T-Mobile launches carrier audience targeting in Vistar DSP
The new segments use first-party mobile data for digital out-of-home advertising campaigns.
Vistar Media, a provider of technology solutions for out-of-home media and part of 
T-Mobile Advertising Solutions, announced on October 5, 2026, the launch of enhanced audience segments for digital out-of-home activation. The tool is available exclusively through the Vistar demand-side platform.
The feature allows advertisers to use thousands of audience segments powered by T-Mobile's first-party carrier data. The system aggregates consented deterministic signals, such as application ownership, engagement metrics, and location insights, to determine areas where targeted audiences are most likely to spend time during the day.
Vistar then pairs these aggregated scores with available inventory. This process lets advertisers display campaigns on digital screens that best align with consumer movement patterns while preserving privacy standards.
The provenance and the fidelity of our carrier data is a genuine differentiator. It gives us a direct, consented understanding of mobile behaviors that uncover relevant audience interests, engagement patterns, and key areas for activation throughout the day.
