Network Computer Wireless works from Piet Retief Boulevard in Vanderbijlpark, supplying IT support, hardware and network infrastructure to businesses and households across the Vaal Triangle and beyond.

Key facts
| Who they are | A Vanderbijlpark technology company providing, in its own description, a full range of IT solutions, hardware supply and network infrastructure services for businesses and individuals across South Africa |
| Voice services | VoIP systems, supplied as one line within a broad IT services catalogue |
| Also offers | IT support and repairs, computer maintenance, business managed support, network cabling, internet connectivity, cloud servers, Microsoft 365, security camera installation, website design, web hosting and printer supplies |
| Head office | 121 Piet Retief Boulevard, Vanderbijlpark South East 1, Vanderbijlpark, 1911, Gauteng |
| Coverage | The company states it serves customers across South Africa, with the physical presence and the bulk of its customer feedback concentrated in the Vaal Triangle |
| Customer rating | 4.8 from 284 Google reviews — by a wide margin the largest sample of any provider in this batch, on a profile matching both the domain and the street address. One caveat matters when reading it: the reviews overwhelmingly describe computer repair, IT support and hardware work rather than telephony. The score is a fair reflection of the business, not specifically of its VoIP offering |
| What that means for you | A strong local IT reputation is genuinely useful when your phone system runs over your own network, because most day-one voice problems are network problems. It is not the same thing as deep telephony experience, so ask how many VoIP installations they have done and which platform they deploy |
| Pricing | Quote-based. No rand figures are published for VoIP or any other service |
| ICASA licence | No ICASA reference is published. For a reseller supplying hosted voice this is normal, since the licensed capacity sits upstream — ask which operator carries the calls |
| Founded | Not publicly stated. No founding year appears on the website |

A strong local IT reputation, applied to phones
Two hundred and eighty-four reviews at 4.8 is a serious body of local evidence, and there is no equivalent for most providers in this directory. Read what it actually covers though. The feedback describes computer repairs, IT support and hardware rather than phone systems, so it tells you this is a well-regarded technology business in the Vaal Triangle rather than that it is a proven telephony specialist. That distinction is less damaging than it sounds. Cloud voice runs over your own network and switches, and a large share of the problems that get blamed on a VoIP provider are really cabling, router or bandwidth problems. A company that does your cabling, your network and your support is well placed to fix those quickly, and being twenty minutes away rather than in Johannesburg matters when someone has to physically attend. Do the telephony-specific diligence anyway: ask how many VoIP systems they have deployed, which platform they use, which licensed operator carries the calls, and what happens to call quality when your line is saturated. If the answers are specific and the local support is as good as the reviews suggest, the combination is a strong one for a Vaal Triangle business. Compare voice specialists in the VoIP directory.
Who Network Computer Wireless is a fit for
- Vaal Triangle businesses wanting a nearby supplier who can attend site quickly
- Companies that want the cabling, the network and the phone system handled by one team
- Small businesses without internal IT needing support across hardware, cloud and voice

Because the phone system will run over your own network, ask them to quote the cabling and switching alongside the voice rather than treating them separately. Then do the telephony-specific checks: how many VoIP systems they have deployed, which platform, which licensed operator carries the calls, and what happens to call quality when the line is busy.
