Uncapped Fibre from R279

There are 679 uncapped plans in the table above, spread across 45 fibre networks. They are not interchangeable: the cheapest way onto FibreSuburb Networks is R279 a month, while the same question on Cybersmart starts at R799. Which networks reach your address is usually decided for you, so the useful comparison is within a network rather than across the whole list.

The last column is the best rand-per-Mbps available anywhere on that network, at any speed — not the unit price of the cheapest line beside it. The two are rarely close, and the gap is the argument against buying on headline price. The entry tier in this segment is R279 for 5 Mbps on FibreSuburb Networks, which is R55.80 per Mbps; the best unit price in the whole segment is R0.80 per Mbps. Paying a little more for a much faster line is usually the better deal; paying the minimum almost never is.

No promotional rate applies to this line, so the advertised price is what you pay from day one — there is no step-up a few months in. Neither total includes installation or a router, because no per-package once-off figure is published for this line — most lines in this segment bundle both, and the deal cards above list what each one includes. Cancellation terms are the other cost that does not appear in a monthly price: no fixed term is not the same as no cancellation fee, and several ISPs here claw back a waived install if you leave inside six or twelve months.

Looking wider than this segment? Compare every fibre deal we track puts the full catalogue in one sortable table, and the cheapest fibre deals ranks the whole market on price and rand-per-Mbps rather than within one network.

Three words get used as if they mean the same thing, and they do not. A package can be uncapped and still be slowed down. Knowing which promise you are actually buying is the difference between a line that behaves the way you expected and a monthly argument with support.

Every line in the table on this page is uncapped, unshaped, unthrottled and billed monthly, because the page filters to exactly that. Prepaid passes are deliberately excluded: a pass buys a window rather than a month, so listing one beside monthly rates would compare two different things and make the pass look like the cheapest deal on the page when it is not.

The honest caveat is contention. None of these words promise you the full line speed at 20:00 on a Sunday. What they promise is that nothing in your contract is deliberately slowing you down. Congestion on the network operator’s side is a separate problem, and it is the one worth asking neighbours about before you sign.

About 26% of the uncapped lines listed above are promotional rates rather than standing ones. The headline price is real, but it is not what you pay indefinitely - and the gap between the promo and the rate it reverts to is frequently larger than the gap between two ISPs you were agonising over.

We do not publish a “total cost over 24 months” for these, and the reason is worth stating plainly: we track the promotional price and the rate it reverts to, but we do not track promo length uniformly across every ISP. Multiplying out a two-year total would mean assuming a duration we have not verified, and a confident wrong number is worse than an admitted gap. Ask the ISP how many months the promo runs before you sign, then do that multiplication yourself with a figure you have confirmed.

The practical rule: compare the reverts-to column, not the promo column, if you intend to stay longer than a year. On a month-to-month contract you can leave when the rate jumps, which is exactly why month-to-month fibre deals are worth preferring where the price is close.

An uncapped line is the right default for most South African households, but it is not the right answer for everyone, and there is no version of this page that earns anything by pretending otherwise.

• You use very little data and the line is idle most of the month. A single person who browses and streams one show an evening is buying insurance against a cap they would never have hit. A cheaper entry-level line at a lower speed is the better trade - start at 10 Mbps or 20 Mbps rather than paying for headroom.
• You do not have a debit order or want no contract at all. Prepaid fibre products exist for exactly this and they are not listed here, because they are not monthly products. That is a real gap in this page, not an argument against them.
• Your household is small and your router is old. Buying a faster uncapped line changes nothing if the bottleneck is the hardware in your lounge. Test on a cable first; replacing the router is usually the cheaper fix.
• You need a service-level agreement or a static IP. Every package on this page is residential. Uncapped is not the same as guaranteed, and none of these carry a repair-time commitment. If your income depends on the line, price a business product instead.
• Fibre has not reached your street. No amount of comparing helps until a network is live at your address. Start with the fibre coverage map, then come back and filter this table to the network that actually reaches you.
