Screamer Telecoms Review
A buyer-focused look at Screamer Telecoms – the Centurion-based independent Gauteng ISP that wraps voice, hosted PBX, Microsoft Teams calling, fibre, wireless WAN and LTE/5G onto a single in-house WAN, with a published uptime guarantee that bundles a backup microwave link with business fibre.
Is Screamer Telecoms worth shortlisting?
Yes for Gauteng businesses and households that want voice and internet from one independent operator, with call-quality riding the carrier’s own backbone and an unusual bundle: a backup microwave link included with the fibre product. Voice rates (Cloud PBX from R199/user, the standalone voice line from R116/month) sit in mid-market territory rather than the cheapest tier. Buyers outside the province or chasing the lowest per-seat rate should weigh alternatives.

An independent Centurion operator that puts voice and Microsoft Teams calling on a single in-house WAN and ships a complimentary backup microwave link with business fibre.
Screamer has been in market for more than two decades. The hook for buyers is that voice (hosted PBX, the standalone VoIP line, Teams calling) rides the carrier’s own QoS-managed backbone rather than as a best-effort overlay on a third party. The published uptime guarantee adds a backup microwave link to high-speed business fibre at no additional monthly charge; the provider claims this bundle isn’t matched by peers at the same price band. Public feedback is split across channels at small samples: HelloPeter sits at 4.11★ across 19 reviews with a 73.7% five-star share and a #10 ISP placement; the Centurion Google profile sits at 2.4★ across 8. Read both before deciding.
Is Screamer Telecoms likely to suit you?
Good fit: Gauteng buyer wanting voice + connectivity from one in-house operator.
Pros and watch-outs
What Screamer does well, and where the Gauteng footprint and split-channel review picture shape the fit.
- Voice on the operator’s own QoS-managed backbone rather than as a best-effort overlay on a third-party connection. Hosted PBX (Starter R199/user, Business R299/user), the standalone VoIP line (R116/month) and Microsoft Teams calling are all part of the lineup alongside fibre, wireless and LTE/5G.
- Uptime guarantee bundles a complimentary backup microwave link with high-speed business fibre at no additional monthly charge – positioned as not matched by peers at the same price band, with rollout often within 48 hours of address confirmation.
- Twenty-plus years in the market, independent positioning (not reseller), Centurion-based operations and field support across the province.
- HelloPeter feedback skews positive at the available volume: 4.11★ across 19 reviews with a 73.7% five-star share and a #10 SA ISP placement. The dominant voice is positive even with a 21.1% one-star minority on evening-peak congestion themes.
- Wide product surface for an independent: residential fibre and mobile data alongside the business stack, Microsoft 365 support, network security and VPN solutions as MSP add-ons.
- Public review signals point in different directions at small sample sizes – the two main channels diverge sharply (positive on HelloPeter, weaker on the Centurion Google profile). Read both before deciding and ask sales for customer references at your stage.
- Voice rates aren’t the cheapest in the market – the published Cloud PBX tiers sit between low-cost SA operators and the larger telcos’ enterprise rates. The differentiation is the bundled package, not the headline per-seat number.
- Coverage is Gauteng-anchored. Outside the province the connectivity-and-voice bundle gets harder to deliver as a single-operator package – verify at the address before committing.
- HelloPeter average response sits at 58.5 hours, which is slow even allowing for the low review count. Confirm escalation paths and credit triggers in writing at quote.
Score breakdown
Four categories that decide whether Screamer is the right SA operator for your business or home – weighted to the buying evidence a South African buyer actually uses.
Hosted PBX Starter at R199/user, Business at R299/user and the standalone VoIP line from R116/month are all on the public catalogue. Mid-market positioning rather than lowest-cost – the integrated voice-and-WAN package is what’s being sold, not a discount per-seat rate.
Voice (hosted PBX + VoIP line + Teams calling) on the operator’s own backbone, business fibre, wireless WAN, LTE/5G, residential fibre, mobile data, Microsoft 365 support, network security, VPN solutions and a backup microwave link bundled with business fibre.
Twenty-plus-year operating record + in-house voice WAN + bundled backup link anchor the reliability side. Public signals split: HelloPeter 4.11★ / 19 (positive at small volume, #10 placement, 6.8 Trustindex) vs Google 2.4★ / 8 (weaker at small volume, 58.5hr HelloPeter reply average).
