Analyst Opinion

The use of classic voice telephony over public telephone networks is increasingly being replaced by voice and video calls over the internet. This development, alongside more and more affordable prices for voice calls over the internet – often already a part of data package deals –, is leading to a decline in revenues within this segment in all regions. Worldwide, the mobile voice segment reports the largest decline in revenues within the communication services market. However, because of the importance placed on everyone having a smartphone, profit is expected to be much greater than in the landline voice segment in the future.


Data coverage:

The data encompasses B2B and B2C enterprises. Figures are based on the revenues of telecommunications providers generated by end consumers and enterprises.

Modeling approach / Market size:

Market sizes are determined through a bottom-up approach, building on a specific rationale for each market segment. As a basis for evaluating markets, we use financial statements of key players, national statistical offices, and telecommunications regulatory authorities. In addition, we use relevant key market indicators and data from country-specific associations, such as the number of fixed broadband subscriptions, the number of telephone subscriptions, the number of mobile broadband connections, the number of cellular subscriptions, and the GDP. This data helps us estimate the market size for each country individually.


In our forecasts, we apply diverse forecasting techniques. The selection of forecasting techniques, such as exponential trend smoothing, is based on the behavior of the relevant market.

Additional notes:

The data is modeled using current exchange rates. The market is updated twice a year in case market dynamics change. The impact of the COVID-19 pandemic and the Russia-Ukraine war is considered at a country-specific level.
