Ranking the World’s Largest International Voice Carriers

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.

When Carriers Collaborate

Wanna look at some cool voice data?

The recent expansion of the i3forum's Insights tool has quite a bit of that. I've been itching to talk about it on TeleGeography Explains the Internet. So today we're chatting with the i3forum, a nonprofit industry body focused on "accelerating transformation across the carrier ecosystem."

Put another way: this consortium of carriers routinely collaborates on solving some of the biggest challenges facing their industry. And they have a really innovative way of sharing data among participants, to the benefit of all involved. (Non-members can participate in this data-sharing, too. More of that in our discussion.)
