YonoSIM eSIM Data Plans for Guam

YonoSIM does not provide an unlimited data eSIM for Guam. All Guam‑specific offerings from YonoSIM have a capped data allowance, with the largest plan giving 20 GB of data for a 30‑day period.

Travelers who need more data can choose a fixed‑cap plan instead. For example, YonoSIM offers a Guam 20GB 30Days plan priced at $72.99 USD and a Global (120+ areas) 20GB 30Days plan at $94.99 USD. These fixed plans may be a more cost‑effective option for most travelers unless they are very heavy data users.

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 15 single‑country data plans for Guam, all of which are fixed‑data packages. The plans provide data amounts ranging from 500 MB to 20 GB and are priced between roughly $3.74 and $94.99, with validity periods that can extend up to 365 days. No multi‑country plans that include Guam are currently available.
