MWeb on Openserve 2026

Every price above is a monthly figure, and most of them are promotional. MWeb discounts its Openserve range for the first two months and then bills the standing rate, so the number on the advert is not the number you live with. The figure below ranks the same pool twice over — as advertised, and as it actually bills — so the rows that move are visible at a glance.

Over 24 months the two promotional months barely register and the standing rate is almost the whole bill, which reorders the table again. This is the view that counts if you are not planning to move.

Openserve is a wholesale network, so MWeb is not selling a different line from its rivals — it is selling the same physical fibre with a different bill attached. That makes this an unusually clean comparison: identical FNO, identical speed pair, and the only variable is the ISP.

Of the 15 speed pairs sold on Openserve, MWeb competes on 13. It has the cheapest advertised price on 1 of those, and the cheapest twelve-month cost on 1. 9 of the 13 contested tiers change their ranking once a full year is costed, which is the single most useful thing on this page.

The sharpest case is 500/250 Mbps. MWeb advertises R1 399/month against Webafrica’s R1 339/month — a gap of R60 on the advert. Costed over twelve months it is R18 138 against R16 068, so the identical line costs R2 070 more through MWeb over the first year. The advertised gap understates the first-year gap by 34.5×, which is the whole argument for printing a cost-of-ownership column at all.

Two gaps worth naming, because a comparison that only lists what MWeb sells is not a comparison. MWeb does not sell 25/25 Mbps or 75/75 Mbps on Openserve at all: RSAweb sells 25/25 Mbps at R515; RSAweb sells 75/75 Mbps at R697.

Right for you if…

• You want 200/100 Mbps — MWeb is the cheapest seller on this tier over a full year, not just on the advert. That is the unambiguous case.
• You are moving within two months — if you will not be on the line long enough to meet the step-up, the advertised price is the price you pay, and MWeb leads the advert on 1 of 13 contested tiers.
• Coverage is the binding constraint — Openserve reaches more South African addresses than any other fibre network, so for a great many homes this is not a choice between networks but the only fibre on the street.
• Value per megabit is what you are buying — 1000/500 Mbps at R1 599 works out to R1.60/Mbps, against R31.90/Mbps on 10/5 Mbps.
• You want the router and the terms included — a free-to-use managed router and month-to-month billing with 30 days’ notice, with no early-termination fee on most packages.

Look elsewhere if…

• You want 30/30 Mbps — RSAweb costs R5 924 over twelve months against MWeb’s R6 168, a difference of R244 for the identical physical line.
• You want 50/25 Mbps — Afrihost costs R8 364 over twelve months against MWeb’s R8 538, a difference of R174 for the identical physical line.
• You want 50/50 Mbps — RSAweb costs R9 344 over twelve months against MWeb’s R9 858, a difference of R514 for the identical physical line.
• You want 100/50 Mbps — RSAweb costs R10 504 over twelve months against MWeb’s R10 818, a difference of R314 for the identical physical line.
• You want 100/100 Mbps — Webafrica costs R11 508 over twelve months against MWeb’s R11 898, a difference of R390 for the identical physical line.
• You want 200/200 Mbps — Webafrica costs R13 668 over twelve months against MWeb’s R14 298, a difference of R630 for the identical physical line.
• You want 300/150 Mbps — Webafrica costs R14 508 over twelve months against MWeb’s R15 258, a difference of R750 for the identical physical line.
• You want 500/250 Mbps — Webafrica costs R16 068 over twelve months against MWeb’s R18 138, a difference of R2 070 for the identical physical line.
• You want 25/25 Mbps or 75/75 Mbps — MWeb does not sell these tiers on Openserve at all, so no promotion closes this gap.
• Your address does not show Openserve — then none of the prices above can help you, and comparing them is wasted effort. Coverage is decided by which network reached your street, not by which ISP you prefer. Start at the fibre coverage map instead.
• You are buying the entry tier purely on monthly price — 10/5 Mbps is the worst rand-per-megabit on MWeb’s own Openserve ladder at R31.90/Mbps. That is this site’s own differentiator metric arguing against its own cheapest row, and it is usually the right advice: one rung up buys far more line per rand.

If a cheaper seller on the same line is what you are after, the Openserve deals page ranks every ISP on the network, and compare fibre deals puts every network beside it.
