AdventureSIMs eSIM Data Plans for Guam

AdventureSIMs does not provide an unlimited data eSIM for Guam. The available plans are fixed‑data packages. For example, a 20GB plan valid for 30 days is priced at $77.51 USD, while a 10GB 30‑day plan costs $49.32 USD, and a 5GB 30‑day plan is available for $28.18 USD. These options may be more cost‑effective for most travelers unless they require truly unlimited usage.

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 does not provide any single‑country plans that cover Guam. However, there are five multi‑country plans that include Guam in their coverage. These plans generally span a price range from about $8.45 up to $77.51 and offer data caps between 1 GB and 20 GB, with validity periods from 7 to 30 days. Some of the multi‑country options also allow tethering.
