T-Mobile’s 4G LTE Network To Be Phased Out Gradually By 2028

T-Mobile has clarified its position regarding the future of its 4G LTE network after reports suggested that customers using LTE-only or early 5G Non-Standalone (5G NSA) phones would soon need to upgrade. While initial information indicated a possible early phase-out of 4G services, the company has since confirmed that a full shutdown is still years away.

According to Anushka Bishen, T-Mobile’s Senior Communications Manager, the carrier continues to evaluate its resources but has no immediate plans to discontinue LTE. Bishen emphasized that an LTE shutdown is “years and years” in the future, noting that T-Mobile’s current infrastructure has enough capacity to meet modern data demands. The company will eventually consolidate older technologies like LTE to make way for advanced networks such as 5G Standalone (5G SA) and future wireless innovations.

Originally, internal documents obtained by The Mobile Report suggested that T-Mobile was preparing to begin winding down its LTE network starting in 2026, with a full transition largely complete by 2028. The process would involve reallocating LTE spectrum bands—including 2, 4/66, 12, and 71 MHz—to newer 5G NR bands (n2 and n66), improving network efficiency and 5G performance.

By 2028, LTE services are expected to remain operational only in a minimal capacity—about a single 5 MHz channel—resulting in significantly reduced coverage and capacity. T-Mobile is expected to maintain limited LTE support until 2035, primarily for legacy devices and IoT applications, but with noticeably degraded performance.

The transition will begin gradually, with business customers affected first. Starting January 1, 2026, T-Mobile plans to stop approving most new LTE and 5G NSA activations. Existing LTE contracts will not be extended beyond 2035, signaling a firm commitment to a full 5G ecosystem.

Despite the eventual shutdown, most consumers are unlikely to be affected. Since 2019, nearly all new smartphones have been 5G-compatible, and T-Mobile may offer free or discounted upgrades to customers still using older devices—similar to what it did during its 2G network retirement earlier in 2025.
