実際に必要なデータ量
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.
到着後にすること
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.
電波が変わる場所
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.

よくある質問
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.
ミクロネシアのeSIMは何日目からカウントが始まりますか?+
多くのプランは、スマホが現地のネットワークに最初に接続した時点から開始するため、自宅で事前にインストールしておき、到着後にオンにすることができます。各プランページにそれぞれのルールを記載しています。
自国のSIMを取り外す必要はありますか?+
いいえ。eSIMは2回線目として機能するため、SMS認証などには自国の番号をそのまま使えます。自国回線のローミングデータをオフにし、eSIMをデータ回線に設定してください。
