Vox on Openserve: the cheapest seller changes by tier

Most pages like this one have a tier to recommend the subject on. This one does not, and that is worth stating plainly rather than burying. Across the nine speed tiers Vox shares with at least one other Openserve seller, it has the cheapest advertised price on 0 and the cheapest twelve-month cost of ownership on 0. Those two zeroes are computed from the catalogue, not asserted: the day Vox cuts a price, this paragraph says something else.

Where it lands instead is between 2nd and 5th on the costed year, and the premium over the cheapest seller on the identical line runs from R96 to R11 201 over twelve months. Taking Vox at every rung of the ladder rather than the cheapest seller at each would cost R14 293 more across the nine tiers in a year.

Note also that Vox’s own position moves between the two columns on five of the nine tiers — 30/30 Mbps, 100/50 Mbps, 100/100 Mbps, 200/100 Mbps and 300/150 Mbps — which is the clearest sign that the advertised monthly price is not a proxy for what the line costs.

This is the finding worth taking away from the page, and it is not about Vox at all. four different sellers hold the cheapest twelve-month position somewhere on the Openserve ladder — Afrihost, MWeb, RSAweb and Webafrica — so any page, including ours, that answers “who is cheapest on Openserve” with one company name is wrong at most speeds. On the advertised price the field looks much narrower, just MWeb and RSAweb, which is precisely how a single-name answer gets written.

More sharply: on six of the nine contested tiers the company with the cheapest advert is not the company with the cheapest year — 30/30 Mbps, 50/25 Mbps, 200/100 Mbps, 200/200 Mbps, 300/150 Mbps and 1000/500 Mbps. A reader who sorts by monthly price and buys the top row is buying the wrong line on those rungs, whoever they end up with.

What that means for how you shop this network

Openserve is a wholesale network: the line into the house is the same piece of glass whoever bills you for it, and the five sellers here — Afrihost, MWeb, RSAweb, Vox and Webafrica — are reselling identical capacity. So nothing on this page is a judgement about network quality, which they all share. The only things that differ are the price, the promotional structure behind it, the once-off, and the contract terms. That is why the twelve-month column exists and why it is the one to read.

Vox’s 1000/500 Mbps line is the one rung to look at hardest, for two reasons that compound. First, it is the only one of Vox’s nine Openserve lines with no promotional rate at all, so the advertised R2 499 is also the standing rate. Second, it is the widest same-line gap on the network: R30 038 over twelve months all in against Webafrica’s R18 837 for the identical line — a difference of R11 201.

The advertised monthly difference is R950/mo, which looks like a decision you could make either way. Over a year it is R11 201, so the monthly figure understates the commitment by 11.8×. This is the single clearest argument on the site for publishing a cost-of-ownership column at all, and the crossover is immediate rather than eventual: Vox is ahead on total spend from month 1.

Every disagreement above has the same two causes, and both are structural rather than anybody’s fault. Vox runs a promotional rate on 8 of its 9 Openserve lines, on windows of two months and three months, and at its steepest the line then steps up by 13.1% of what you were paying. The clock runs from the day the service goes active, not from the day you order, which is worth knowing if an installation slips.

Against that, Afrihost run no promotion on any Openserve line, so their advertised price is their standing rate. Comparing a promotional rate with a standing rate on a monthly basis is comparing two different things, and it is the whole reason the advertised ranking and the costed ranking disagree.

The once-off, which never appears in a monthly price

Every row in this pool publishes a once-off charge, which is unusual enough to be worth saying: it is what lets this page print an all-in ranking rather than a recurring-only one. Vox charges R50–R230 by line — an order-processing fee covering admin and router delivery by its own description. Afrihost states a once-off of zero, which is a published R0 rather than a missing value — the distinction matters, because an unstated fee is not the same as no fee and this page never treats one as the other.

two speed tiers on Openserve are sold by another seller and not by Vox. Showing the gap is more useful than quietly dropping it, because if one of these is the line you want then this page has told you to go elsewhere.

One of those gaps is our reporting decision rather than a hole in Vox’s range, and it should be stated rather than left to look like the other. Vox does sell a 500/250 line on Openserve, but its own product feed prices it to a fraction of a cent — the only non-integer rand figure in the payload — and this catalogue will not round a price into existence. So we do not publish that row, and the tier shows as absent above. The promotional leg of the same line is a clean integer; the row becomes publishable the day the standing price is one too.

A fibre line is rarely a twelve-month decision, so the same contest run over 24 months is the fairer test for anyone not planning to move. Over two years Vox leads the advertised price on 0 of nine contested tiers and the recurring cost on 0, and the advertised and costed rankings disagree on four — fewer than the five at twelve months, because a promotional window is a smaller share of a longer horizon and its effect dilutes.

The gap between an advertised monthly price and that last column is the number worth carrying away. On 30/30 Mbps it is R450 advertised against R514 averaged over two years.

None of the above is a judgement about Openserve, which every seller on this page shares. It is the largest fibre network in the country by homes passed: 1 565 750 homes passed and 843 563 connected as at Jun 2026, an uptake rate of 53.9%. Source: Telkom Q1 FY2027 trading update, 3 Aug 2026. In the February 2026 ISPA survey of South African networks it scored 6.5 out of ten from 38 rating ISPs — the largest rater base in that survey, against a 45-network average of 6.2.

Wholesale prices move, and when they do every seller on this page moves with them. Our records hold eight per-tier Openserve price changes in 2026, averaging +3.17%. That is the context for reading any promotional rate on this page as temporary in two senses at once.
