eSimFlare eSIM Data Plans for Guam

eSimFlare does not provide an unlimited data eSIM plan for Guam. All available plans list a specific data cap, such as 20GB for 30 days, 10GB for 30 days, or 5GB for 30 days. Travelers who need more data than a single plan offers can combine purchases or choose a higher‑cap option. Fixed data plans are typically more cost‑effective for most users unless their usage is exceptionally high.

eSimFlare does not offer a Guam eSIM that includes a phone number or SMS capability. The provider’s Guam plans are data‑only, so travelers have a data subscription without a local phone number. If voice or messaging is needed, apps that work over data, such as WhatsApp, Telegram, or iMessage, can be used instead.

eSimFlare supplies 38 single‑country data plans for Guam, with no multi‑country options available. The plans are divided between 28 daily data‑cap offerings and 10 fixed‑data plans, giving travelers flexibility in how they manage their usage. Prices across the portfolio range from roughly $4.74 to $522.85, while the data caps span from 500 MB up to 20 GB, providing a broad spectrum of choices for different travel needs.
