Shikomor is the main language of many everyday conversations, while French is also widely used in daily and institutional settings and Arabic has official status. Under Loi 2014, state and private-institutional written communication uses Arabic and French simultaneously. Institutional titles use Classical Arabic and French. Bilingual French-Arabic staff are relevant for formal communication, and a translation and interpreting institute has been planned. Direct conversation, family and community mediation, voice calls, SMS and mobile data are common ways to communicate across the Comorian archipelago. No nationwide formal service for ordinary interpersonal disputes has been established; direct clarification or local mediation is the usual response, and its legal effect is not guaranteed. ANRTIC is the national telecommunications regulator. Relevant companies and networks include Comores Télécom, Yas Comores and Comores Cables. Mobile penetration exceeded 90% in 2021, while internet penetration was 28% in the same year. On 27 May 2025, 5G frequencies were assigned to Yas Comores and Comores Télécom. SIM cards and mobile plans are available through telecommunications companies and authorized sellers, including some postal offices; the applicable identification documents should be confirmed with the seller. Yas has published examples such as 250 KMF for 250 MB until midnight, 500 KMF for 1 GB for one day, 1,000 KMF for 2 GB for three days, 2,000 KMF for 4 GB for seven days, 5,000 KMF for 10 GB for 30 days, 10,000 KMF for 20 GB for 30 days and 25,000 KMF for 50 GB for 30 days. These are Yas prices, not a general market tariff. MVola, YasApp and USSD can support payments, account access and data use. La Poste Comores is the public postal provider, with more than 15 offices. It handles letters, parcels, EMS, tracking, registered mail, insurance, post-office boxes, mobile money and transfers. Postal services matter for inter-island and international communication. A post-office box normally uses a 12-month subscription and may require identification or authorization documents; opening, renewal and additional services can create extra charges. A tariff dated 19 June 2026 lists 250 KMF for a letter up to 20 g within the Comoros, 450 KMF for Zone 1, 500 KMF for Zone 2, 700 KMF for Zone 3 and 800 KMF for Zone 4. Zone 1 covers Réunion, Madagascar, Seychelles and Mauritius; Zone 2 covers France, French-speaking Africa, East Africa and Arab League states; Zone 3 covers Europe and non-French-speaking Africa; Zone 4 covers the Americas, Asia and Oceania. The Portail Gouvernemental and the Portail Unique du Citoyen are official entry points for online public services. ANADEN leads digitalisation and e-government work. Services and projects include passports, company formation, taxation, e-Bourse, e-Msomo and e-Shiyo, but a service appearing on a portal does not prove that the entire procedure can be completed online. Digital identity, data-centre and DNS capacity are still being developed. Loi 21-012 AU addresses cybercrime and the security of networks and information systems. Formal government communication may use ministries, e-government portals, postal services and telephone contact. The responsible ministry, island authority or institution should be identified for each matter because contact channels vary. No general online-only requirement is established. For a telecommunications problem, contact customer service first, then submit a written complaint to the company. If the matter remains unresolved, a complaint can be sent to ANRTIC online or by post at contact@anrtic.km, BP 750 Moroni, or +269 773 00 00. Complaints may concern tariff transparency, contractual service quality, privacy or data rights. Comoros accepted the Convention on the Rights of Persons with Disabilities through Law 13.12.2011, but a nationwide standard for accessible websites, captions, Braille, sign-language interpreting or relay communication has not been established. A 2023 report found that disability information was not consistently available in accessible formats. Personal contact, telephone, post or a trusted accompanying person can provide practical alternatives, but equivalent access is not guaranteed.
Communication in Comoros
Communication in Comoros uses Shikomor, also called Comorian, French and Arabic across face-to-face, telephone, postal and digital channels. Everyday exchanges mainly use Shikomor and French, while government and institutional documents use Arabic and French together. Telephone networks and postal services provide established channels, while online public services and accessible communication formats remain uneven. The suitable channel depends on language, island or institution, connectivity, delivery needs and whether a formal record is required.
Tip
Choose direct conversation or telephone for quick everyday matters, and use a written postal or digital channel when you need a traceable record. For formal institutions, confirm the responsible office and any Arabic-French document requirement instead of assuming that Shikomor, a portal listing or a local contact is sufficient. For telecom problems, keep evidence and escalate from the company to ANRTIC only when the company has not resolved the complaint.
