eSIMCard eSIM Data Plans for Guam

No. eSIMCard’s plans that carry the name “Unlimited” actually provide a fixed amount of high‑speed data—1 GB for most single‑day and multi‑day options, or 2 GB for the “Plus” variants. Once that data is used, the speed drops to 512 kbps (or 2000 kbps for the Plus plans). If a traveler requires a larger continuous data allowance, eSIMCard offers fixed‑data plans such as 10 GB for 7 days ($153.46 USD) or 5 GB for 7 days ($85.47 USD). These options give a larger high‑speed allocation and can be more cost‑effective unless the user is an extremely heavy data consumer.

eSIMCard does not offer a Guam eSIM plan that includes a phone number or SMS capability. Only data‑only eSIMs are available for use in Guam through this provider. Travelers who need to make or receive voice or text messages can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that those services are accessible and not blocked in Guam before purchasing a plan.
