YeeSiM eSIM Data Plans for Guam

YeeSiM does not provide an unlimited data eSIM for Guam. The available options for Guam are fixed data plans, such as 20GB for 30 days at $91.00 USD, 10GB for 30 days at $53.00 USD, and 5GB for 30 days at $31.00 USD. These plans offer substantial data allowances and can be more cost‑effective for most travelers unless a user requires very high data usage that would be better served by an unlimited plan from a different provider.

YeeSiM does not provide a Guam eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are offered for Guam by YeeSiM. Travelers can still use VoIP services such as WhatsApp, Telegram, and iMessage over the data connection for voice calls and messaging, which do not require a local phone number or SMS.

YeeSiM provides 5 single‑country plans and 4 multi‑country plans for Guam. The available plans cover data amounts ranging from 1 GB to 20 GB and are priced between roughly $9 and $136. All listed options are fixed‑data plans, meaning the data allowance is set for the entire validity period and no daily data cap is indicated.
