Overview

• Multiple outlets cite a leaked T-Mobile document indicating most LTE spectrum will be re-farmed to 5G Standalone over the next two-plus years.
• The leak says LTE or 5G Non‑Standalone activations for business customers will require exceptions starting January 1, 2026.
• T-Mobile would keep a single 5 MHz LTE channel as a degraded legacy fallback until roughly 2035, according to the document.
• Reports say LTE‑only and early 5G NSA devices—such as some flip phones, wearables and IoT hardware—could face degraded performance or require upgrades, while recent 5G SA‑capable phones should continue to work.
• T-Mobile has not issued full consumer-facing details, and analysts note the timeline could shift as customer migration and real‑world deployment progress.
