TraveleSIM.CH eSIM Data Plans for Guam

TraveleSIM.CH does not provide an unlimited data eSIM for Guam. All available Guam‑specific plans are fixed‑data offers, the largest of which is a 20GB plan valid for 30 days at a price of $53.89 USD. A smaller 10GB plan for 30 days costs $29.83 USD.

Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user expects to consume far more data than the plan cap. The 20GB and 10GB options cover typical usage and provide coverage exclusively in Guam.

TraveleSIM.CH does not offer a Guam eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are available from this provider for Guam. Travelers who need to make calls or send messages can use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection; however, some destinations may block or restrict certain apps or VoIP services, so it is advisable to confirm that the apps you rely on will work in Guam before purchasing a plan.

The available plans provide between 1 GB and 20 GB of data, and the price points range from roughly $4.81 to $89.16 USD. Validity periods vary from 7 days to 365 days, and the catalog includes both fixed‑data bundles and plans that apply daily data caps where relevant.
