Guam: Mobile Coverage & Carriers
ESIMBYCOUNTRY at checkout · See all codes →Guam's mobile market is served by three carriers: GTA, Docomo Pacific, and IT&E. These operators provide 3G, 4G/LTE, and 5G services, though the exact commercial launch status of 5G should be verified. A roaming eSIM on Guam would likely connect using LTE bands B2 (1900 MHz) and B4 (AWS), or 5G band n78 (3.5 GHz) where available.
Some local carriers in Guam issue eSIMs to customers, though coverage of this service among all three operators is unclear due to limited confidence in available data. Travelers and new residents should verify directly with their chosen carrier regarding eSIM availability and supported network bands, as details remain limited.
