FNO vs ISP in South Africa: Who Owns the Fibre Line and Who Bills You?
Many South African fibre problems become easier once you separate the fibre network operator from the internet service provider.
Quick Answer
The FNO owns or manages the physical fibre infrastructure. The ISP sells the internet package, bills you and is usually your first support contact.
ISP
Package, billing, router, account support and escalation.
Reseller
May sell or bill a package while relying on another provider underneath.
FNO vs ISP responsibilities
| Item | Use | Note |
|---|---|---|
| FNO | Builds and manages the physical fibre network | Examples: Openserve, Vumatel, MetroFibre, Frogfoot, Octotel, Zoom Fibre. |
| ISP | Sells the internet service over the fibre network | Examples: Afrihost, Webafrica, Mweb, Vox, Axxess, RSAWEB, Cool Ideas. |
| Customer support | Usually starts with your ISP | The ISP escalates infrastructure faults to the FNO when the line/network is involved. |
| Coverage | Comes from the FNO, then package availability from the ISP | A provider can serve your suburb but not your exact complex, street or building. |
Questions to ask before ordering
- Which fibre network operator covers my exact address?
- Which ISPs can sell service on that network?
- Who owns the router and ONT?
- Who do I contact if installation is delayed?
- Who do I contact if the line is down but my account is paid?
- What happens if I switch ISP but stay on the same FNO?
Do not guess during a fault
If your fibre is down, start with the ISP that bills you. If the issue is the physical line, the ISP can log or escalate the fault with the network operator.

Frequently Asked Questions
Can DataCost tell me if fibre is available at my exact address?
No. Fibre coverage is address-specific, so DataCost explains what to check and links the decision together, but you must confirm availability on an official provider or FNO coverage checker.
Are the prices on DataCost guaranteed?
No. DataCost treats prices as checked public examples. Final pricing can change by address, FNO, promotion, installation status and provider terms.
Who should I contact when fibre is down?
Start with the ISP that bills you. The ISP can then escalate line or infrastructure faults to the FNO when needed.
DataCost does not sell fibre packages. Use these pages to understand the market, then confirm final price, address coverage, installation terms, router rules and cancellation costs with the official provider.
