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 100 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 R299 — RSAweb on Metro Nexus | −R148 | 19 of 2095% |
| 20 Mbps | 88 | R517 | R19.63 | 40 Mbps at R299 — RSAweb on Octotel | −R218 | 87 of 8899% |
| 40 Mbps | 140 | R697 | R13.32 | 100 Mbps at R379 — RSAweb on Octotel | −R318 | 139 of 14099% |
| 100 Mbps | 151 | R879 | R8.75 | 200 Mbps at R379 — RSAweb on Octotel | −R500 | 150 of 15199% |
| 200 Mbps | 119 | R1 109 | R5.02 | 500 Mbps at R699 — RSAweb on Vumatel | −R410 | 115 of 11997% |

100 Mbps fibre, by network and over two years over two years
There are 151 100 Mbps packages in the table above, spread across 39 fibre networks. They are not interchangeable: the cheapest way onto Octotel is R379 a month, while the same question on Thinkspeed starts at R1 037. 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 | 100 Mbps packages | Cheapest | Speed | Best R/Mbps, any plan |
|---|---|---|---|---|
| Octotel | 6 | R379/mo | 100/100 Mbps | R3.79 |
| Vumatel | 10 | R449/mo | 100/100 Mbps | R4.49 |
| Herotel | 1 | R499/mo | 120/120 Mbps | R4.16 |
| Frogfoot | 10 | R599/mo | 120/60 Mbps | R4.99 |
| Metro Nova | 8 | R599/mo | 80/80 Mbps | R5.66 |
| Accelerit | 3 | R653/mo | 70/70 Mbps | R7.53 |
| Fibre Geeks | 11 | R689/mo | 75/25 Mbps | R7.69 |
| Openserve | 11 | R697/mo | 75/75 Mbps | R7.77 |
| Metro Nexus | 9 | R699/mo | 100/100 Mbps | R5.53 |
| Clearwire | 4 | R747/mo | 75/50 Mbps | R6.58 |
| Balwin Fibre | 4 | R780/mo | 120/120 Mbps | R6.50 |
| Evotel | 5 | R789/mo | 120/120 Mbps | R6.58 |
| 27 smaller networks | 69 | from R789/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 R379 for 100 Mbps on Octotel, which is R3.79 per Mbps; the best unit price in the whole segment is R3.79 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 | R379/mo | R4 548 | R9 096 |
| Standing rate after promo | R845/mo | R10 140 | R20 280 |
| Once-off fee | R250 once | R250 | R250 |
| What you actually pay | R788/mo avg | R9 458 | R19 598 |
The first row is the number that gets advertised, and it is the one to ignore. Octotel is discounted from R845 to R379 for the first 2 months, then steps up by R466 a month — a 123% increase on the rate that sold you the line. Over two years that is R19 598 rather than the R9 096 the headline price implies, which works out at R817 a month rather than R379. 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.

Who 100 Mbps is built for
Best for Business, best for power users / sme. Here's where it shines and where it falls short.
Best for
- Large families & shared houses5+ people, all streaming/gaming/working at the same time without anyone slowing anyone else down.
- Small businesses & home officesFile servers, cloud backups, multi-line VoIP, video conferencing, handles a small office stack comfortably.
- Power users & creatorsTwitch streamers, YouTube creators, photographers, video editors uploading large files daily.
- Anyone who hates waiting100 GB game downloads in ~2 hours. Cloud backups in minutes. Big email attachments instant.
Not for you if
- You're a single light user, you'll never use it
- Your address only has asymmetric Openserve (uploads will bottleneck)
- You're on a budget and you're not running a business, 40 Mbps is enough
The case for 100 Mbps
Symmetric on most networks
100/100 Mbps from Vumatel, Frogfoot and Octotel means uploads keep pace with downloads, critical for cloud and creator workflows.
Future-proof for years
Even as 4K becomes 8K and device counts climb, 100 Mbps holds up for the next 5+ years of household growth.
Genuine SME-grade
Many small businesses run their entire office on a 100 Mbps residential fibre line, VoIP, file servers, video calls, backups.
Downloads you can wait out
A 5 GB HD movie takes about 7 minutes and a 50 GB game a little over an hour - at 100 Mbps you start a big download and come back to it, rather than planning your evening around it.
Best price-per-Mbps
100 Mbps is typically only ~50% more expensive than 40 Mbps for 2.5× the speed, the tier with the best value if you can use it.
No contention, ever
On 100 Mbps, multiple users hammering the line simultaneously is the only realistic way to feel a slowdown.
