Do you expect your monthly mobile service costs to decrease as network technologies become more efficient?
Global mobile network data traffic exceeded 220 exabytes per month in Q2 2026. This represents a 23 percent increase in traffic compared to the prior year, driven by expanding 5G adoption and data consumption.
Why it matters
Telecom infrastructure costs are largely fixed, meaning that as networks carry higher volumes of data, the cost per gigabyte decreases. This trend allows operators to scale capacity while simultaneously working to stabilize operational energy intensity.
Operators have reduced energy intensity by an average of 15 percent annually since 2019, with Telefonica achieving a 92 percent reduction in energy per unit of traffic since 2015. Deutsche Telekom reported its overall energy intensity declined to 48 kWh per terabyte in 2025.
The players
Reliance Jio
An Indian telecommunications carrier that reported 268 million 5G users as of March 2026 and 241.4 exabytes of data traffic for fiscal year 2026.
Airtel
A global telecommunications services provider that announced a $1 billion investment in its data center subsidiary, Nxtra Data, in March 2026.
Telefonica
A Spanish multinational telecommunications company that has optimized energy use per traffic unit by 92 percent since 2015.
Deutsche Telekom
A German telecommunications company that reported an energy intensity of 48 kWh per terabyte of data transmitted in 2025.
Vodafone
A British telecommunications firm that reported €40.5 billion in revenue for fiscal year 2026 across its 158,000 mobile sites.
The details
Network operators leverage 5G technology—a cellular standard providing higher spectral efficiency—and network automation to manage costs. Software-controlled infrastructure allows carriers to dynamically adjust resources based on actual traffic demand rather than maintaining peak capacity. By distributing fixed infrastructure costs across larger volumes of transmitted data, operators improve the economics of data transmission.
Timeline
2015: Baseline for Telefonica energy consumption reduction calculations.
2019: Baseline for GSMA energy intensity reduction trends.
2025: Operators reported full-year energy intensity and consumption data.
March 2026: Airtel announced a $1 billion investment in Nxtra Data.
Q2 2026: Global mobile data traffic exceeded 220 exabytes per month.
The Tech Race
This development follows the trajectory set by the GSMA energy intensity reduction trend, which tracked a 15 percent annual decline in transmission energy usage between 2019 and 2025. Operators are competing to maintain these efficiency gains while scaling capital investments, with AT&T planning $23 billion to $24 billion in annual expenditures through 2028.
Increased network data capacity and operational efficiencies support the reliability of higher-bandwidth services and 5G connectivity for users globally. These infrastructure investments enable carriers to maintain service quality even as monthly data volume continues to grow across mobile ecosystems.
The takeaway
The falling cost of data transmission per gigabyte is effectively subsidizing the massive surge in global traffic. Watch upcoming capital expenditure disclosures from Verizon and AT&T to see if these efficiency trends persist despite multi-billion dollar network expansion plans.
