plans for heavy use.

AlpineSIM does not offer any Guam eSIM plans that include a phone number or SMS capability. The available Guam eSIMs from AlpineSIM are data‑only plans. Travelers who need voice or text can use VoIP and messaging applications such as WhatsApp, Telegram, or iMessage over the data connection instead.

AlpineSIM offers a single‑country data plan for Guam. The plan is priced between roughly $3.59 and $30.00 USD and provides between 500 MB and 5 GB of data for its validity period (up to 365 days). No multi‑country plans are specifically available for Guam.
