Starlink versus fibre: the Harare connectivity maths

Licensed in September 2024, Starlink outnumbered every Zimbabwean fibre ISP by early 2026. Quarterly figures, a cost table and a decision rule for Harare.

Six quarters that rewrote the market

POTRAZ issued Starlink two licences on 6 September 2024 — network services and national ISP — for US$575,000 in total. What followed is the fastest change in Zimbabwe’s fixed-internet market since fibre-to-the-home arrived.

Quarter	VSAT subscriptions (Starlink counted here)	Change
Q3 2024	3,814	—
Q4 2024	23,410	+513.8%
Q1 2025	30,907	+32.0%
Q3 2025	50,949	—
Q4 2025	67,057	+31.7%

For comparison, POTRAZ counted 79,416 fibre subscriptions and 102,105 fixed-LTE subscriptions at Q4 2024. By Q1 2026, Starlink subscriptions exceeded all local ISPs’ fibre subscriptions combined. In Q2 2025 Starlink’s roughly 40,000 users were already generating 83.9 PB of traffic — about a quarter of all fixed traffic — or ≈680 GB per user per month, against ≈490 GB for the average fixed subscription and ≈3.8 GB for mobile.

Prices moved too. Before September 2024 a family fibre package cost at least US$150–200 a month; Starlink’s Mini plan lists at just over US$30 and the Standard residential plan just over US$50; ISPs have since recalibrated with packages from around US$90. (Business plans and kit prices vary; check current lists.)

What Starlink did not change

Latency and jitter. Satellite links are fine for WhatsApp, email, cloud apps and video calls, and worse than fibre for anything that needs steady low latency — a PBX trunk, a point-of-sale link that times out aggressively, a live fiscal-device sync under load. Fibre where it is trenched remains the better primary for those.

Power. A Starlink kit needs mains or an inverter, as does a fibre ONT. In the January 2025 pattern of cuts from 4am to 10pm, both are off unless you put them on backup. Neither technology solves the load-shedding problem; it just moves the question to the inverter.

Data residency. If your policy says customer data stays in Zimbabwe, the answer is colocation at Africa Data Centres’ Harare facility (the only carrier-neutral option we can source in the city), reached over either link. Starlink does not make an in-country cloud region appear; there is none.

The customer’s side. Your office may now have 680 GB a month. Your customer still has 3.8 GB. Nothing about Starlink changes the rule that customer-facing automation belongs on WhatsApp.

The cost table (illustrative)

Round numbers for a 20-person Harare office, monthly, USD, September 2026 list prices as reported above. Your quotes will differ; the shape will not.

Option	Monthly cost (illustrative)	Bandwidth ceiling	Fails when	Best for
Fibre only (business package)	~90–200	High, symmetric where offered	Trench cut, ISP outage, power at the ONT	CBD, Avondale, Msasa where trenched; PBX, POS
Starlink only (standard)	~50	~680 GB/user observed; shared kit	Heavy rain fade, power at the kit, obstructed sky	Borrowdale stands and suburbs without fibre
Fibre primary + Starlink failover	~140–250	High, with automatic fallback	Only when both fail — different technologies, different failure modes	Any office where the automation must not stop
Mobile-data hotspot only	~30–60 per heavy user	3.8 GB average plan; quickly expensive	Bundle exhaustion mid-month	One-person businesses; the stall; the driver

The row that matters is the third. A fibre trench and a satellite dish do not fail together; a fibre trench and a second fibre trench from the same ISP often do. Dual-WAN routers that fail over automatically are commodity equipment; the marginal cost of resilience is the Starlink subscription, roughly the price of one staff lunch a day.

A decision rule

Is fibre trenched to the building? If no: Starlink primary, mobile-data hotspot as failover for the two people who must not go offline.
If yes: what runs on the link that needs low latency? PBX trunk, POS, fiscal-device sync, video conferencing for the boardroom. If any: fibre primary.
Does any customer-visible automation depend on the office link? It should not (see the stack design). If it does, add Starlink as failover today and fix the design this quarter.
Put both the ONT and the Starlink kit on the inverter circuit and measure how many hours that circuit lasts. That number, not the bandwidth, is the real capacity of the office.
Review at each POTRAZ quarterly report. The market has moved 30% a quarter for six quarters; the price list you signed is already out of date.

What to watch next

POTRAZ’s next sector reports: whether fibre subscriptions fall or ISPs hold with cheaper packages; TelOne has announced a large fibre-to-the-home expansion that would change the trenched footprint in Harare’s suburbs.
5G: Econet held 91.3% of the country’s 5G base stations in the quarter to May 2025 and added 100 sites in that quarter, with the CBD, Avondale and the airport covered early. A 5G fixed-wireless product would be a fourth column in the table above.
POTRAZ’s own use of Starlink — 98 community digital centres upgraded by mid-2026 — as a signal that the regulator sees satellite as infrastructure, not a competitor to be contained.
