Dedicated versus shared is the question to ask
Stem Connect offers fibre in two shapes, and the difference decides both price and behaviour. A shared access line divides capacity between users on the same infrastructure, which is fine for most offices and cheaper. A dedicated line reserves capacity for you alone, costs considerably more, and is the right answer when a slow afternoon costs real money. Establish which is being quoted before comparing anything, because the two are not competing products. The three-country footprint across South Africa, the UK and Ireland suits a business with operations in more than one of those markets, and multi-site network design is named as a distinct service for exactly that reason. On voice, the site is careful to say cloud voice is available in selected markets, so confirm your sites are covered rather than assuming. Compare alternatives in the fibre provider directory.
Who Stem Connect is a fit for
- Businesses operating in South Africa plus the UK or Ireland
- Companies needing dedicated rather than shared fibre capacity
- Multi-site operations wanting network design rather than separate lines

What is the difference between dedicated and shared fibre access?
Shared access divides capacity between users on the same infrastructure and costs less. Dedicated access reserves capacity for you alone and costs more. Ask which is being quoted, because comparing a dedicated price against a shared one is not a like-for-like comparison.
Which countries does Stem Connect operate in?
The site names South Africa, the United Kingdom and Ireland. Ask who provides local support in each market and whether the same service levels apply.
Does Stem Connect offer phone services?
The site describes cloud voice options where available in selected markets rather than as a standard product. Confirm whether voice is offered for your specific sites before treating this as a telephony supplier.
Where is Stem Connect based?
No address is published on the site. The company’s Google profile places it at 105 Club Avenue, Waterkloof Heights, Pretoria.
Does Stem Connect cover my address?
The site describes availability as address-dependent and publishes no coverage map. Ask for an address-level check for each site you need connected.
What does it cost?
No pricing is published. Ask for the monthly charge per site naming whether it is dedicated or shared, the installation cost, and the contract term as separate figures.
