AdventureSIMs eSIM Data Plans for Guam

AdventureSIMs does not currently offer an unlimited data eSIM for Guam. The provider lists fixed data plans ranging from 1GB for 7 days up to 20GB for 30 days. Each plan gives high‑speed 5G access across Guam and a network of 117 additional countries. Travelers needing substantial data may consider the 20GB or 10GB options, which can be more cost‑effective for high‑usage users, but a true unlimited plan is not available.

AdventureSIMs does not provide a Guam eSIM that includes a phone number or SMS capability. The available Guam eSIM plans are strictly data‑only, so there is no inbound or outbound voice or SMS service included.

Travelers who need to communicate can use the data connection to run VoIP applications such as WhatsApp, Telegram or iMessage, which allow calls and messaging without a traditional phone number.

AdventureSIMs provides five multi‑country data plans that include coverage in Guam, and there are no single‑country plans specific to Guam.
The available plans span a price range of roughly $9.96 to $86.86 USD and offer data caps between 1 GB and 20 GB, with validity periods from 7 to 30 days. Some of the plans also permit tethering, allowing the data to be shared across devices.
