Did Verizon’s T-Mobile switcher deficit widen in the later period?
Yes. Across two consecutive transitions, Verizon had 2.1–2.4 outflows to T-Mobile for every reverse inflow. Verizon’s T-Mobile outflow rate rose from 32.4 to 38.8 per 10,000 base customers, while the reverse flow stayed near 18 per 10,000. Verizon’s exchanges with AT&T remained close to even in both periods.

Assumptions & Methodologies
We used recurring carrier payments in YipitData’s U.S. Credit & Debit Panel. Single-homers paid exactly one of Verizon, T-Mobile, or AT&T in the base window. The recent transition used an October–December 2025 base and May–July 2026 outcome; defection required a destination payment and no origin payment. Durability followed 827 Verizon single-homers who had moved to T-Mobile by October–December 2025; 570 remained observable in May–July 2026. Verizon’s merchant label blends wireless and Fios, so wireless movement is a conservative floor. Counts are directional and do not measure market share or promo causality.
