Free calls, dead voice and Shameel Joosub’s Spanish ghost

South African bank-backed mobile virtual network operator (via Cell C) now offers free on-net calls between its subscribers. The move is analyzed as less disruptive than it appears: voice revenue has already collapsed due to WhatsApp and data-driven communication, making the marginal cost of on-net calls near zero. The piece examines the broader structural decline of voice as a revenue category for South African mobile operators, the economics of termination rates, and the ongoing debate about whether regulators should ease pressure on operators to protect network investment. It concludes that operators must find new revenue above the connectivity layer — including financial services — as data itself commoditizes.
