Portuguese is Mozambique's official language, while national languages receive state protection. Emakhuwa is the most common home language. In 2017, 47.4% of people aged five and above reported knowledge of Portuguese, compared with 78.1% in urban areas and 31.7% in rural areas. When people do not share a language, a trusted intermediary or language support may be needed. Mozambique has no documented nationwide etiquette or misunderstanding protocol, so clear wording, confirmation and culturally appropriate language remain practical safeguards. Mobile communication is the dominant formal channel. Tmcel, Vodacom and Movitel provide voice calls, SMS, mobile data and mobile financial services. By 2026, 4G expansion and 5G licensing were underway. National roaming can help in areas where only one network or a weak network is available. An indicative 2024 estimate counted about 17 million active mobile users and coverage of about 85% of the territory, but availability and service quality remain uneven, especially in rural areas. A SIM card requires registration under Decreto 13/2023. The process uses a valid identity document and biometric data and takes place through an authorised agent with validation before activation. Packages and prices depend on the provider and the selected service, so current tariffs, data allowances and coverage should be checked before purchase. A phone number or data package may work well in one area and poorly in another. Postal communication has an established but fragmented structure. The INCM portal lists 59 licensed providers. CORRE - Correio Expresso de Moçambique, S.A. is identified as the formal universal-service provider under Resolução 22/2024, while an older INCM consumer page still refers to Correios de Moçambique in liquidation. The provider should therefore be confirmed before sending an item. Universal postal services cover letters and publications up to 2 kg and parcels up to 20 kg, including registered and declared-value services. Standard national delivery to the destination office usually takes about three to five working days and may take up to five working days. Postal codes follow the revised Decreto 74/2024, and prices depend on the provider and service. Digital communication is formally established but fragmented in practice. Internet use was 7.8% nationally in 2017, with 17.8% in urban areas and 2.6% in rural areas. An in-person or offline alternative can therefore remain necessary for a public service, payment or document exchange. INAGE, IP coordinates e-government and digital citizen services and has provincial delegations outside Maputo. INTIC and SCDM support digital signatures under Lei 3/2017 and Decreto 3/2019. A certified digital signature can provide authenticity and integrity and may have legal effect according to the type of certification. Devices, connectivity and data costs depend on the market and the provider. The Ministry of Communications and Digital Transformation sets policy. INCM regulates and supervises telecommunications and postal services, including licences, numbering, spectrum and consumer matters. INAGE handles e-government coordination, while INTIC covers digital governance and certification. Users should receive transparent contract and tariff information, suitable service quality, data protection and access to complaint and dispute procedures. The relevant framework includes Decreto 73/2025 on consumer protection, Decreto 74/2025 on dispute resolution and Resolução 2/2026 on opt-in and opt-out controls. Lei 10/2024 recognises access to information, technology and communication systems through universal design and reasonable accommodation. Public and private providers are expected to offer accessible formats, and the state is expected to train communicators and officials in sign language. Braille, sign language and accessible emergency information are included in the legal framework. Decreto 73/2025 also calls for physically and digitally accessible customer channels, particularly for people with disabilities, although implementation is not uniform and no complete nationwide availability measurement is documented. A communication complaint normally starts with the relevant provider's customer service. If the issue remains unresolved, the user can use the INCM consumer portal or the free Linha do Cliente 1789, followed by the dispute-resolution process under Decreto 74/2025 where applicable. Keeping contracts, receipts, messages, reference numbers, delivery evidence and complaint dates supports the case. In 2025, postal providers recorded 258 complaints and resolved all of them; about 85.6% concerned delivery times. Telecommunications providers recorded 391,723 complaints and resolved 372,846, or 95.2%. The main reported problems included service quality, incorrect or unauthorised billing and activation without consent, while reported satisfaction was 82%.
Communication in Mozambique
Communication in Mozambique relies mainly on direct conversation and mobile services, while formal communication usually uses Portuguese. Local languages remain central in daily life, and access differs sharply between urban and rural areas. Mobile networks, postal services, digital channels and in-person contact each cover different needs and have different limits.
Tip
Choose the communication channel according to coverage, language, urgency, formality and accessibility rather than relying on one service. Check mobile access and costs before depending on a phone or data connection, and keep an in-person or offline option for services that may fail outside urban areas. Preserve proof of messages, payments, deliveries and complaints whenever the communication has legal, financial or practical consequences.
