You can’t really “choose” a fibre network in South Africa the way you choose an ISP, because the cable already in your street decides that for you. But knowing who the big network operators are, and what each is known for, helps the whole thing make a lot more sense.
First, the bit everyone gets confused about: FNO vs ISP
There are two very different companies behind your fibre line, and South African marketing does a great job of blurring them. The first is the fibre network operator (FNO), the business that physically trenches the cable past your home and lights it up. The second is your internet service provider (ISP), the brand you actually pay each month.
Most of our networks are open-access. That means the FNO owns the cable but doesn’t sell directly to you; instead, lots of ISPs rent capacity on that same line and compete for your business. The upshot is simple and a little freeing: on a given line, every ISP delivers the same speed, because it’s the same physical fibre. You’re really choosing between support, billing, router and price, not between fast and slow. We unpack that trade-off in our guide to the best fibre deals in South Africa.
Worth getting straight: the FNO is set by your address. The ISP is your choice. So ask “which network reaches my home?” first, then “which ISP on it is best value?”
The big four networks you’ll meet most often
Four operators show up at the majority of homes that have fibre today. They overlap in the big metros and diverge sharply once you head into smaller towns or particular provinces. Here’s what each is genuinely known for.
Vumatel
Vumatel is the largest open-access network in the country, with more than two million homes passed. It’s strongest in the major metros (Johannesburg, Cape Town, Durban and Pretoria) and has pushed hard into township rollout under its Vuma Reach brand. It’s part of the broader Maziv group and offers speeds up to around 1 Gbps. If you’re in a leafy suburb or a well-established complex, there’s a good chance Vumatel is one of your options.
Openserve
Openserve is Telkom’s wholesale network, and its superpower is reach. It has the widest national footprint of the lot, roughly 1.5 million homes, and it’s often the one network that turns up in smaller towns where the others haven’t bothered to dig. Speeds run up to around 1 Gbps. If you live outside the big four metros and you have fibre at all, there’s a fair chance it’s Openserve under the road.
Frogfoot
Frogfoot, owned by Vox, is a nationwide operator with around 400,000 homes passed and a reputation for symmetrical packages, where your upload speed matches your download. That’s a quiet but real advantage if you work from home, back up to the cloud, or push large files. Speeds go up to roughly 1 Gbps.
Octotel
Octotel is the Western Cape specialist, covering Cape Town plus the Garden Route and the Overberg. It’s the network to watch if you care about raw speed: in select areas it offers multi-gig packages up to around 5–10 Gbps, well beyond what most homes will ever use. If you’re house-hunting in the Cape, our fibre in Cape Town guide goes deeper on who covers which suburbs.
The big four, side by side
A quick reference, though treat the “homes passed” figures as ballpark, since every network is still trenching new streets all the time.
| Network | Owner / group | Where it’s strong | Homes passed (approx.) | Top speed | Known for |
|---|---|---|---|---|---|
| Vumatel | Maziv | Jhb, CPT, Durban, Pretoria + townships | 2M+ | Up to ~1 Gbps | Biggest open-access footprint |
| Openserve | Telkom | Nationwide, incl. smaller towns | ~1.5M | Up to ~1 Gbps | Widest reach beyond the metros |
| Frogfoot | Vox | Nationwide | ~400K | Up to ~1 Gbps | Symmetrical (matching upload) plans |
| Octotel | Independent | Western Cape, Garden Route, Overberg | Western Cape focus | Up to ~5–10 Gbps (select areas) | Multi-gig speeds |
You’ll notice no “winner” column, and that’s deliberate. None of these is universally best; they’re best for the areas they cover. You can see the full list and where each reaches on our networks page.
The other networks worth knowing
Beyond the big four, a handful of operators round out the map and may well be the network at your door.
- MetroFibre (MetroFibre Networx): Gauteng-led but now spanning several provinces, with around 510,000 homes passed and speeds up to roughly 1 Gbps.
- Vodacom Fibre: mostly resells on existing open-access networks rather than running its own everywhere, often bundled with mobile, and it holds a stake in the Maziv group.
- Link Africa: an independent open-access network across Johannesburg, Durban and Cape Town, frequently the operator inside estates, complexes and underserved pockets.
- Lightstruck: a township and emerging-metro operator across Gauteng, KwaZulu-Natal and the Western Cape, with speeds up to around 500 Mbps.
This is also why two neighbours can end up on completely different networks: estate developers, body corporates and rollout timing all play a part. Whichever one reaches you, the ISPs riding it are listed on our providers page.
Speeds and prices: more alike than you’d think
Here’s the reassuring bit. Most of the big networks top out at a similar place, roughly 1 Gbps, and pricing for the same speed tends to land in similar bands regardless of which network carries it. The multi-gig tiers (looking at you, Octotel) are the exception, and honestly more than most homes will ever need.
As a rough guide across the market, uncapped fibre starts from around R400 a month for an entry-level line near 25 Mbps. A solid 100 Mbps plan tends to run roughly R600–R950, and a full 1 Gbps line lands somewhere around R1,200–R1,600. These are ballparks, not quotes; your actual price depends on the network at your home and the ISP you pick. Our cost-of-fibre guide breaks the numbers down further.
Speed reality check: a single 4K stream needs only about 25 Mbps. Most homes are genuinely happy on 50–100 Mbps, so the network’s headline gigabit number matters far less than whether it reaches you at all. If fibre doesn’t reach you, our fibre vs LTE comparison is the next stop.
So which network should you pick? Your address already did
This is the part that trips people up. You can’t shop for a network the way you shop for a phone. The networks roll out street by street, so the question “is Vumatel better than Frogfoot?” is a bit like asking whether the N1 is better than the N3. It only matters which one actually goes where you are.
What you genuinely control is the ISP. Once you know which FNO covers your home, you compare the providers on that line for real monthly price, router and support, and because the line is open-access, you can switch ISP later without re-trenching anything. That’s where the real saving lives, and it’s exactly what our best-deals guide is built to help with.
You don’t pick the network. The cable in your street does. What you pick is the ISP that rides it best.
So don’t guess. Pop your address into FibreScout and we’ll show you exactly which networks reach your home and which ISPs you can pick from. Plain options, no sales call, just the real choices at your door.
