How Do Wholesale Carriers Fit In the Global Traffic Picture?

Broadly speaking, telecom service providers have two ways of connecting traffic to a destination telco.

They can either connect directly with the destination carrier or route traffic to a wholesale carrier that connects to a destination telco.

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 217 billion minutes of traffic in 2024, down 8% from 2023.

Let’s take a moment to dive in a bit and see what's going on.

Wholesale revenues are down 25% from ten years ago. Let’s take a moment to dive in a bit and see what's going on. A few years ago, one could say that traffic to mobile phones in emerging markets had driven international wholesale market growth. No longer.

Wholesale Revenues by Market Type, 2014 and 2024

Wholesale traffic declined at an average rate of 1.5% per year over the past ten years, compared to a -6% CAGR for overall traffic. Wholesale carriers terminated more than two-thirds (71%) of international traffic in 2024, essentially unchanged from the year before.

Traffic to mobile phones in emerging markets has spurred expansion in wholesalers' share of the overall market. In 2024, wholesale carriers terminated over 86% of traffic to South America. In contrast, wholesale carriers terminated only 55% of traffic to western Europe.

Compare the figures for revenue and traffic. It's plain as day that revenues to fixed lines in both advanced and emerging economies has collapsed. At the same time, you'll see that revenues from calls to mobiles in all markets has shrunk slightly over the past ten years, to about $10.1 billion.

Who's carrying this traffic? Take a look at the figure below.

This graph shows a ranking of some of the world’s largest international carriers. The top 8
operators in the figure carried 41% of all global traffic in 2024, about 125 billion minutes. Only one of the eight largest carriers in the world—BTS—terminated more traffic in 2024 than in 2023. Chew on that for a bit.
