MobiMatter eSIM Data Plans for Guam

MobiMatter does not provide an unlimited data eSIM for Guam. All of the plans listed for Guam have a specific data cap, the largest being 34 GB for the APAC 34 GB Yearly plan. Travelers who need a larger data allowance can choose from MobiMatter’s fixed‑data plans. For example, the APAC 34 GB Yearly plan offers 34 GB for 365 days and the Global 26 GB plan supplies 26 GB for the same period. Selecting a fixed‑data option can be more cost‑effective than paying for unlimited data, unless the traveler is a very heavy data user.

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 lists eight multi‑country data plans for Guam, priced from $9.99 to $74.99 and offering between 1 GB and 34 GB of data over validity periods ranging from seven to 365 days; tethering is allowed on all of them. No single‑country plans are available for Guam.
