MoodSIM eSIM Data Plans for Guam

MoodSIM does not provide a truly unlimited high‑speed data eSIM for Guam. All plans that carry the “Unlimited” label in their name actually give a fixed amount of high‑speed data—such as 1 GB/day or 2 GB/day—after which the speed drops to a reduced rate (for example 512 kbps or 1 Mbps).

If you need more data without a daily cap, MoodSIM offers fixed‑data eSIMs for Guam. Examples include the 20 GB plan valid for 30 days at $52.49 USD and the 10 GB plan for 30 days at $27.99 USD. These plans give you a larger data allowance at a set price and may be more cost‑effective for heavier users.

MoodSIM does not provide Guam eSIM plans that include a phone number or SMS capability. Only data‑only eSIM options are available from this provider for Guam. Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though they should verify that these services are accessible in Guam before purchasing.

MoodSIM provides a total of 15 single‑country data plans for Guam, and an additional 9 multi‑country plans that include Guam as one of the covered destinations.

The plans vary in pricing from $4.99 to $90.49 USD and in data allowances ranging from 500 MB up to 20 GB, with validity periods between one day and a full year. The offering includes both fixed‑data plans—where a set amount of data is delivered for the duration of the plan—and daily‑data‑cap plans that reset every 24 hours. Many of the plans allow tethering, and some include conditional reduced speeds (512 kbps, 1 Mbps, or 384 kbps) as a way to manage congestion.