Voice tier rates published with named tiers, service-term framing surfaced openly, the bundled-backup offer explicitly disclosed, independent-operator positioning declared. Gauteng coverage stated honestly – sales handles per-premises availability.
Pricing – voice tiers public, connectivity sales-scoped per premises
Voice rates are on the public catalogue. Business fibre, wireless WAN and LTE pricing surfaces once sales has scoped the premises and speed tier. The bundled backup-link deal is positioned as included at no additional monthly charge under the service terms.

What real customers say
Screamer shows a split-channel public picture at small sample sizes. HelloPeter sits at 4.11★ across 19 reviews over the last twelve months, ranked #10 in SA ISPs, with 73.7% five-star and a vocal 21.1% one-star minority focused on evening-peak congestion. The Centurion Google profile sits at 2.4★ across 8 reviews with a similar congestion theme. Response time on HelloPeter averages 58.5 hours, which is slow.
4.11 stars across 19 reviews in the last twelve months, ranked #10 in SA Internet Service Providers, 6.8 Trustindex. Distribution: 73.7% five-star + 5.3% four-star + 21.1% one-star – the dominant voice is positive even with a meaningful complaint minority on evening-peak congestion.
2.4 stars across 8 reviews at the Sterling Industrial Park head office. Small volume but the directional read is weaker than the HelloPeter channel. A recent verbatim from a Local Guide customer of multi-year standing references degraded support response between 2025 and the current period.
Honest reading: weigh the positive HelloPeter feed and the weaker Google sample together rather than picking one as primary. Both samples are small enough that direct customer-reference checks add more decision value than star averages alone.
Buyer move: ask Screamer for two current customer references in your suburb at the speed tier and product mix you’re shortlisting before committing – small-sample public reads benefit from direct call diligence as a hedge.
The Screamer service surface
An unusually wide lineup for an independent SA ISP – connectivity, voice, MSP services and a bundled-backup deal on one operator’s footprint.
Hosted PBX + VoIP line + Teams calling
Hosted PBX in Starter (R199/user) and Business (R299/user) tiers, the standalone VoIP line from R116/month and Microsoft Teams calling. Voice rides the operator’s own QoS-managed backbone rather than as a best-effort overlay on a third party.
Business fibre with complimentary backup link
High-speed business fibre paired with a microwave backup link included at no additional monthly charge under the service terms. Positioned as not matched by peers at this price band, with rollout often within 48 hours of address confirmation.
Business fibre + wireless WAN + LTE/5G + residential
Business fibre (FTTB / DIA), wireless WAN for multi-site setups, LTE/5G internet, residential fibre and mobile data – all on the same operator and account. Static IP available on the business side.
Microsoft 365 + network security + VPN
Microsoft 365 support, network security and VPN solutions layered onto the connectivity stack. Useful for buyers consolidating connectivity, voice and IT-managed services with a single supplier.
Own infrastructure, not a reseller
Provider explicitly states “Independent ISP – not a congested reseller. We operate our own network.” Twenty-plus years in the market with Centurion-based operations and Gauteng field support.
Credits and clear contract wording
Site language commits to “transparent SLAs and credits” with the uptime guarantee’s scope defined in the contract terms. Worth pulling the service-level document at quote so the credit triggers and measurement window are clear before signing.
You’re a Gauteng-based business or household wanting voice and internet from one independent operator running its own backbone.
- Your premises are in Gauteng and you want voice on the same WAN as the line – not as a best-effort overlay on someone else’s connection.
- A bundled backup link with high-speed business fibre would change your resilience picture, especially through load-shedding and primary-link incidents.
- You’re already on Microsoft 365 and want Teams calling from the same supplier as the connectivity.
- An independent-operator positioning and SLA-backed call quality matter more to you than the cheapest per-seat rate in the market.
Your situation falls outside what Screamer is built for – another SA provider will fit better.
- You’re outside the Gauteng coverage footprint: the connectivity-and-voice bundle gets harder to deliver as a single-operator package nationally. Confirm at the address before committing.
- You want the absolute cheapest per-seat hosted PBX rate: Euphoria Telecom publishes from R65 per extension and sits at the lowest-cost end of the SA market.
- You want the strongest single-channel customer-feedback signal: Saicom Voice sits at 4.6★ / 110 with named direct interconnects and SA enterprise references.
