YeeSiM eSIM Data Plans for Guam

YeeSiM does not provide an unlimited data eSIM option for Guam. The available plans for Guam are fixed‑data packages, the largest of which is a 20GB eSIM that is valid for 30 days and priced at $91.00 USD. Other larger allowances include a 10GB plan for $53.00 USD and a 5GB plan for $31.00 USD, each also valid for 30 days. These plans are unrestricted for tethering but do not offer unlimited data.

Choosing a fixed data plan can be more economical, especially for travelers who do not need an unlimited data allowance. If a user requires very high data usage, a fixed plan with a higher data cap may still offer the best value compared to a standard unlimited plan, which YeeSiM does not supply for Guam.

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.
