Guam, this American gem lost in the western Pacific, mixes white-sand beaches, exceptional seabeds and authentic Chamorro culture. More than 13,000 km from Paris, this island and US territory welcomes thousands of travellers every year looking for a total change of scene. But between finding your way along the coastal roads of Tumon, looking for a dive spot at Two Lovers Point or coordinating with your hotel in Hagåtña, staying reachable is not optional. With a Simpartout eSIM activated before take-off, you avoid astronomical roaming fees and enjoy a 4G/LTE connection as soon as you set foot on the island.

Why is an eSIM essential in Guam?
Guam is a US territory, which means your usual European plans do not apply there and roaming fees can quickly become prohibitive. The island is well covered by 4G/LTE thanks to the local operators GTA TeleGuam, Docomo Pacific and IT&E, but buying a physical SIM on the spot means finding a shop, showing a passport and spending precious time on your first day. With an eSIM everything is sorted before you leave: you activate your plan from Paris, and as soon as you land at A.B. Won Pat International Airport you are connected. Handy for calling a taxi, checking Google Maps in the jungle of Ritidian Point or sharing your sunset photos in real time. The eSIM also frees you from dependence on hotel Wi-Fi, which is often overloaded in the tourist resorts of Tumon Bay.
