Why South Africans pick Supersonic
MTN's wholesale buying power lets Supersonic price aggressively at the entry tiers, and the dual fibre + 5G product means you can move on to a connection while you wait for trenching.
MTN-backed
Owned and operated by MTN — South Africa's largest mobile network and one of the country's biggest fibre buyers.
5G + fibre under one roof
If your address isn't lit yet, Supersonic can put you on MTN 5G fixed-wireless with the same self-service portal.
Aggressive promo pricing
Frequent month-free deals and discounted Wi-Fi mesh add-ons — sharpest at the entry tiers.
Free standard install
Free installation on lit-up addresses across Vumatel, Openserve, Frogfoot and Octotel.
Month-to-month default
No 24-month contracts — most plans are fully month-to-month with 30 days' notice.
Self-service portal
Slick web/app UI for upgrades, payments and support tickets — modern compared to legacy SA ISPs.
Where Supersonic is available
Supersonic resells Vumatel, Openserve, Frogfoot, Octotel, MetroFibre, Vuma Reach, Link Layer and a steady stream of smaller open-access FNOs. The footprint is effectively all of SA's major metros plus a growing list of secondary towns.
Where there's no lit fibre yet, Supersonic falls back to MTN 5G fixed-wireless — a strong stop-gap with sub-50ms ping in 5G-covered areas. Use the Supersonic coverage tool with your exact address to see which products you qualify for.
