123NET — fibre network operator & ISP in South Africa
123NET is a Durban-based fibre network operator and internet service provider founded in 2014, running its own fibre backbone from its head office in Umhlanga and selling the internet service on top of it. Home fibre starts at R399 a month for a symmetric 20Mbps line on a 12-month term and scales to 1000Mbps, all uncapped and unshaped with a three-lane split across local, national and international traffic. Because 123NET is both the network and the ISP, a single company handles the line and the support.

A fibre network operator that is also your ISP
Most home fibre in South Africa splits the line and the service between two companies, a fibre network operator that trenches the cable and a separate ISP that bills you. 123NET does both on its own backbone, so one company answers for coverage, speed and support. Whether it can serve you comes down to whether that backbone has reached your street, which a coverage check against your address confirms. The three-lane split matters because local traffic to South African sites stays fast even when international routes are congested.
Who 123NET is a fit for
- KwaZulu-Natal homes and businesses that want one company for both the fibre line and the internet service.
- Households that value uncapped, unshaped fibre with a clear local, national and international split.
- Buyers who want month-to-month flexibility on the GO range rather than a locked contract.

Is 123NET a fibre network operator or an ISP?
Both. 123NET owns and runs its own fibre backbone and also sells the internet service on top of it, so a single company handles the line, the connection and the support rather than splitting those between a network operator and a separate ISP.
How much does 123NET fibre cost?
Home fibre starts from R399 a month including VAT for a symmetric 20Mbps line on a 12-month term, and scales up to 1000Mbps. The price depends on the speed you choose, and a quote confirms the figure for your address.
Is my address covered by 123NET?
Coverage follows 123NET’s own fibre footprint, which is concentrated in KwaZulu-Natal around Durban. A coverage check against your street address is the quickest way to confirm whether the network has reached you and which speeds are available.
Is 123NET fibre uncapped and unshaped?
Yes. 123NET markets its home fibre as uncapped and unshaped, with a three-lane split that separates local, national and international traffic so South African browsing stays fast even when international routes are busy.
Does 123NET offer business connectivity and voice?
Yes. Alongside home fibre, 123NET lists business connectivity and voice products on the same network, priced on quote. A quote can scope a business line, and any voice, against the fibre connection.
Can I go month-to-month with 123NET?
The GO plans can run month-to-month or on a 12-month term, so you can choose flexibility or a longer commitment. Entry pricing such as the R399 tier is quoted on the 12-month term; a quote confirms the month-to-month figure.
