eSIM Guam

Guam is a US territory in the Western Pacific and a major destination for Japanese and Korean tourists, with US standards of infrastructure and Japanese-influenced tourism facilities. GTA Wireless provides 4G and expanding 5G coverage across the island. Data is essential for navigating between Tumon Bay's resort strip, historic Hagåtña (Agana), and the southern villages, using standard US apps (Google Maps, Uber, Yelp) that all work normally here.

GTA's 4G covers the entire island comprehensively — Guam is only 548km² and coverage is essentially island-wide. Tumon Bay (the main resort area), Hagåtña, Dededo, Tamuning, and all 19 municipalities have solid connectivity. The Ritidian Point Wildlife Refuge at the northern tip has coverage. Two Lovers Point scenic overlook has coverage.

As a US territory, all standard US apps work without restriction or modification — there is no equivalent to the China situation. US data plans from American carriers also work in Guam (though this eSIM provides GTA local coverage). English is widely spoken alongside Chamorro.

Guam's WWII history sites — the Guam Museum, Pacific War National Historical Park, the Liberation Day route — are interesting and well-documented on Google Maps. The Cetti Bay Overlook on the south of the island and the road to Umatac Bay have coverage throughout.

Guam uses the US dollar. Standard US credit cards are universally accepted. The island is a free port with duty-free shopping. Japan Airlines, United, and Korea Air serve the main airport.
