Mobile data traffic will grow over fourfold by the end of the decade, with multiple growth drivers

Monetisation is the key objective in 2026 for telcos on APIs (as with other business lines) and their distribution partners, with the implications for go-to-market strategies being different depending on the API and buyer. It is important to quantify the commercial potential and buying likelihood of APIs across different sectors of the economy to accurately orient supply. To that end, GSMA Intelligence has developed the Open Gateway Demand Index, which aggregates a range of metrics to help understand where demand lies and the commercial opportunity for network APIs in each sector.

GSMA Intelligence's Chart of the Month is a visual way of telling an important story in the mobile and broader tech ecosystem. From the shape and size of markets to trends in consumer behaviour, we aim to provide food for thought through informative visuals designed to bring colour and clarity to complex issues facing the industry. This edition looks at which topics telecoms operators focused on at MWC Barcelona 2026.

This report examines operators’ engagement at MWC Barcelona 2026, highlighting their announcements, innovations, strategy updates and messaging, in addition to examining implications for telecoms ecosystem players. We show our findings for 17 major operators across 12 areas of focus, including AI, 5G, B2B, B2C, cloud/edge and emerging tech such as APIs and non-terrestrial networks.
