The numbers tell a compelling story about where MTN Group is making its most profitable moves across Africa. Ghana has emerged as the telecom giant's most valuable market per customer, generating an average revenue per user (ARPU) of $6.76 in 2025 — nearly double Nigeria's $3.60.
This revelation comes from MTN Group's 2025 data sheet, which shows how currency stability is reshaping the telecom business model across Africa. Notably, how Ghana's smaller subscriber base is generating more value per customer than MTN's traditional powerhouse markets.
Currency Stability Drives Ghana's Success
MTN Ghana's impressive performance stems from macroeconomic stability that allowed the company to retain value in dollar terms. The Ghanaian cedi strengthened by approximately 40% against the dollar in 2025, closing at GHS10.45/$ compared to GHS14.7/$ in 2024.
Inflation also cooperated, declining dramatically from 23.5% in January to just 5.4% in December 2025. This stability translated directly into operational efficiency.
MTN Ghana's service revenue rose 36.2% in 2025, while earnings before interest, tax, depreciation and amortisation (EBITDA) climbed 43.5%. The operation now runs at 60.1% margins — more profitable than MTN Nigeria's recovered 52.7% margins.
Nigeria Still Brings Volume Despite Challenges
Nigeria remains MTN's growth engine by sheer scale. With 87.3 million subscribers, MTN Nigeria generated ₦5.2 trillion ($3.77 billion) in service revenue, accounting for over a quarter of the group's total ZAR218.50 billion ($12.21 billion) revenue in 2025.
The Nigerian operation showed remarkable recovery, with revenue rising 55.1% in 2025 and profit after tax rebounding to ₦1.11 trillion ($803.89 million), reversing the previous year's losses. Much of this growth came from tariff adjustments and increased data usage.
However, macroeconomic headwinds continue to erode gains in dollar terms. While the naira strengthened to around ₦1,400/$ in 2025 from ₦1,500/$ in 2024, it remains far from the sub-₦1,000/$ levels held before 2024. Inflation closed 2025 at 15%, still in double digits.
A Strategic Shift in Focus
These numbers highlight a fundamental shift in MTN's business model. The group is discovering that value no longer comes purely from its largest markets, but from those offering currency stability and pricing power.
MTN Nigeria overtook South Africa to become the group's largest profit contributor in 2025, but Ghana's efficiency metrics suggest a different path forward. The smaller market is converting macroeconomic stability into higher, more predictable earnings per subscriber.
For investors watching African telecom trends through our coverage, Ghana's performance demonstrates how currency volatility and inflation can make or break subscriber value. Size matters, but sustainability matters more.
This trend will likely influence where MTN and competitors focus their expansion efforts. Markets with stable currencies and controlled inflation suddenly look more attractive than pure subscriber volume plays, reshaping the African telecom investment landscape.
