The Connectivity Decision Every SA Business Faces

Choosing the right internet connection for your South African business used to be simple: you got a Telkom ADSL line and moved on. Those days are gone. Today, SMEs face a connectivity landscape with three primary options — fibre, 5G, and LTE — each with distinct trade-offs in speed, reliability, cost, and deployment time.

The wrong choice costs you in two ways: overpaying for capacity you don't need, or losing productivity because your connection can't handle your workload. This guide breaks down each option with real SA pricing, performance data, and use-case recommendations.

Fibre: The Gold Standard

Fibre optic connectivity is the benchmark for South African business internet. It offers symmetrical (or near-symmetrical) speeds, the lowest latency, and the highest reliability. Once installed, it simply works — there's no signal degradation, no weather interference, and no congestion from too many users on the same tower.

SA Fibre Providers

  • Vumatel: Widespread in Gauteng and Western Cape. Business tiers up to 1 Gbps. R899-R2,499/month for business plans.
  • Openserve (Telkom): National footprint, including smaller towns. R599-R1,899 for business plans. Good for firms outside major metros.
  • Metro Fibre: Strong in business parks and industrial areas. R799-R1,999/month.
  • Link Africa: KwaZulu-Natal focused, expanding nationally. R699-R1,799/month.

When to Choose Fibre

  • Your office is fixed and you don't plan to move within 12 months.
  • You have 10+ users on the network simultaneously.
  • You run cloud-based applications (VoIP, cloud accounting, practice management).
  • You upload large files regularly (design firms, architects, legal conveyancing with large document sets).
  • You need a VoIP phone system — fibre's low latency makes it ideal for CloudPBX.

The Drawback

Installation time. If your premises aren't already lit for fibre, you're looking at 2-6 weeks for trenching, ONT installation, and activation. In some business parks, this can stretch to 8 weeks if wayleave approvals are slow. Plan ahead.

5G: The Flexible Option

5G has changed the SA connectivity landscape dramatically since Vodacom and MTN rolled out their networks in 2022-2023. For businesses that need fast connectivity without waiting for fibre installation — or that operate from temporary locations — 5G is a genuine alternative.

SA 5G Providers

  • Vodacom 5G Business: 50-300 Mbps. R699-R1,299/month. Strong coverage in Johannesburg, Pretoria, Cape Town, Durban.
  • MTN 5G Business: 50-250 Mbps. R599-R1,199/month. Expanding coverage in major metros.
  • Rain 5G: 30-200 Mbps. R599-R999/month. Consumer-focused but usable for small offices.
  • Telkom 5G: 50-300 Mbps. R599-R1,299/month. Growing footprint.

When to Choose 5G

  • You need connectivity within days, not weeks.
  • Your business is mobile or in a temporary location (construction sites, pop-up retail, events).
  • Fibre isn't available at your premises and won't be for 3+ months.
  • You want a backup connection that's independent of your fibre line.

The Drawback

5G performance depends on tower proximity and network congestion. A business 200m from a 5G tower will see excellent speeds; one 3km away may see 5G drop to LTE speeds during peak hours. Also, 5G towers need municipal power — during load shedding, performance can degrade if the tower's backup batteries run out. Check with your provider about tower backup power.

LTE: The Reliable Backup

LTE (4G) is the workhorse of SA business connectivity — not because it's the fastest, but because it's the most widely available and the most affordable. For most SMEs, LTE's role is as a failover connection: when your primary fibre or 5G line goes down, LTE takes over automatically so your business stays online.

SA LTE Providers

  • MTN LTE Business: 10-100 Mbps. R299-R699/month. Best national LTE coverage.
  • Vodacom LTE: 10-80 Mbps. R299-R599/month. Strong in urban areas.
  • Telkom LTE: 10-100 Mbps. R299-R899/month. Often the cheapest option, good in Telkom-served areas.
  • Cell C LTE: 10-50 Mbps. R299-R499/month. Budget option for low-use sites.

When to Choose LTE

  • You need a failover/backup connection for your fibre or 5G.
  • Your business has minimal connectivity needs (under 5 users, basic email and web).
  • You need connectivity at a remote site where neither fibre nor 5G is available.
  • You're a solo professional working from home and just need email plus light browsing.

Load Shedding Considerations

Load shedding remains a factor in connectivity decisions. Here's how each option fares:

  • Fibre: The fibre network itself is generally unaffected, but your ONT (fibre modem) needs power. A basic R600-R1,200 UPS will keep you online for 2-4 hours of load shedding.
  • 5G/LTE: Towers have backup batteries, but these typically last 2-4 hours. During Stage 4+ load shedding, expect degraded mobile network performance as towers cycle through outages.
  • CloudPBX: If you're running VoIP, ensure your router and ONT are on UPS power. CloudPBX calls route through our cloud infrastructure, so even if your office loses power, calls can failover to your mobile.

The Bottom Line

For most SA SMEs in fixed offices, fibre with LTE failover is the right answer. It gives you the speed and reliability for daily operations, with a backup that kicks in automatically when needed. 5G is the best choice for temporary or mobile operations, and as a fibre alternative where fibre isn't available. LTE remains the cost-effective failover and low-use option.

Don't overpay for speed you won't use, and don't cut corners on reliability if your business depends on being online. Match your connectivity to how your business actually works.
