T-Mobile completes spectrum swap with Grain Management, acquiring 600MHz assets for 5G network expansion
Type: Partnership · Technology: Telecom · Country: United States · Value: $2.9B · Announced: 2026-08-11
T-Mobile finalized a spectrum swap deal with Grain Management, transferring its 800MHz spectrum in exchange for 600MHz frequencies to bolster its 5G network. The transaction involved T-Mobile offloading 4.85MHz to 14MHz of 800MHz spectrum across 3,224 counties to Grain for $2.9 billion, while acquiring 10MHz of 600MHz spectrum from Grain in 212 counties. The deal, first announced in 2025 and approved by the FCC in July 2026, resolves T-Mobile's long-standing effort to divest the 800MHz spectrum following its 2020 Sprint acquisition. The 600MHz spectrum will enhance T-Mobile's 5G coverage and capacity, supporting its mobile network expansion. Regulatory approval was secured in July 2026, enabling the deal's completion.
