実際に必要なデータ量
A normal visitor here uses roughly 300MB–800MB a day, most of it messaging, maps and Portuguese translation. If you upload diving clips or video call home every evening, budget nearer 1.5GB a day instead.
到着後にすること
The main gateway is Sao Tome International (TMS), only a few kilometres from town, with flights arriving mainly from Lisbon, Accra and Libreville. Principe has its own strip, Principe Airport (PCP) at Santo Antonio, reached on a 35-minute hop in a small aircraft from Sao Tome. Switch the line on as you land, because guesthouse pickups here are usually confirmed by message rather than at an airport desk.
電波が変わる場所
Service is densest in Sao Tome town and along the northern and eastern coast road where the villages line up. It thins or disappears once you are inside the Obo rainforest in the island's middle, around Pico Cao Grande, on the run south to Porto Alegre and on the offshore islets such as Ilheu das Rolas. On Principe it clusters around Santo Antonio, while the southern coast and the forest walking routes have effectively nothing, so download the offline map before you leave town.
よく質問される都市
- Sao Tome: Bayside capital with Portuguese colonial buildings and the central market.
- Santo Antonio: Principe's main town, tiny and much quieter than the big island.
- Trindade: Hill town near the capital, on the way to waterfalls and old plantations.
- Neves: Northern port town, the launching point for dive and fishing boats.
- Porto Alegre: Far south end of the main island; long road in and patchy signal.
出発前にインストールしておきたいアプリ

よくある質問
Will data still work when I go over to Principe?+
It works in Santo Antonio and the larger villages, but along the southern coast, on the forest trails and at the beaches you reach by boat, you can be out of range for long stretches. Save your maps, your domestic flight details and your accommodation's number to the device before you take the small plane over from Sao Tome, and fix pickup times while you still have signal rather than assuming you can call from the other end.
Do I need Portuguese to get around on my own?+
You do not need to speak it, but you should carry a translation app. Outside hotels and tour operators, English does not go far, and agreeing a car price, asking directions or ordering in a small restaurant usually ends with you holding the screen out for the other person to read. Download the offline Portuguese pack too, because the places where you most need it are often exactly the places where the signal is weakest.
How do I get between the two islands, and what should I prepare?+
Most people fly: a small aircraft between Sao Tome and Principe takes about 35 minutes. Boats do run, but the schedule is unreliable and the crossing takes far longer. Guesthouses and the domestic airline often confirm by message or email rather than through a full online system, so screenshot every confirmation and keep it on the device, and leave slack in your plans because domestic hops can shift with the weather.
サントメ・プリンシペの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。
