T-Mobile uses AWS (1700/2100 MHz) and PCS (1900MHz) spectrum for 3G. In some areas, T-Mobile has migrated HSPA from AWS to PCS to allow more bandwidth for AWS LTE.

T-Mobile has deployed LTE on AWS (1700/2100 MHz, Band 4), PCS (1900MHz, Band 2), and 700 MHz A block (Band 12). AWS is T-Mobile's primary LTE band. It was used exclusively during T-Mobile's initial LTE deployment in 2013. PCS spectrum began deployment in 2014 as a cost-saving measure to allow rural 2G-only sites to be upgraded without requiring new antenna panels. Markets where T-Mobile holds limited AWS spectrum, such as Cincinnati, also use LTE on PCS spectrum. 700 MHz is in the early stages of deployment and will added to existing sites to improve building penetration and coverage area.
T-Mobile has deployed LTE on AWS (1700/2100 MHz, Band 4/66), PCS (1900MHz, Band 2/25), 700 MHz A block (Band 12), BRS/EBS (2500MHz, Band 41) and US 600MHz "Digital Dividend" (Band 71). T-Mobile also has deployed LTE on the 850MHz cellular band (Band 5), but only in one single location: Horry County (including Myrtle Beach), South Carolina. They are also testing CBRS (3500MHz, band 48). AWS is T-Mobile's primary LTE band. It was used exclusively during T-Mobile's initial LTE deployment in 2013. PCS spectrum began deployment in 2014 as a cost-saving measure to allow rural 2G-only sites to be upgraded without requiring new antenna panels. Markets where T-Mobile holds limited AWS spectrum, such as Cincinnati, also use LTE on PCS spectrum. 600 MHz is in the early stages of deployment and will added to existing sites to improve building penetration and coverage area.

Band 12 has been reported on sectors 4-6 and sectors 21-23. It is unclear what will become the preferred layout.
=== PCS Migration ===
Band 2 on some towers have been migrated from sectors 1-3 or 7-9 to sectors 11-13.
Towers with band 12 on sectors 4-6 are  being migrated to 21-23 on some towers.
