MobiMatter eSIM Data Plans for Guam

MobiMatter does not offer an unlimited‑data eSIM plan for Guam. The provider sells fixed‑data plans instead. One of the largest options is the APAC 34 GB Yearly plan, priced at $69.99 USD with a validity of 365 days; another is the Global 26 GB plan, $74.99 USD, also 365 days. These high‑data plans can be more cost‑effective for most travelers, though very heavy data users might seek alternative solutions.

MobiMatter does not provide Guam eSIM plans that include a phone number or SMS capability. The available plans are data‑only, so travelers will not be able to receive or send traditional SMS messages or make voice calls via the eSIM. However, they can use popular VoIP applications such as WhatsApp, Telegram, or iMessage to communicate over the data connection, which offers an alternative way to call and message while traveling.

MobiMatter’s catalogue for Guam contains 10 multi‑country eSIM plans, while there are no single‑country offerings for this destination. The multi‑country plans span a price range from about $9.99 to $74.99, with data caps between 1 GB and 34 GB and validity periods from 7 to 365 days. Some of these plans support tethering, allowing you to share data with other devices. The plans are primarily fixed‑data packages rather than daily‑cap options, giving travelers a set amount of data for the duration of the validity period.
