Dedicated Internet vs Leased Line South Africa 2026 — What SA Businesses Need to Know

Bottom line: For most South African businesses, Dedicated Internet Access (DIA) is the right choice — uncontended, symmetrical fibre from R1,999/month with a 99.9% SLA. Leased lines are only needed when you require a private Layer 2 circuit between sites (think banking, multi-branch MPLS, or healthcare). MWCom provides both.

The Short Answer
Dedicated Internet Access (DIA) and leased lines are both uncontended, business-grade connections — but they serve different needs and come at very different price points. In South Africa, most businesses with 5-100 staff need DIA. Leased lines are for large enterprises that need private Layer 2 connectivity between sites.
What Is Dedicated Internet Access?
Dedicated Internet Access means you get a fixed, unshared portion of bandwidth connecting you directly to an internet exchange point. Unlike ADSL or consumer fibre — where bandwidth is split between thousands of users — DIA guarantees your contracted speed at all times.
- Uncontended: Your 100Mbps is always 100Mbps, even at 9am on a Monday.
- Symmetrical: Upload and download speeds are identical — critical for VoIP, cloud backups, and video conferencing.
- SLA-backed: Business-grade SLAs with guaranteed uptime and defined response times.
- Public IP: Traffic routes over the public internet.
What Is a Leased Line?
A leased line is a private, point-to-point circuit between two locations — typically between your office and a data centre, or between two offices. It does not connect to the public internet.
- Private Layer 2 circuit: Traffic never traverses the public internet.
- Multi-site connectivity: Ideal for MPLS networks spanning Johannesburg, Cape Town, and Durban offices.
- Enterprise pricing: Typically R8,000-R25,000/month depending on distance and capacity.
- Long lead times: Installation takes 6-12 weeks on average.
Dedicated Internet vs Leased Line: Side-by-Side Comparison
| Factor | Dedicated Internet (DIA) | Leased Line |
|---|---|---|
| Traffic type | Public internet | Private circuit |
| Typical use case | Cloud apps, VoIP, remote work | Multi-site MPLS, private WAN |
| South Africa pricing | From R1,999/month (MWCom) | R8,000-R25,000/month |
| Installation time | 5-15 business days | 6-12 weeks |
| Contention | None — fully uncontended | None — fully uncontended |
| Uptime SLA | 99.9% (MWCom) | 99.9%-99.99% |
| Suitable for | SMEs, 5-500 staff | Enterprises, multi-site |
Which One Does Your Business Actually Need?
You need Dedicated Internet Access if:
- You use Microsoft 365, Google Workspace, or any cloud-based ERP
- Your team makes VoIP or video calls throughout the day
- You have one office location (or branches that operate independently)
- You want fast installation and predictable monthly costs
You need a leased line if:
- You have multiple offices that need to share private data securely (banking, healthcare, legal)
- You are running MPLS or SD-WAN across sites
- Your compliance requirements prohibit traffic traversing the public internet
For the vast majority of South African businesses — especially SMEs in Johannesburg, Cape Town, Durban, and Pretoria — Dedicated Internet Access is the correct and far more cost-effective choice.

Why SA Businesses Are Moving Away from Leased Lines
Three factors have disrupted the leased line market in South Africa:
- Fibre rollout: Vumatel, Openserve, and Frogfoot now cover over 1.2 million business premises. Dedicated fibre replaces expensive TDM circuits in most cases.
- SD-WAN adoption: Enterprises can build secure private overlay networks over multiple DIA connections — achieving leased-line security at 40-60% lower cost.
- Cloud-first workloads: If your data is in Microsoft Azure or AWS, a leased line to a data centre adds latency without improving security.
Frequently Asked Questions
Is dedicated internet the same as leased line?
No. Dedicated Internet Access provides uncontended access to the public internet. A leased line is a private circuit between two physical locations that does not touch the public internet. Both are uncontended and business-grade, but they serve different purposes.
How much does dedicated internet cost in South Africa?
In 2026, dedicated internet in South Africa starts from R1,999/month for a 10Mbps uncontended line through providers like MWCom. Enterprise speeds of 100Mbps range from R5,499/month depending on location and provider.
What is the difference between dedicated and shared internet?
Shared internet splits bandwidth between multiple users — your actual speed may drop during peak times. Dedicated internet is 1:1 — your contracted bandwidth is always yours regardless of what other users are doing.
What speed of dedicated internet does my business need?
Allow 2-5Mbps per concurrent user. A team of 20 doing standard cloud work needs 40-100Mbps DIA. Add VoIP (1Mbps per call) and video conferencing (3-5Mbps per call). MWCom offers free capacity planning consultations.
Do I need a leased line for my Johannesburg and Cape Town offices?
Not necessarily. An SD-WAN solution built over two DIA connections with encrypted tunnels delivers near-leased-line security at 40-60% lower cost. Contact MWCom to scope the right solution for your multi-site setup.
