YonoSIM eSIM Data Plans for Guam

There is no unlimited data eSIM offered by YonoSIM for Guam. The available plans for Guam are fixed‑data bundles that include a 20GB and a 10GB option, each valid for 30 days, and a 10GB/day plan that is available for three days but comes with a reduced speed of 384 kbps. These fixed data plans can be more cost‑effective unless a traveler needs constant, unrestricted data usage.

YonoSIM does not offer a Guam eSIM plan that includes a local phone number or SMS capability. Only data‑only eSIMs are available for Guam. Travelers who want to make calls or send messages can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict access to these services, so it is advisable to verify that the apps you rely on are accessible in Guam before purchasing.

YonoSIM offers a substantial selection of data plans that cover Guam, including 69 single‐country options that are tailored exclusively to Guam and 20 multi‑country packages that include Guam as part of a broader regional offering. These plans differ mainly in the way data is allocated – some require a fixed data amount for the entire validity period, while others apply a daily data cap that allows moderate usage each day. Across all Guam‑available plans the prices range from about $5 to more than $1, 000, with data caps spanning from 500 MB up to 20 GB, and the validity periods extend from a few days to an entire year.
