Openserve — fibre network operator in South Africa
Openserve is the Telkom Group’s wholesale division and South Africa’s largest internet infrastructure provider, running the biggest fixed broadband network in the country. It states plainly on its own site that it is not an internet service provider: you check coverage with Openserve, then sign up with an ISP that sells over the network. Openserve connects South Africa to each neighbouring country by dual terrestrial fibre and operates a fully redundant submarine fibre ring around the African continent.
Key facts
| Who they are | The Telkom Group’s wholesale division and South Africa’s national connectivity leader, described on its own site as the largest internet infrastructure provider with the biggest fixed broadband network in the country |
| Internet services | Fibre to the home, business connectivity and estate or complex broadband, all sold through internet service providers rather than direct. Prepaid fibre bundles are also available through ISP partners |
| Also offers | WebReach, a wholesale IP transit service giving more than two thirds of South Africa’s internet service providers their Tier 1 internet access, with peering at LINX, AMS-IX, DE-CIX and NAP Africa |
| Head office | Not published on the site. Openserve is a division of the Telkom Group rather than a separately addressed company |
| Coverage | National, with dual terrestrial fibre routes into each neighbouring country and a fully redundant submarine fibre ring around the African continent. Availability at your address is confirmed through the Openserve coverage checker |
| ICASA licence | No ICASA reference is published on the site. As the Telkom Group’s wholesale division, the relevant licences sit at group level. Ask for the reference in writing if procurement records it |
| Pricing | Not set by Openserve. Featured ISP partner deals are displayed — R389 a month for 20/10Mbps uncapped, R459 for 40/20 and R539 for 30/30 at the time of sampling — but those are the ISPs’ retail prices, not Openserve’s |
| Prepaid change | From 1 June 2026 only 30-day prepaid recharge vouchers are available. The 3, 7 and 14-day vouchers have been discontinued, which matters if you were relying on short-term top-ups |
| Google profile | No corporate Google Business Profile exists. Searches return individual Telkom exchange buildings carrying the openserve.co.za domain — one Durban exchange rates 1.8 from 18 reviews. A single exchange is not a rating for a national wholesale network, so none is shown |

They say it themselves: Openserve is not an ISP
Most confusion about Openserve dissolves once you read the notice on its own contact page, which tells customers that Openserve is not an internet service provider and that faults must go to your ISP. That is the whole model. Openserve builds and maintains the fibre; the ISP you sign with sells the package, bills you and answers the phone. So a slow line is usually a network question and a billing dispute is almost always an ISP question, even though both get blamed on the same name. The practical consequence when you shop is that the identical Openserve line carries very different prices depending on which provider you buy from, so compare at least two on the same speed before committing. The WebReach side is worth knowing about too: most South African ISPs buy their upstream internet access from Openserve, which is why its network shows up behind competitors who never mention it. Compare retail options in the fibre provider directory.
Who Openserve is a fit for
- Homes and businesses inside the country’s largest fibre footprint
- Buyers who want to choose their ISP rather than be tied to one
- Estates and complexes needing a national network operator

Because Openserve sells infrastructure rather than internet packages, the useful next step is comparing the ISPs that ride the network. Have your street address ready for a coverage check, the speed you need in both directions, and whether the line serves a home, a business or a whole estate.

Can I buy internet directly from Openserve?
No, and Openserve says so on its own site: it is not an internet service provider. You check coverage with Openserve, then sign up with an ISP that sells over the network. That ISP bills you and handles faults.
Who is Openserve owned by?
Openserve is the Telkom Group’s wholesale division, described on its own about page as the group’s redesigned wholesale arm and South Africa’s largest internet infrastructure provider.
Why do different ISPs charge different prices for the same line?
Because Openserve sets the wholesale cost and each ISP sets its own retail price on top. The identical Openserve line can therefore cost noticeably different amounts depending on who you sign with. Compare at least two providers on the same speed.
What is WebReach?
It is Openserve’s wholesale IP transit service, which the company states provides Tier 1 internet access to more than two thirds of South Africa’s ISPs, with peering at LINX, AMS-IX, DE-CIX and NAP Africa. It is sold to operators, not to end users.
Has anything changed with prepaid fibre?
Yes. From 1 June 2026 only 30-day prepaid recharge vouchers are available; the 3, 7 and 14-day vouchers have been discontinued. Check this if you were relying on short-term top-ups.
Why is no customer rating shown?
Openserve has no corporate Google Business Profile. Searches return individual Telkom exchange buildings that carry the openserve.co.za domain, one of which rates 1.8 from 18 reviews. Attaching a single exchange’s rating to a national wholesale network would mislead, so WhichVoIP shows none.
