Esimatic eSIM Data Plans for Guam

Esimatic does not provide an unlimited data eSIM plan for Guam. All available plans list a specific data cap, the largest being 50GB for 90 days. Travelers who need all the data they use in one month can instead choose one of Esimatic’s fixed plans. For example, the Guam‑only plan offers 20GB for 30 days at $174.90 USD, while the Global‑Standard plan gives 20GB for 30 days at $147.89 USD. These fixed‑data options can be more economical unless a very heavy data user requires an unlimited plan.

Esimatic does not offer Guam eSIMs that provide a phone number or SMS capability. The provider’s Guam eSIM catalog consists solely of data‑only plans. Travelers can still make voice calls and send messages by using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

Esimatic lists 23 single‑country plans and 22 multi‑country plans for Guam. The plans cover a price range from approximately $7.49 to $325.10 and data caps between 1 GB and 50 GB. Some options are fixed‑data packages that give a set amount of data for the entire validity period, while others use a daily‑data‑cap model that limits the amount of data you can use each day, letting travelers choose the plan that best matches their usage pattern.
