Comoros eSIM

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.

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.

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.

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.

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.
