SimSwift eSIM Data Plans for Guam

SimSwift does not provide an unlimited data eSIM for Guam. The provider offers fixed data plans instead, such as the Guam 20GB 30Days plan for $63.99 USD and the Guam 10GB 30Days plan for $34.99 USD, both valid for 30 days and tied to a hard data cap. Choosing a fixed data plan can be more cost‑effective for most travelers, though very heavy data users may need to purchase additional data or consider a higher‑cap plan.

SimSwift does not provide eSIM plans for Guam that include a phone number or SMS capability. Only data‑only eSIM plans are offered for this destination.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to specific apps or VoIP services, so travelers should verify that the apps they rely on are accessible in Guam before purchasing.

SimSwift offers six single‑country data plans and seven multi‑country plans for Guam. The available plans span a price range from $9.49 to $141.99 and a data cap range from 1 GB to 20 GB, with validity periods varying from one week up to a full year. Some plans include tethering, and the two main product types are fixed‑data amount plans that provide a set data bundle for a set period, and daily‑data‑cap plans that offer a daily data limit.
