Plain-English buyer's guide to wireless internet for SA businesses. When fibre isn't an option (or while you wait), what to actually buy — and what to avoid.
Wireless internet covers any fixed business connection that doesn't run over a physical cable to your building — including LTE/5G mobile broadband, fixed wireless access (FWA), and licensed point-to-point microwave links. In South Africa, wireless is the right answer when fibre can't reach your address, when you need a fast install, or when you need a backup line for your fibre connection. Pricing ranges from R299/month for an entry LTE plan to R8,000+/month for a dedicated business microwave link.
This guide explains the four wireless technologies, what each is good for, what to budget, and how to choose between them. We also cover the failure modes (weather, contention, line-of-sight) that wireless suffers and fibre doesn't.
For most South African businesses, 5G fixed wireless from Rain, Vodacom, or MTN at R599 to R1,299 per month is the best wireless internet when fibre is unavailable. For mission-critical sites needing a fibre-grade SLA, licensed microwave point-to-point from a regional WISP is the right choice at R3,000 to R8,000+ per month. Always check fibre availability first.
This guide assesses wireless internet for South African business buyers and draws on three primary data sources. First, the ICASA register: every provider is cross-checked against the regulator's licence database so the list reflects current ECS/ECNS holders and excludes unlicensed resellers. Second, the WhichVoIP provider directory of 611 listings, maintained as a primary-source database with monthly verification cycles. Third, WhichVoIP's review research: 58 published V7 reviews with verbatim customer-review extracts and a four-axis score methodology.
The pillar covers four technologies: LTE, 5G fixed wireless, fixed wireless access (FWA) from regional WISPs, and licensed point-to-point microwave. It excludes residential-only plans, satellite (covered separately), and providers without active ICASA registration.
Ranking criteria: published rate per Mbps, service-level commitment, coverage breadth across South African metros and peri-urban areas, and verified customer feedback from primary sources. We do not accept paid placement on this page. Our recommended-provider table is an independent assessment.
Refresh cadence: this page is refreshed every 90 days against live provider pages and the current ICASA register. The last refresh date is shown in the page header. What you will not find here: vendor rebate marketing, unverified partner-tier claims, or provider self-rankings.
Wireless internet in SA isn't one technology — it's four very different ones with very different price tags and use cases:
Uses the same cell towers as your phone. Cheapest to set up — just plug in a SIM and a router. Speeds typically 10–80 Mbps depending on tower load and distance. Best for small offices, branches, and as a fibre backup. Vodacom, MTN, Cell C, Rain, Telkom Mobile.
Newer mobile spectrum, much faster — 100–500+ Mbps in coverage areas. Same plug-and-play simplicity as LTE. Coverage is still patchy outside metros. Rain, Vodacom, MTN, Telkom.
Dedicated radio link from a WISP (wireless ISP) tower to a small dish on your roof. Better contention than LTE, more predictable speeds, business SLAs available. Speeds 25–200+ Mbps. Herotel, MetroFibre Wireless, regional WISPs.
Dedicated, contended-1:1, business-grade radio link. Symmetric speeds, hard SLA, no contention with anyone else. Expensive. Used for offices that need fibre-grade reliability where fibre doesn't reach. R3,000–R8,000+/month.
Fibre wins on almost every metric. Wireless wins on coverage, install speed, and portability:
| Factor | Fibre | Wireless |
|---|---|---|
| Speed consistency | Excellent | Variable (peak hours, weather) |
| Install time | 7–21 days | 1–3 days |
| Coverage | Metros and suburbs | Almost everywhere |
| Latency | 5–20ms | 20–80ms |
| Affected by weather | No | Yes (rain, wind) |
| Per-Mbps cost | Cheap | 2–5x more |
| Portability | None | Full (LTE/5G) |
If fibre is available at your address, buy fibre. Wireless is the right answer for buildings fibre can't reach, branches that need to come online fast, and as a redundant backup link for businesses that can't afford downtime.
Pricing varies enormously by technology:
| Type | Capped (50 GB) | Uncapped | Best for |
|---|---|---|---|
| LTE business | R299–R499 | R599–R899 | Backup, branches, small offices |
| 5G fixed | R599–R799 | R899–R1,299 | Metro offices without fibre |
| FWA (WISP) | — | R899–R2,500 | Suburban / peri-urban offices |
| Microwave P2P | — | R3,000–R8,000+ | Mission-critical, fibre-grade SLA |
Most "uncapped" LTE and 5G plans throttle to 2–10 Mbps after a fair-use threshold (usually 100–500 GB/month). For a small office that's plenty. For VoIP-heavy or video-streaming use, check the throttle speed before signing.
Wireless has failure modes fibre simply doesn't have. Knowing them lets you plan around them:
None of these are deal-breakers — they're trade-offs. Plan for them, set realistic expectations, and don't try to run a 50-agent call centre on a single LTE SIM.
Five rules to pick the right wireless option without overspending:
Side-by-side specs and SA pricing across LTE, 5G and fixed wireless.
These are the sixteen providers that fit most businesses and sell a real fixed-wireless, LTE or 5G product, ordered by review score rather than by what anyone pays us. Each name links to an independent WhichVoIP review. Fibre-only ISPs and network operators are deliberately not listed here, even where they are strong in their own category.

| Afrihost | Multi-FNO fibre plus LTE and 5G mobile broadband, month-to-month | Small offices wanting a no-contract wireless line |
| Cool Ideas | Fixed-wireless 5G option alongside multi-FNO fibre | Teams wanting a 5G fallback from a top-ranked ISP |
| Axxess | 5G and LTE across all three SA mobile carriers | Sites needing carrier choice on a single account |

These six are reviewed against the same four-axis rubric but sit outside the shortlist for most buyers. They remain worth a look if one of them already serves your business or you need a single national supplier: Herotel, MTN Business, Vodacom Business, Telkom, Supersonic and Cell C.
