ESIM888 eSIM Data Plans for Guam

ESIM888 does not provide an unlimited data eSIM for Guam.
Instead, ESIM888 offers several fixed‑data plans for Guam. The largest options are the 10GB plan valid for 30 days and the 5GB plan also valid for 30 days. Other choices include a 3GB bundle for 15 days, a 1GB bundle for 7 days, and a 1GB daily pass valid for two days. Selecting a fixed data plan can be more economical unless a traveler expects to use far more data than the allotted volume.

ESIM888 does not provide a Guam eSIM that includes a phone number or SMS capability; the provider sells only data‑only eSIM plans for Guam.
Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages, but these services may be restricted or blocked in Guam. It is advisable to verify that the apps you rely on are accessible before purchasing a plan.

ESIM888 offers eight single‑country data plans for Guam. There are no multi‑country packages available for this destination. Among the single‑country options, four plans provide a daily data cap, meaning the allotted data is refreshed each day of validity, while the remaining four plans offer a fixed data amount that is usable over the entire validity period. The available plans vary in price from about $4.40 to $37.05, with data allocations ranging between 1 GB and 10 GB and validity periods between 2 and 30 days.
