Senegal's mobile lines rose 4.3% from a year earlier to 24.83mn at the end of June 2026, while Yas lifted its market share to 24.35% from 22.92% and Orange's share slipped to 55.17% from 55.62%, telecoms regulator ARTP said in its quarterly dashboard. Expresso's share fell to 14.95% from 16.12%.
Analysis: Yas added an estimated 590,000 lines over the year, growth of 10.8%, compared with 3.4% for Orange, by our calculation. Its advance was more pronounced in voice traffic: Orange's share of outgoing calls fell two percentage points to 69.53%, while Yas gained 3.3 points. That suggests Yas is gaining usage, not merely secondary SIM registrations. Sonatel, which operates Orange, nevertheless reported a 12.9% increase in nine-month profit, supported by data and mobile money—businesses not captured by voice market share. ARTP's third-quarter figures will test whether the shift continued through September.
