Ranking the World’s Largest International Voice Carriers


By Patrick ChristianJan 11, 2024


Many retail service providers, such as mobile operators, MVNOs, and cable broadband providers, rely heavily on wholesale carriers to transport and terminate their customers’ international calls.

Wholesale carriers terminated approximately 257 billion minutes of traffic in 2022, down 5% from 2021. Wholesale traffic declined at an average rate of 1% per year over the past ten years, compared to a -2% CAGR for overall traffic. Wholesale carriers terminated nearly three-fourths (72%) of international traffic in 2022, up from 70% the year before.

Traffic to mobile phones in emerging markets has spurred expansion in wholesalers' share of the overall market. In 2022, wholesale carriers terminated over 87% of traffic to Sub-Saharan Africa and South America. In contrast, wholesale carriers terminated only 56% of traffic to Western Europe.

Wholesale revenues have changed only marginally from ten years ago. But let’s take a moment to look under the hood.

Over the past decade, traffic to mobile phones in emerging markets has driven international wholesale market growth.

Notes: Advanced markets are defined as those of the upper 30th percentile of countries as ranked by GDP per capita in 2022. Emerging markets are those of countries in the lower 70th percentile.

In the figures above, you'll notice that revenues from calls to mobiles in emerging markets (the yellow segments) noticeably bulged from $9.7 billion in 2012 to $10.7 billion in 2022.

As a portion of overall wholesale carrier revenues, calls to advanced economies shrank, as did revenues from calls to fixed lines in emerging markets.

Who's carrying all this traffic?

The next figure shows a ranking of some of the world’s largest international carriers.

Notes: Pre-2013 data for Vodafone, which reflect the combined traffic of Vodafone and the former Cable & Wireless Communications, are not available. In 2021 Vodafone Idea India and Vodafone Australia traffic is no longer reported under Vodafone structure due to ownership changes in 2020. Source: TeleGeography, © 2023 TeleGeography

The top nine operators in the figure carried nearly half of all global traffic in 2022, about 178 billion minutes.

Among the nine largest carriers in the world, only Deutsche Telecom terminated more traffic in 2022 than in 2021.
