Overview

• T-Mobile’s leaked plan says that starting January 1, 2026, LTE or 5G Non‑Standalone activations for business customers will require case-by-case exceptions approved by an internal team.
• Over the next two-plus years, the carrier would re-farm major LTE bands — including 2, 4/66, 12, and 71 — for 5G, with most LTE channels reportedly decommissioned by around 2028.
• The document indicates a single 5 MHz LTE channel would remain for legacy traffic, with LTE maintained in a reduced state until 2035.
• Reports caution that LTE-only and early 5G NSA phones, wearables, and IoT or business equipment could face bottlenecks or degraded performance, while modern 5G SA devices should transition smoothly.
• The coverage is based on a leaked internal roadmap reported by outlets such as The Mobile Report and 9to5Google, with no formal public confirmation from T-Mobile or consumer policy details yet.
