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 provides 69 single‑country data plans for Guam. The plans span a price range of $4.99 to $719.99 and a data cap range of 500 MB to 20 GB, giving travelers a wide range of options for data usage over validity periods from 3 to 365 days. The offerings include both daily‑data‑cap and fixed‑data‑cap styles, allowing travelers to choose the structure that best fits their needs.
