Comoros eSIM
The Comoros is a three-island volcanic archipelago in the Mozambique Channel, and a single trip usually means hopping between islands by small plane or boat on schedules that shift with the wind and the sea state. That is where your own data earns its keep: reconfirming a boat, an inter-island flight and a room again on the morning of travel. Almost everyone here communicates over WhatsApp rather than email or an online booking system, and official websites are rarely current.

How much data you actually need
Roughly 300MB–1GB a day covers WhatsApp, maps and photos. If you upload dive or snorkelling clips each evening, or tether a travel companion, budget nearer 1.5–2GB a day.
When you land
Prince Said Ibrahim International (HAH), north of Moroni on Grande Comore, is the main gateway, with domestic flights into Ouani on Anjouan (AJN) and Mohéli (NWA). By sea, Mutsamudu on Anjouan is the principal port, and passenger boats run between Moroni, Mutsamudu and Fomboni depending on conditions. Switch the line on when you land, since guesthouses usually collect guests themselves and will want to call you.
Where coverage changes
Moroni, Mutsamudu, Fomboni and most coastal villages work normally. It thins noticeably on the climb up Mount Karthala, across the interior plateau of Anjouan, in the forest and around the southern islets of Mohéli near Nioumachoua, and during boat crossings, which can lose service the whole way. Download the island maps in advance, because signposting is close to non-existent.
Cities travellers ask about
- Moroni — Capital on Grande Comore, with an old medina and a working fishing harbour.
- Mutsamudu — Anjouan's main port town, with narrow lanes and an old seafront citadel.
- Fomboni — Mohéli's main town and the base for the marine conservation area.
- Mitsamiouli — Beach area at the north end of Grande Comore, popular for snorkelling.
- Mount Karthala — Active volcano; the overnight climb has to be planned offline.
Apps to install before you fly
- WhatsApp, which guesthouses, guides and boatmen answer faster than email
- Google Maps or Maps.me with all three islands saved offline
- Google Translate with offline French and Arabic packs

FAQ
How far ahead should I book inter-island travel?+
Book ahead if you can, but always reconfirm on the day. Domestic hops use small aircraft and shift their times often, and the inter-island boats depend mostly on the sea state. What works is collecting a WhatsApp number for the airline or boat operator on your first day and checking status each morning before you set out. Always leave a spare day before your international flight home.
What language is spoken in the Comoros?+
Everyday conversation happens in Comorian, which is close to Swahili, while French and Arabic are also official. In practice French will get you through with guesthouses, shops and officials almost everywhere. You will meet some English at places used to foreign guests, but do not count on it, so download the offline French pack before you head out of town.
Should I carry cash or can I pay by card?+
Plan around cash. Shops, markets, boatmen and small guesthouses deal in Comorian francs, card payment exists only at a handful of larger hotels in Moroni, and ATMs are limited and do not accept every foreign card. Change money while you are still in Moroni, before you cross to Anjouan or Mohéli, where your options narrow considerably.
When does a Comoros 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.
