Telecom postpaid phone churn measures the rate at which postpaid phone customers disconnect service under the carrier's stated methodology.

It is a wireless customer-retention measure, not a subscriber-growth rate.

Lower churn means fewer customers must be replaced

AT&T reported second-quarter 2026 postpaid phone churn of 0.86%.

Verizon reported wireless retail postpaid phone churn of 0.92%.

Small changes matter because the percentages apply to tens of millions of phone connections.

The calculation is usually monthly

AT&T defines monthly churn as customer cancellations during a month divided by subscribers at the beginning of that month, with the quarterly rate equal to the average monthly churn rate.

Investors should still preserve each carrier's exact reporting scope when comparing churn.

Churn can improve for different reasons

Network quality, pricing, customer service, device financing, promotions, and switching friction can all affect retention.

Low churn is useful, but it should be read together with net additions and acquisition spending.

Primary-source examples

Telecom postpaid phone churn is most useful as a wireless customer-retention measure. Pair it with subscriber count, net additions, pricing, promotions, and customer-acquisition costs.

Part of the Telecom Wireless & Broadband Operating Model

Connect postpaid phone scale, growth, churn, broadband net additions, installed fiber and fixed-wireless bases, and prepaid phone scale, growth, and churn to understand telecom customer-base economics.

How the model fits together
  • Postpaid phone base, growth, and retention: Postpaid phone subscribers show the recurring phone base, net additions show whether it is expanding or contracting, and postpaid phone churn shows the rate at which customers leave. Issuer definitions remain specific to each carrier's retail population.
  • Broadband growth and access mix: Broadband net additions show total high-speed connectivity growth, while fiber and fixed-wireless net additions decompose the access technologies driving that growth. AT&T and Verizon use related but not identical internet and broadband labels.
  • Installed broadband base and prepaid dynamics: Broadband, fiber, and fixed-wireless connections show the installed access base behind net additions. Prepaid phone subscribers, net additions, and churn add a distinct lower-commitment wireless customer layer whose acquisition and retention economics differ from postpaid.
