イエメンのeSIM

No. We do not carry a plan that covers Yemen, and we will not point you at a broad Middle East bundle as if it did. Check the country list of any plan you are about to buy, and if Yemen is not named in it, it will not work there. If you want to talk it through first, we are on LINE at https://lin.ee/skDPoNx (@esimonline) and at esimonline.asia@gmail.com.

During the southwest monsoon, roughly June to September, the wind is strong enough that cargo boats from the mainland stop and flight schedules become unreliable. Most operators run trips between October and May instead. If you travel near the edge of the season, build spare days into the plan, because a flight slipping by several days is normal here rather than exceptional.

Yes, and it is not something a traveller can file alone. A licensed operator has to obtain it from whichever authority controls the area you are entering, and because different parts of the country are under different administrations, a Socotra approval does not cover the mainland. Get written confirmation from your operator before you buy a ticket, not after.

Agree with people at home in advance that contact will come in bursts rather than daily, and send your message when you pass back through Hadibo or another spot with service. Guides usually carry a local line and will let you send a short message. Groups going into remote areas for several days often carry a rented satellite communicator for emergencies.

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。
