Micronesia eSIM
The Federated States of Micronesia is four quite different states — Yap, Chuuk, Pohnpei and Kosrae — strung out over a thousand kilometres, each with its own languages, customs and reason to visit, from wreck diving in Chuuk Lagoon to the stone city of Nan Madol on Pohnpei. Moving between them depends mainly on the Island Hopper, which operates only a few days a week, so sort out documents and how you will connect before you leave rather than on the way.

How much data you actually need
Most visitors keep their usage light: messages, email and checking flights, mostly over accommodation Wi-Fi in each state's main town. Prepare maps and documents offline, and assume that large uploads of dive footage will be something you do after the trip rather than each night from your room.
When you land
There are four gateways, one per state: Pohnpei International (PNI) near Kolonia, Chuuk (TKK) on Weno, Kosrae (KSA), and Yap International (YAP) at Colonia. All sit on the Island Hopper route that links Honolulu and Guam island by island. Outer islands such as Ulithi or the Mortlocks are reached on government ships and irregular light-aircraft services rather than anything you can book like a normal flight.
Where coverage changes
Workable service sits in each state's main town: Kolonia on Pohnpei, Weno in Chuuk Lagoon, Tofol on Kosrae and Colonia on Yap. Head out along the ring roads, into the interior rainforest on Pohnpei, or onto a boat crossing the lagoon, and it thins quickly. The outer islands of Yap and Chuuk, hundreds of kilometres away, should be treated as offline for the entire time you are there.
Cities travellers ask about
- Kolonia (Pohnpei) — Pohnpei's main town and the base for Nan Madol and the inland waterfalls.
- Weno — Chuuk's main island and the hub for the lagoon's wreck-diving operators.
- Colonia (Yap) — Yap's main town, close to the manta sites and the stone-money villages.
- Tofol — Kosrae's centre, a quiet green island with the ancient Lelu ruins.
- Nan Madol — Stone ruins on artificial islets off Pohnpei, visited with a local guide.
Apps to install before you fly
- Google Maps with each island you visit downloaded beforehand
- Facebook and Messenger, the channels dive shops and lodges actually answer on
- An airline app to follow the Island Hopper between states
- An email app that syncs first and stays readable with no signal

FAQ
Is there an eSIMonline plan for Micronesia?+
Not currently. The Federated States of Micronesia is not in our plan list, so please do not plan on buying one from us for Pohnpei or Chuuk. What we would suggest instead is asking your existing provider about roaming, using accommodation Wi-Fi, and preparing maps and documents offline. If the trip routes through Guam or Hawaii, plans for those destinations cover those legs normally.
Do the states have different rules about visiting sites?+
They differ noticeably. Many places, especially on Yap and around Nan Madol, are land or cultural sites cared for by a community, so visits go through a local guide or need permission arranged in advance, and some carry an access fee paid in cash. Ask your accommodation or operator first, and check each state's entry conditions with the official authorities before you travel, since they are not uniform across the country.
Will I be reachable during a full day diving Chuuk Lagoon?+
Mostly not. The boats leave Weno for wreck sites out in the lagoon, away from the settled shore, so signal is weak or gone for most of the day and returns when you come back in the evening. Answer anything urgent before boarding, tell people at home you will be quiet until nightfall, and keep the dive shop's schedule and number saved on the phone in case the plan changes mid-day.
When does a Micronesia eSIM start counting days?+
Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.
Do I have to remove my home SIM?+
No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
