AT&T Turbo is an optional add-on service for select AT&T postpaid plans that costs $7 per month per line. It is designed to provide prioritized data and enhanced wireless connectivity for activities requiring high data performance, such as mobile gaming, live streaming, and video calls, especially in congested network areas. Key points about AT&T Turbo:

• It boosts your plan’s premium and hotspot data to "performance data," which means you get higher priority on the network compared to regular users, aiming for better speed and stability.
• It works only on 5G-capable smartphones on eligible plans like Unlimited Premium PL, Unlimited Extra EL, and Unlimited Elite.
• The add-on does not increase your data cap; if you run out of your premium or hotspot data, speeds will be throttled as per your plan’s standard thresholds.
• The Turbo feature can be activated or deactivated monthly per line through your AT&T online account or the myAT&T app.
• The performance improvements may not always be noticeable during peak network congestion.
• It excludes prepaid and entry-level postpaid plans, as well as non-smartphone devices like tablets and hotspots.

The AT&T Turbo brand now appears on phones subscribed to the service as a status bar label saying "AT&T Turbo," indicating the user has this priority data feature enabled. Overall, AT&T Turbo is a way for customers to pay extra to get higher network priority when using data-intensive applications on selected plans and devices, particularly useful in crowded network areas.
