AdventureSIMs eSIM Data Plans for Guam

AdventureSIMs does not provide an unlimited data eSIM for Guam. All of the plans available for Guam are fixed‑data packages that range from 1GB for 7 days to 20GB for 30 days with the same 4G and 5G coverage across Guam and 117 additional countries.

If a traveler requires a larger data allocation, AdventureSIMs offers high‑capability options such as the 20GB 30‑day plan priced at $66.30 USD and the 10GB 30‑day plan priced at $42.19 USD. These fixed‑data plans can be more cost effective for most users unless the traveler is an extremely heavy data consumer who would need an unlimited plan.

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 offers five multi‑country data plans for Guam, with prices ranging from $7.23 to $66.30 and data caps between 1 GB and 20 GB. Validity periods span 7 to 30 days, and all plans allow tethering. No single‑country coverage plans are available.
