Atomic — fibre internet provider in South Africa
Atomic is a fibre-only internet service provider working the Western Cape, founded in 2017 and trading from Gordon Street in Cape Town’s Gardens. It sells uncapped home and business fibre across the City of Cape Town and the Cape Winelands district, riding the four major open-access networks in the province rather than building its own trench. The company received its AS number in January 2018 and launched to customers that August. It listed as Atomic Access before moving to the atomic.co.za domain.

Whether Atomic reaches your address
Fibre coverage is a question about your street, not the province. Atomic sells on Octotel, Frogfoot, Vumatel and Openserve, so the practical test is which of those four has trenched past your building — that decides both the speed tiers you can buy and what you pay, because each network carries its own price table. The footprint stops at the City of Cape Town municipality and the Cape Winelands, so an address in Gauteng or KwaZulu-Natal is outside their book entirely. Buyers weighing a wider set of options can start at the fibre provider directory.
Who Atomic is a fit for
- Cape Town and Winelands households that want a small, local ISP rather than a national brand
- Buyers who want a choice of four open-access networks quoted by one provider
- Anyone in the Cape Town CBD chasing multi-gig speeds now that XGS-PON is live

Who is Atomic and where do they operate?
Atomic is a Cape Town fibre internet service provider founded in 2017 and based at 2 Gordon Street in Gardens. It sells across the City of Cape Town municipality and the Cape Winelands district, and it does not currently trade outside the Western Cape.
Is Atomic the same company as Atomic Access?
Yes. The business traded publicly as Atomic Access and now uses the shorter Atomic name on the atomic.co.za domain. The older atomicaccess.co.za address redirects to the current site.
Which fibre networks does Atomic use?
Four open-access fibre network operators: Octotel, Frogfoot, Vumatel and Openserve. Atomic does not own trenched fibre itself, so which network passes your address decides the packages and prices you can be quoted.
What does Atomic fibre cost?
Published entry pricing starts at R699 per month for 25/25 Mbps on Octotel. A 100/100 Mbps line runs R989 per month, and the 2500/2500 Mbps XGS-PON package is R2,349 per month. Frogfoot, Vumatel and Openserve each have their own price table. For reference, the 13 verified Fibre providers on WhichVoIP that do publish prices charge R279–R795 per month for an entry package, rising with speed and a business SLA — a yardstick for the figures above.

Can I get multi-gigabit fibre from Atomic?
In parts of the Cape Town CBD and surrounding areas, yes. Atomic launched XGS-PON packages in December 2025 running to 2500/2500 Mbps symmetrical. Availability is tied to the XGS-PON build, so it is narrower than their standard footprint.
Does Atomic sell business fibre as well as home fibre?
Yes, the company sells both residential and business fibre on the same four networks. Business buyers should confirm the service-level terms and any uptime commitment in writing, because those are what separate a business product from a home line.
