AT&T’s network performance

Mobile operators’ network performance plays a crucial role in customer retention. In the second quarter, AT&T’s (T) postpaid phone churn rate improved sequentially, falling from 0.84% to 0.82%, suggesting the telecom company’s network is becoming more competitive. This rate reduction looks favorable for AT&T, especially as smaller competitors such as T-Mobile (TMUS) and Sprint (S) strive to attract customers from AT&T and Verizon (VZ).

AT&T has continued to focus on software-defined networking and network function virtualization technologies to enhance its network. At the end of 2017, more than 55% of AT&T’s network functions were virtualized, and the telecom company is on track to meet or exceed its goal of 75% virtualized functions by the end of 2020.


In RootMetrics’ H1 2018 RootScore report, AT&T secured second place in five out of six US network performance categories: overall, data, speed, network, and call performance. AT&T shared the top spot with Verizon in the text performance category. While AT&T’s overall network performance earned a score of 93.0, Sprint’s, T-Mobile’s, and Verizon’s earned scores of 87.4, 87.7, and 94.7, respectively.
