Check fibre first; if it can’t reach you, uncapped LTE, 5G or a fixed-wireless line covers most businesses, and licensed microwave covers the sites that cannot go down. If fibre can reach you, buy fibre. If it can’t, most South African businesses are best served by uncapped LTE or 5G from a national mobile network, or a fixed-wireless line from a regional wireless ISP. Sites that cannot tolerate downtime should look at licensed microwave, which is priced per site on quote.
Three questions narrow it down. Answer them for your site:
Read the fair-use policy before you sign – “uncapped” rarely means full speed without limit. Per-provider prices are on the wireless internet provider comparison.
Business wireless internet is any fixed business connection that reaches your building by radio instead of a cable – LTE and 5G on the mobile networks, fixed wireless access (FWA) from a wireless ISP’s tower to a dish on your roof, and licensed point-to-point microwave. In South Africa it is the right buy when fibre cannot reach your address, when a site has to go live this week, or when you need a second line that keeps working when the fibre goes down.
“Wireless internet” in South Africa is four different products with different price tags, install routes and failure modes. Know which one a quote is for before you compare prices:
Runs on the same cell towers as your phone: a SIM in a router and you are online, often the same day. Speed depends on how busy the tower is and how far away you are. The right fit for small offices, branches and a backup line behind fibre. Sold by the mobile networks (Vodacom, MTN, Telkom, Cell C, Rain) and by ISPs that resell their capacity.
Newer mobile spectrum with far more capacity than LTE and the same plug-in simplicity, but coverage is still concentrated in the metros. Check coverage at your exact address, not the suburb. Rain, Vodacom, MTN and Telkom sell it directly; several ISPs resell it.
A dedicated radio link from a wireless ISP’s (WISP’s) tower to a small dish on your roof. Because the tower serves fewer, fixed customers, speeds are more predictable than on a busy mobile tower, and business SLAs are available. Regional WISPs are strongest here, especially in suburban, peri-urban and farming areas fibre has not reached.
Fixed wireless is the type most buyers have not seen installed. Follow the connection from the tower to your desk:
A dedicated, uncontended radio link between two fixed points on a licensed frequency: symmetric speed, a hard SLA and no neighbours sharing your capacity. It is the wireless answer for sites that need fibre-grade reliability where fibre does not reach, and it is priced per site on quote.
The mobile networks run LTE and 5G on radio spectrum licensed by ICASA, and any provider selling you a connection needs an ICASA electronic communications licence – an ECS licence covers the service; an ECNS licence additionally covers building network. Ask which licence your service runs under.
Go deeper: fibre vs fixed wireless vs 5G for calls Rain 5G vs fibre
Fibre wins on almost every performance measure. Wireless wins on reach, install speed and portability:
| Factor | Fibre | Wireless |
|---|---|---|
| Speed consistency | Steady all day | Varies with tower load and weather |
| Install time | Days to weeks (trenching, wayleaves, building access) | Often the same week; LTE/5G can be same day |
| Coverage | Metros, suburbs and business parks | Wherever there is signal or line of sight |
| Latency | Lowest and most stable | Higher and more variable |
| Affected by weather | No | Yes (heavy rain, wind on dishes) |
| Cost per Mbps | Usually lower | Usually higher |
| Portability | None | Full on LTE/5G |
If fibre is available at your address, buy fibre (our fibre internet guide covers how). Wireless is the right answer for buildings fibre can’t reach, branches that must come online fast, and as a redundant backup for businesses that can’t afford downtime.
The bottom line: check fibre availability at your address before shopping wireless plans. Wireless is the right call when fibre can’t reach you, or as the second line behind it – not the default.
The headline price is the monthly line fee only. What you actually pay is the line, plus any router or installation, plus whatever happens after the fair-use threshold. The honest way to read the market is by the shape of the product, not by one “average” number:
| Product | How you pay | Best for |
|---|---|---|
| LTE / 5G, capped | Monthly fee for a fixed data bundle; out-of-bundle or top-up data on top | Backup lines and light-use branches |
| LTE / 5G, uncappedMost common | Flat monthly fee, full speed up to a fair-use threshold, then throttled | Small offices without fibre |
| Fixed wireless (WISP) | Monthly fee by line speed; installation of the rooftop dish, sometimes on contract | Suburban, peri-urban and rural offices |
| Licensed microwave | Per-site quote for a dedicated link with an SLA | Sites that need fibre-grade reliability |
Of the South African providers in our fact base, eight publish an entry wireless price on their own websites. Those entry prices run from R219 to R735 a month, with a median of R395.50 (sampled to 29 October 2026). That is the cheapest plan each provider publishes: the entry speed differs by provider and technology, and some prices include VAT while others exclude it or don’t say, so compare like with like. It is the band a small business should expect to see for an entry line; faster, dedicated and SLA-backed products sit above it and are usually quoted. We do not print an “average business wireless price”: no provider publishes one, so the figure would be ours, not theirs. Per-provider rates are on the wireless comparison page.
