Fibre in South Africa is cheaper than most people think — if you know where to look and you’re not fussy about speed. The rock-bottom lines start under R250 a month, and even proper uncapped 100 Mbps can come in around R600. Here’s what the cheapest end of the market actually looks like right now.
The cheapest fibre lines we track
These are the lowest prices we were seeing at the time of writing. They shift with promos, and — crucially — not all of them will be available at your address, but they show how low the floor really is:
| What you get | From /mo |
|---|---|
| Cheapest of all — 20/10 Mbps prepaid (Herotel Flex) | R199 |
| Cheapest uncapped monthly — 15/15 Mbps | R229 |
| Entry uncapped — 10 Mbps | from R307 |
| 50 Mbps uncapped | from R495 |
| 100 Mbps uncapped | from R605 |
| 200 Mbps uncapped | from R720 |
| 1 Gbps uncapped | from R775 |
A couple of those deserve a double-take. A gigabit line from around R775 is genuinely remarkable — a few years ago that was multiple-thousands-of-rand territory. And a fully uncapped connection for R229 is cheaper than most people’s monthly airtime.
How to actually get fibre cheaply
Four levers do most of the work:
1. Go prepaid or entry-tier. Prepaid fibre (like Herotel’s Flex) and starter lines skip debit orders and drop the price hard. Perfect if your usage is light or your budget is variable.
2. Look at the affordable-access networks. Products built for value — Vuma Reach, Zoom and similar — routinely undercut the premium metro lines while still being real uncapped fibre.
3. Shop the ISP, not just the network. This is the big one people miss. Several ISPs rent the same line, so the identical speed can cost R100+ more from one than the next. Our fibre deals page ranks every ISP on your line by real monthly price — that spread is free money.
4. Don’t overbuy speed. Most homes run comfortably on 25–50 Mbps. Paying for 200 Mbps you never use is the most common way people overspend on fibre. Match the speed to the household, not the marketing.
Cheapest isn’t always the smartest buy
A fair warning: the very cheapest line isn’t automatically the right one. Rock-bottom plans can mean lower speeds, a weaker upload, or an ISP with a patchier support record — and on a bad connection, the money you saved stops feeling like a saving. It’s worth checking the ISP’s customer ratings alongside the price, not just chasing the lowest number. Sometimes R50 more a month buys a noticeably better experience.
Is affordable fibre actually any good?
People often assume affordable fibre means slow or unreliable fibre. It doesn’t. The affordable end of the market is still real fibre on the same networks the pricey plans use — you pay less mostly because you picked a lower speed, a value-focused network like Vuma Reach, or simply a cheaper ISP on the identical line. A R500 affordable fibre deal and a R900 one can run over the exact same cable to your house. So the honest way to find affordable fibre internet isn’t to chase the flashiest brand — it’s to see what reaches you and sort by price.
The verdict
Cheap fibre in South Africa is real and getting cheaper — from R199 prepaid lines to sub-R800 gigabit. But "cheapest" only helps if it’s live at your address and the ISP behind it is decent. So do the two-step: check what reaches you, then compare every option on that line by price and rating. For more on where the money goes, see how much fibre costs in South Africa.
