eSIM for Micronesia
The Federated States of Micronesia has limited 4G in main island towns only, with no signal on most of its 600+ islands. No mainstream travel eSIM provider covers it — a local SIM from the state operator is the only option on each island.

Weno (Chuuk island, main hub) has basic 4G on FSM Telecom. Palikir (Pohnpei, FSM capital) has reasonable coverage in town. Kolonia (Pohnpei) has good coverage for a Pacific micro-state. Yap has basic coverage in Colonia. Dive boats to the Chuuk Lagoon wrecks go offshore — completely offline during dives. Download dive site charts, ship manifests and dive briefing information in Weno before any liveaboard trip.
Chuuk Lagoon holds the world's most extraordinary collection of WWII wrecks — the Fujikawa Maru, Sankisan Maru, Shinkoku Maru and 60+ other Japanese vessels sunk during Operation Hailstone (February 1944) lie at recreational diving depths. Download offline dive site charts, ship plans and wreck histories before boarding any liveaboard. Most wreck dives are at 15–40m depth.

eSIM — Micronesia
Network coverage in Micronesia
FSMTC (FSM Telecommunications Corporation) is the sole mobile operator across the Federated States of Micronesia. Coverage is limited to the four main state islands — Pohnpei, Chuuk, Yap and Kosrae — while the remaining 600+ islands have no mobile signal. 4G/LTE is available in main towns (Kolonia on Pohnpei, Weno on Chuuk, Colonia on Yap, Tofol on Kosrae); most roads and rural areas operate on 3G. 4G speeds are slower than international averages and congestion during evening peak hours is documented. No 5G is available. At the main tourist sites — Nan Madol (Pohnpei), the Truk Lagoon wrecks (Chuuk), Yap's dive sites, Kosrae's ruins — connectivity is limited to the nearby town areas.
FSMTC has limited international roaming agreements, so many foreign home SIM cards will not connect in FSM. Since FSMTC is the only network, every option runs on the same towers with identical coverage: an FSMTC eSIM (now offered directly) or a local FSMTC prepaid SIM. The choice comes down to price and convenience, not coverage — a local FSMTC SIM is usually cheapest.

Arrival protocol in Micronesia
VPN, passwords and documents
On hotel or café Wi-Fi, a VPN can be useful to keep your browsing private from the network operator. A password manager is also worth having for managing account access on the road. A secure cloud backup of your passport, visa and accommodation details can also be useful — keep an offline copy too. None of these are mandatory.
