MobiMatter eSIM Data Plans for Guam

MobiMatter does not have an unlimited data eSIM plan for Guam. All of the plans that specify Guam coverage have a fixed data allowance, ranging from 12GB on a 30‑day plan to 34GB on a 365‑day plan. For example, the APAC 34GB Yearly plan provides 34GB of data for 365 days at a price of $69.99 USD, while the Global 26GB plan offers 26GB for 365 days at $74.99 USD.

Travelers looking for broad data usage can choose one of these fixed‑data options. Selecting a larger data plan can be more economical for heavy users, but if an extremely high data consumption is expected, unlimited plans from other providers might be considered.

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.
