T-Mobile’s postpaid phone churn rate in Q3 2018

Previously, we looked at T-Mobile’s (TMUS) postpaid customer net additions in the third quarter. Let’s now discuss T-Mobile’s customer retention metric, its churn rate. The company’s postpaid phone churn rate continued to decline YoY (year-over-year) in the third quarter, falling to 1.02% from 1.23%, primarily driven by increased subscriber satisfaction and loyalty thanks to ongoing network quality and customer service improvements. A lower churn rate reduces mobile operators’ customer acquisition costs, expanding their operating margins.
