MobiMatter eSIM Data Plans for Guam

MobiMatter does not provide an unlimited data eSIM for Guam. The available plans are fixed‑data packages, some of which offer large allowances. For example, the APAC 34 GB Yearly plan gives 34 GB of data for 365 days at $69.99 USD, and the Global 26 GB plan offers 26 GB for the same duration at $74.99 USD. A shorter‑term option is the APAC 12 GB plan, which delivers 12 GB over 30 days for $22.99 USD. These plans all allow tethering and cover Guam plus multiple other countries. Choosing a fixed‑data plan can be more cost‑effective unless a traveler expects extremely heavy data use.

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 10 multi‑country data plans that include Guam. The plans cover a price range of $9.99 to $74.99 and data caps ranging from 1 GB to 34 GB, with validity periods of 7 to 365 days. Some of these plans allow tethering.
