The speed-tier value cliff
Fibre gets cheaper per megabit the faster it goes, and the drop is steep enough to invert the sticker price. Compare what a typical 20 Mbps line costs against the cheapest line one tier up.
| Tier | Packages | Median price | Median R/Mbps | Cheapest one tier up | Difference | Beaten by it |
|---|---|---|---|---|---|---|
| 10 Mbps | 20 | R447 | R39.90 | 20 Mbps at R249 — RSAweb on Metro Nexus | −R198 | 20 of 20100% |
| 20 Mbps | 84 | R525 | R19.90 | 40 Mbps at R299 — RSAweb on Octotel | −R226 | 83 of 8499% |
| 40 Mbps | 140 | R697 | R13.43 | 100 Mbps at R99 — RSAweb on Octotel | −R598 | 140 of 140100% |
| 100 Mbps | 150 | R879 | R8.69 | 200 Mbps at R299 — RSAweb on Octotel | −R580 | 149 of 15099% |

20 Mbps fibre, by network and over two years over two years
There are 84 20 Mbps packages in the table above, spread across 33 fibre networks. They are not interchangeable: the cheapest way onto Metro Nexus is R249 a month, while the same question on WeFNO starts at R697. Which networks reach your address is usually decided for you, so the useful comparison is within a network rather than across the whole list.
| Network | 20 Mbps packages | Cheapest | Speed | Best R/Mbps, any plan |
|---|---|---|---|---|
| Metro Nexus | 5 | R249/mo | 30/30 Mbps | R8.30 |
| Evotel | 5 | R355/mo | 30/30 Mbps | R11.83 |
| Openserve Web Connect | 3 | R365/mo | 20/10 Mbps | R18.25 |
| Fibre Geeks | 6 | R379/mo | 20/10 Mbps | R18.95 |
| Accelerit | 2 | R393/mo | 25/25 Mbps | R15.72 |
| Evotel Pulse | 1 | R395/mo | 20/20 Mbps | R19.75 |
| Vumatel | 5 | R399/mo | 30/30 Mbps | R13.30 |
| Octotel | 2 | R399/mo | 20/10 Mbps | R19.95 |
| Herotel | 1 | R399/mo | 20/10 Mbps | R19.95 |
| Vuma Reach | 3 | R417/mo | 20/10 Mbps | R20.85 |
| Frogfoot Air | 4 | R435/mo | 25/10 Mbps | R17.40 |
| Openserve | 5 | R437/mo | 30/30 Mbps | R14.57 |
| 21 smaller networks | 42 | from R439/mo | various | see table above |
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 R249 for 30 Mbps on Metro Nexus, which is R8.30 per Mbps; the best unit price in the whole segment is R8.30 per Mbps. Paying a little more for a much faster line is usually the better deal; paying the minimum almost never is.
| Monthly | 12 months | 24 months | |
|---|---|---|---|
| Promotional rate, if it never ended | R249/mo | R2 988 | R5 976 |
| Standing rate after promo | R495/mo | R5 940 | R11 880 |
| Once-off fee | R250 once | R250 | R250 |
| What you actually pay | R454/mo avg | R5 452 | R11 392 |
The first row is the number that gets advertised, and it is the one to ignore. Metro Nexus is discounted from R495 to R249 for the first 3 months, then steps up by R246 a month — a 99% increase on the rate that sold you the line. Over two years that is R11 392 rather than the R5 976 the headline price implies, which works out at R475 a month rather than R249. Budget on the standing rate and treat the discount as a rebate on the first few months. The totals above include the R250 once-off charge this line carries, but not a router you buy outright. 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.

What 20 Mbps actually gives you
Real-world expectations for a 20 Mbps fibre line, based on average device count, codec efficiency and SA peering as of 2026.
| Activity | Verdict | What to expect |
|---|---|---|
| 4K streaming (1 device) | Great | Netflix 4K uses ~25 Mbps but adapts. 20 Mbps gives high-quality 4K on most content. |
| HD streaming (2 devices) | Great | Two HD streams fit easily, lounge TV + bedroom tablet. |
| Video calls (1 person) | Great | Zoom, Teams and Google Meet all run smooth in HD. |
| Online gaming (1 player) | Great | Console and PC gaming feel identical to 100 Mbps. Latency is what counts. |
| Game patch downloads | ~ OK | 100 GB patch ≈ 11 hours. Fine if you start it overnight. |
| Working from home (1 person) | Great | Cloud apps, Slack, video calls, comfortable for a single remote worker. |
| Two simultaneous Zoom calls | ~ OK | Will work but uploads may stutter if anyone else is sending files. |
| 5 GB HD movie download | Great | Approximately 36 minutes. |

The case for 20 Mbps
True 4K streaming
First tier where Netflix, Disney+ and Showmax 4K streams hold steady without buffering.

Comfortable for 2 people
A couple working/streaming from home rarely hits the cap on this tier.
Strong price-per-Mbps
20 Mbps is usually the value sweet spot - double the speed of 10 Mbps for a fraction more. Compare the per-Mbps figure on every row above.
Handles smart home devices
Cameras, doorbells, smart TVs and IoT all sit happily in the background on 20 Mbps.
Future-proof for a year or two
Even with one extra household member, 20 Mbps holds up, until you add gaming or a second WFH adult.
