Sudafrica: la copertura

Cosa vogliono dire i numeri di Sudafrica

Contano due numeri e solo uno è quello che citano tutti. La velocità tipica, 42 Mbps, dice com'è un buon momento.

Il decimo percentile, 10 Mbps, è quello che vale la pena leggere. È la velocità nel decimo peggiore della giornata, quando la cella sopra la stazione è piena e tutti intorno a te ci sono dentro. Un paese con mediana alta e pavimento basso funziona benissimo, fino al momento in cui ti serve davvero.

Se il viaggio dipende da videochiamate o hotspot, pianifica sul dato delle ore di punta e non su quello tipico.

Cosa succede in Sudafrica quando la rete è congestionata

La congestione non è un guasto, è un martedì sera. La domanda è cosa può farci la tua eSIM, e per quasi tutte le eSIM da viaggio la risposta è niente: un accordo all'ingrosso per paese, una rete, e nessuna via d'uscita se non comprare una seconda eSIM da qualcun altro mentre sei in mezzo alla strada.

Qui il traffico Orbislo passa da Vodacom e MTN. Quando la rete su cui sei peggiora ti spostiamo su un'altra, a metà viaggio, senza che tu lo chieda, e te lo diciamo dopo invece di interromperti sul momento.

Sudafrica: operatori mobili

• Vodacom: Vodacom paid the most in South Africa's first spectrum auction in March 2022, R5.38 billion for 20 MHz at 700 MHz, 80 MHz at 2600 MHz and 10 MHz at 3500 MHz.
• MTN: MTN spent R5.15 billion in the March 2022 auction on 20 MHz at 800 MHz, 40 MHz at 2600 MHz and 40 MHz at 3500 MHz, the largest block of 3500 MHz spectrum any bidder bought at that sale.
• Telkom, rain, Cell C and Liquid: In the 2022 auction Telkom paid R2.11 billion for 20 MHz at 800 MHz and 22 MHz at 3500 MHz, and rain R1.43 billion for 20 MHz each at 700 and 2600 MHz. Cell C took 10 MHz and Liquid 4 MHz at 3500 MHz.
• Vodacom: Vodacom South Africa had 39.1 million prepaid and 7.0 million contract customers at 31 March 2026, and 28.2 million of the smart devices on its network were 4G or 5G capable.
• MTN: MTN South Africa ended 2025 with 40.6 million subscribers, of whom 29.7 million were prepaid and 4.6 million postpaid, and 22.0 million active data users.
• Cell C: Cell C began moving its customers onto rival networks in January 2021, contract and broadband customers to Vodacom and prepaid customers to MTN, while decommissioning its own towers over three years. A Cell C line largely rides on those two networks.
• rain: rain is a licensed mobile network operator running a national 4G and 5G network on its own spectrum at 700 MHz, 1800 MHz, 2600 MHz and 3600 MHz, alongside one of the country's largest 5G home internet networks.

Sudafrica: reti più vecchie

• Government had set 31 December 2027 as the deadline to switch off 2G and 3G, but in 2025 the communications department said it would no longer impose a date and would leave the timing to each operator, area by area.

Sudafrica: il 5G

• Vodacom launched mobile 5G on 4 May 2020 on 20 sites in Johannesburg, Pretoria and Cape Town, using 50 MHz of temporary 3.5 GHz spectrum that the regulator released during the COVID-19 state of disaster.
• rain launched what it calls Africa's first commercial standalone 5G network, built on a dedicated 5G core rather than on a 4G one.
• 5G reached 58.0 percent of South Africans in 2025, up from 46.6 percent a year earlier, according to operator returns collected by the regulator.
• Rural 5G is thin. In 2025 it reached 74 percent of rural Gauteng but only 7 percent of rural Eastern Cape and 13 percent of rural Northern Cape. Urban 5G ranged from 89 percent in the Western Cape to 38 percent in the Free State.

Sudafrica: note sulla rete

• In 2025, 3G reached 99.85 percent of the population and 4G 99.5 percent, but mobile broadband reached only 82.1 percent of the country's land area, so parts of the countryside have no mobile data signal at all.
• South Africa counted 117.3 million mobile subscriptions in September 2025, of which 96.5 million were prepaid and 20.8 million postpaid, with prepaid falling about 1 percent in the year.
• When four West African submarine cables, WACS, SAT-3, ACE and MainOne, failed on 14 March 2024, Vodacom blamed an undersea cable for disruption. The impact on South Africa was smaller than in most affected countries, which was credited to its nine submarine cables.
