Maputo: As the capital, Maputo boasts the most reliable mobile network coverage in the country. You'll find strong 4G and LTE signals across the central Baixa, Polana, and Costa do Sol districts, particularly around hotels and business centers. Coverage remains consistent on public transport within the city, but can weaken inside older, thick-walled colonial buildings or in crowded markets like Mercado Central.

Beira: Connectivity in this key port city is generally good, with dependable 4G in the city center and along the beachfront. Service is focused on the commercial hub and main residential areas. However, signal strength can be less consistent in neighborhoods further from the center, and indoor coverage in large concrete structures may be intermittent.

Nampula: In the northern commercial hub of Nampula, you can expect solid 4G coverage within the central business district, known as the 'cidade de cimento'. As you move towards the city's periphery and into more sprawling residential zones, the network often switches to a still-functional 3G service. Main transport routes are well-covered, but service can be spotty deep inside large, enclosed market areas.

Pemba: This coastal gateway to the Quirimbas Archipelago offers good 4G connectivity in the main city area, especially around the port, airport, and the popular Wimbe Beach hotel strip. The connection is tailored for tourist activity, but it rapidly becomes less reliable and may drop to 2G or lose signal entirely as you travel to more remote coastal lodges or venture into the rural interior.

Inhambane & Tofo: The historic city of Inhambane has decent 3G and growing 4G coverage. In the nearby tourist hotspot of Tofo Beach, signal is generally strong enough for messaging and basic browsing along the main beach and in guesthouses. However, the connection can become strained during peak tourist season and may be weaker inside some of the more robustly-built dive centers or restaurants.

National Highways (EN1, EN4, EN6): Major routes like the north-south EN1 have consistent coverage near cities such as Maputo, Beira, and Nampula. However, expect very long stretches with weak or non-existent signal in rural areas, particularly through the vast expanses of Zambezia, Nampula, and Cabo Delgado provinces.

CFM Rail Corridors: On passenger and freight lines like the Sena Line (Beira-Moatize) or the Nacala Corridor, connectivity is generally limited to stations and the towns they serve. The majority of the journey through the Mozambican bush will be without a reliable mobile signal.

Western Highlands: When traveling in the mountainous areas along the border with Zimbabwe in Manica province, especially on roads branching off the EN6 corridor, signal can be intermittent to non-existent. Higher elevations and sparse population contribute to frequent network drops.

Major River Crossings: While long tunnels are not a feature of Mozambican roads, crossing major rivers on long bridges like the Armando Emilio Guebuza Bridge over the Zambezi can lead to a temporary loss of signal. Coverage usually resumes upon reaching the opposite bank and approaching a nearby town.

National Parks and Northern Interior: Vast regions, including the provinces of Niassa and interior Cabo Delgado, have extremely limited mobile infrastructure. Expect virtually no service inside national parks and reserves like Gorongosa National Park, Limpopo National Park, or the Niassa Special Reserve.
