MobiMatter eSIM Data Plans for Guam

MobiMatter does not provide an unlimited‑data eSIM plan for Guam. All available plans for the island have finite data caps: 34 GB per year, 26 GB per year, 17 GB per year, 13 GB per year, and 5 GB for 30 days. The validity periods range from 30 days to 365 days, and the plans include features such as tethering.

Travelers who need a large data allowance can choose one of MobiMatter’s fixed‑data plans. For example, the APAC 34GB Yearly plan costs $69.99 USD for a full year and the Global 26GB plan costs $74.99 USD for the same period. These fixed plans can be more cost‑effective for most users unless the traveler expects extremely heavy data usage.

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 offers eight multi‑country eSIM plans for travelers heading to Guam, while no single‑country plans are available. These multi‑country options cover a price range from $9.99 to $74.99 and provide data caps between 1 GB and 34 GB, with validity periods that can span from one week up to a full year. The plans also allow tethering, enabling users to share data with other devices. The single‑country category remains empty for Guam, so all available selections fall under the multi‑country umbrella.
