RedSim eSIM Data Plans for Guam

RedSim does not provide a plan that offers unlimited high‑speed data for Guam. The plans titled “Guam Unlimited” give 2 GB of high‑speed data each day; after that the speed is throttled to 512 kbps or 1 Mbps, so they are not truly unlimited.

Travelers who need a larger amount of data can choose fixed data plans, such as Guam 20 GB 30 days, Guam 10 GB 30 days, or Guam 5 GB 30 days. These bundles give a set amount of high‑speed data that must be used within 30 days and can be more cost‑effective for heavy data users.

RedSim does not provide a Guam eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are offered for Guam.

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 it is advisable to verify that the apps you rely on are accessible in Guam before purchasing a plan.

RedSim offers 10 single‑country data plans for Guam, with no multi‑country options available. The plans are divided evenly between daily data‑cap and fixed data‑cap types, five in each category. Prices range from roughly $8.06 to $69.59, and data caps span from 1 GB to 20 GB over validity periods of 3 to 30 days.