- You need pan-African or Microsoft Operator Connect at scale: MTN Business or Vodacom Business surface those lines directly.
Alternative providers to compare
Two SA operators worth quoting alongside Screamer Telecoms.
Saicom Voice
SA Tier 1 voice with 16 named direct interconnects and the strongest customer-feedback signal in the WhichVoIP corpus (4.6★ / 110 reviews plus named SA enterprise references). Strong cross-comparison for voice-led B2B buyers.
Switch Telecom
SA voice and PBX specialist with Microsoft Teams calling published. The right Teams-led alternative for buyers whose Microsoft 365 environment is the procurement anchor.
South African essentials
Four SA-specific signals to verify before signing.
Screamer Telecoms operates as a licensed SA electronic communications service (ECS) provider with an electronic communications network services (ECNS) footprint behind the in-house infrastructure claim. Verify the operating-entity name and licence references at register.icasa.org.za if procurement requires it.
Coverage is Gauteng-anchored. Run the address check on screamer.co.za to confirm which combination (fibre, wireless WAN, LTE/5G) reaches your specific premises and whether the bundled backup link is available there.
The uptime guarantee references “guarantee and money-back eligibility defined by the SLA and service terms.” Pull the contract document at quote so the credit triggers, measurement window and remedy path are clear before signing.
Public review signals split between the two main channels at small volume. Ask sales for two current customers in your suburb at the speed tier and product mix you’re shopping, and call at least one before contracting.

- 20 May 2026Score recalibrated from 7.4 to 7.2 against the updated 4-axis rubric. Feature set lifted to 8.0 on the now-surfaced uptime guarantee that pairs a complimentary backup microwave link with high-speed business fibre – not captured in the prior review. Support and reliability adjusted to 6.5 honestly reflecting the split-channel public picture (HelloPeter 4.11★ / 19 positive vs Google 2.4★ / 8 weaker, at small samples). Pricing positioning kept at mid-market (R199 Starter / R299 Business / R116 standalone line) with the integrated bundle as the differentiator rather than a discount per-seat rate.

FAQ
Short answers for the questions buyers typically ask before requesting quotes.
What is Screamer Telecoms?
An independent South African ISP and voice operator based in Centurion (Sterling Industrial Park, Olievenhoutbosch). In market for more than two decades, positioned as an independent operator running its own backbone – not a reseller – with voice, fibre, wireless WAN, LTE/5G and managed IT services on a single operator footprint.
What’s the difference between Cloud PBX Starter and Business?
Starter sits at R199 per user and Business at R299 per user. The Business tier carries deeper feature scope – ask sales for the per-tier feature matrix and confirm concurrent-call licensing, queues, IVR, call recording and the Teams calling add-on for the tier you’re shopping.
Does Screamer offer SLAs on voice services?
Yes – site language commits to “transparent SLAs and credits” with the uptime guarantee’s scope defined in the service terms. Pull the contract document at quote so the credit triggers, measurement window and remedy path are clear before signing.
What is the uptime guarantee?
A published bundle that pairs a complimentary backup microwave link with high-speed business fibre at no additional monthly charge under the service terms. The provider positions this as not matched by peers at the same price band, with rollout often within 48 hours of address confirmation.
Can I use Screamer for Microsoft Teams calling?
Yes – Teams calling sits in the voice catalogue alongside hosted PBX and the standalone VoIP line. Quote-driven on the SBC delivery model, M365 plan inclusion and calling-plan scope. Useful for buyers who want Teams calling from the same operator as the connectivity.
Can I take voice without buying connectivity from Screamer?
Voice services are standalone in the catalogue. The structural value of the offering, however, is voice on the in-house QoS-managed backbone – running voice over a third-party connection forgoes the on-network advantage. Confirm with sales whether the service terms change when voice rides external connectivity.
What is Screamer’s geographic coverage?
Gauteng-anchored on most service lines, with national reach on certain product surfaces. Run the address check on screamer.co.za to confirm which combination of fibre, wireless WAN, LTE/5G or residential fibre reaches your specific premises.
Does Screamer include number porting?
Number porting is part of the voice service flow – confirm timelines and any per-number admin fees with sales before signing. Porting is standard practice across SA voice operators but can vary on lead time depending on the donor carrier.
