Cell C's 5G network is live and customers can use it today, CEO Jorge Mendes told TechCentral on Friday, and only because he was asked directly. There was no launch event and no mention of it in the company's full-year results published the same morning.

Any Cell C customer holding a 5G handset in a 5G coverage area is already on it. What is missing is the commercial proposition, which is precisely why the company has said nothing.

The coverage claim is the striking part. Cell C roams on both Vodacom and MTN rather than running its own radio network, so it reaches both operators' 5G sites across the 2.6GHz and 3.5GHz bands.

Mendes says that gives it the widest 5G footprint in the country. It now runs on roughly 28,000 roamed sites against the 5,500 it once owned, and spent R810-million on capital expenditure for the year, guiding R750-million to R850-million for FY2027, a fraction of what the larger operators commit.

The results underneath: revenue up 14% to R12.64-billion, adjusted EBITDA up 17% to R2.38-billion, net debt down 64% to R2.02-billion, and 1.3 million subscribers added to reach 8.9 million. Wholesale service revenue grew 20% to R1.76-billion across 5.71 million MVNO lines, an estimated 80% to 85% of the local MVNO market.

TechCentral reported the switch-on and Mendes's argument that 5G on its own is not a consumer proposition, since a video plays the same way it did on 4G. Business Day noted headline earnings per share rose 57.4% and the share gained on results day. ITWeb reported 69% growth in gross additions through indirect channels and the January launch of Cell C Business for SMEs.

Two things worth taking from this. Cell C claims the widest 5G coverage in South Africa, on R810-million a year while the incumbents spend billions, and the numbers say the model holds.

Its fastest-growing customers are not even its own, with MVNO data traffic up 131% against 47% group-wide, meaning Capitec and FNB subscribers are pulling harder than its retail base. The second is the restraint.

Mendes has the coverage and will not launch until he has something to sell, saying plainly that 5G does nothing a customer's 4G did not. Most companies ship the capability and invent the reason afterwards. Doing it the other way round looks like judgement rather than delay.
