Octotel fibre: Cape Town coverage, deals and cheapest ISPs (2026)

Octotel is the fibre network that quietly wired up much of Cape Town — and it tops the independent quality rankings. Here is where it reaches, what it costs across ISPs, and its standout multi-gig speeds.

Cape Town has more than one fibre network under its streets, and if you’re in the city or the peninsula there’s a strong chance one of your options is Octotel. It doesn’t market itself loudly, but it has a habit of topping the independent network-quality rankings — which, for the thing that carries your connection, matters more than the branding.

What Octotel actually is

Octotel is an open-access fibre network (an FNO) focused on greater Cape Town and the Western Cape. Like the other big networks, it builds and runs the line and wholesales it to ISPs — so you don’t buy "Octotel" directly; you pick an ISP (Afrihost, Webafrica, Cool Ideas, MWEB, RSAWEB, Vox) that sells over the Octotel line. It has been building since around 2015 and passes somewhere in the region of 360,000 homes and businesses.

Where Octotel reaches

This is a regional network, not a national one — and that focus is its strength. Its footprint spans the Cape Town metro and out into the Western Cape: Somerset West, Gordon’s Bay, Melkbosstrand, Kraaifontein, Wellington and more. Within its patch it’s dense and well-established. Outside the Western Cape, you won’t find it — that’s where Vumatel, Openserve or Frogfoot come in.

As always, the town isn’t the answer — your gate is. Check your exact address to see whether Octotel is live for you, alongside every other network that reaches you. There’s more on our Octotel network page.

The multi-gig party trick

One thing that sets Octotel apart from most networks: it doesn’t stop at gigabit. On supported ISPs you can get 2.5 Gbps and even 5 Gbps lines — genuinely future-proof speeds that most South African networks don’t offer at all. Realistically most homes never need more than 100–200 Mbps, but if you’re a heavy household or run a home business, it’s nice to know the ceiling is that high.

Octotel deals: who sells it cheapest

Same line, different bill — so shop the ISP. Because they all rent the same Octotel fibre, the gap at a given speed is mostly promos and margin. These were the lowest prices we were tracking on Octotel at the time of writing:

Line speedCheapest we track /mo
25/25 Mbpsfrom R499
100/100 Mbpsfrom R807
300/200 Mbpsfrom R895
500/200 Mbpsfrom R1 229
1000/200 Mbpsfrom R1 469
2500/2500 Mbpsfrom R2 099

Prices and promos change, so confirm the live figure before you order — but the takeaway holds: the network is fixed, the ISP is your lever. The fibre deals page ranks every ISP on your line by real monthly price.

The verdict

Octotel is a quietly excellent pick if you’re in its Cape footprint — top marks for reliability, symmetrical speeds, and a multi-gig ceiling almost no one else matches. In much of Cape Town it competes head-to-head with Vumatel and Frogfoot at your address, so the smart move is to check which are live and compare them on price. We do exactly that in SA fibre networks compared.
