Yesim does not have an unlimited data eSIM plan for Guam. All of its listed offerings for that destination have a specific data cap and a 30‑day validity period.
Travelers who need more data can choose one of the available fixed data plans, such as the 10GB plan for about $56.08 USD or the 5GB plan for about $33.65 USD. These higher‑capacity options may be more cost‑effective for most users, though very heavy data users might still prefer a plan with a larger allowance or consider a pay‑as‑you‑go option if available.
Yesim does not offer an eSIM for Guam that includes a phone number or SMS capability. Customers can purchase a data‑only eSIM plan, but the plan does not support inbound or outbound voice calls or text messages.
Travelers who need to stay in touch can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that the apps they rely on are accessible in Guam before buying a plan, as some destinations may block or restrict certain services.