Most “uncapped” LTE and 5G plans slow you down after a fair-use threshold, and the threshold and the throttled speed differ by provider and plan. For light office use you may never notice; for video calls, cloud backups or a busy VoIP line you will. Ask for both numbers in writing before you sign.
Read the fine print on “uncapped”: ask for the fair-use threshold and the speed you drop to after it, and whether the price includes VAT – published wireless prices are quoted both ways.
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:
Move the slider to the number of people who will share the connection. Bandwidth is rarely what breaks a wireless line; contention, jitter and the missing SLA are.
LTE jitter can break up calls when the tower is busy, so call-heavy teams should use 5G or fixed wireless, ideally with a second line for failover.
If all 10 were on VoIP calls at once, that is about 1 Mbps each way. A single VoIP call uses roughly 100 kbps in each direction.

WhichVoIP sells no internet. Every provider below has a published WhichVoIP score for its wireless service, highest first, on the same five measures: price, features, customer reviews, reliability and support. Sponsors are marked and scored exactly like everyone else. Use the checks above, then rank by the measure that matters most to you. To compare them side by side with published prices, use the wireless internet provider comparison.
8 and above6.5 to 7.9below 6.5– not enough reviews to score
These providers sell a real LTE, 5G or fixed-wireless product and are on many shortlists, but their WhichVoIP score is for a different service (shown in brackets), so they are listed here by fit rather than ranked against the providers above. Sponsors are marked.
These are reviewed on the same five dimensions but sit outside the shortlist for most business wireless buyers. They remain worth a look if one of them already serves your business: Herotel, MTN Business, Telkom, Supersonic and Cell C.

Among the eight South African providers that publish an entry wireless price, plans run from R219 to R735 a month, with a median of R395.50 (sampled to 29 October 2026). Faster, dedicated and SLA-backed products such as licensed microwave are priced per site on quote. Per-provider rates are on the wireless comparison page.
Inside strong metro 5G coverage it can be a practical primary line, with a faster install than fibre. Outside that coverage, and for anything latency-sensitive, fibre still wins on consistency and cost per Mbps. Test 5G at your exact address before relying on it.
Yes, for a small office on a good signal, with QoS on the router to prioritise voice. LTE jitter can break up calls when the tower is busy, so larger or call-heavy teams should use fibre, fixed wireless or 5G, ideally with a second line for failover.
It is the usage threshold after which an “uncapped” plan slows your connection. The threshold and the throttled speed differ by provider and plan, so ask for both in writing before signing, especially if you run video calls, cloud backups or VoIP.
Yes, and it is one of the best uses of wireless. An LTE, 5G or fixed-wireless line on a dual-WAN router fails over automatically when the fibre drops. Put the backup on a different network or technology from the fibre so one outage cannot take out both.
LTE and 5G run on the mobile networks’ towers and plug in with a SIM. Fixed wireless is a dedicated radio link from a wireless ISP’s tower to a dish on your roof, with steadier speeds and business SLAs. Licensed microwave is an uncontended point-to-point link with a hard SLA, priced per site on quote.
Your router needs backup power, and the tower needs its own: tower batteries last hours, not days, so long outages can take a tower down even when your office has power. A UPS on your equipment plus a second line on a different network or technology is the reliable setup.
On WhichVoIP’s published wireless scores: WIRUlink 7.4/10, Rain 7.0, SkyWire 6.9, Vodacom Business 6.7, Paratus SA 6.3 and Letaba Wireless Internet 6.0. Scores cover pricing value, feature set, customer reviews, reliability and support quality, and each links to its full review.
Everything here is drawn from primary sources: the pricing pages providers actually publish, the ICASA licensing framework, and our own catalogue of independent reviews and directory listings. A price appears on this page only if it is a published rate we have sampled and dated; where we cannot bind a figure to a provider’s own rate card, we leave it out rather than estimate it. Per-provider prices live on the wireless comparison page, which is refreshed from the same fact base.
The guide covers four technologies – LTE, 5G, fixed wireless access from regional WISPs and licensed point-to-point microwave – for business buyers. It excludes residential-only plans and satellite, which we cover separately.
Our provider reviews use a published score across five dimensions (pricing value, feature set, customer reviews, reliability and support quality), and every brand claim in a review is confirmed on the provider’s own website before it goes live. Sponsors are always disclosed and never move up the ranking.
