The second value is the DC-HSPA (dual cell HSPA) second cell.  So 1 and 4, 2 and 5, and 3 and 6 face the same direction.

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 CLR band (850MHz, Band 5), but only in one single location: Horry County (including Myrtle Beach), South Carolina. They are also testing CBRS (3500MHz, band 48) as well as E-CLR (850MHz, band 26) in Twin Falls, Idaho. AWS is T-Mobile's primary LTE band.

=== PCS Migration ===
 
T-Mobile is migrating their UMTS PCS spectrum to LTE starting 25 April 2017. For a list of markets, see this support document: https://support.t-mobile.com/docs/DOC-31961
 
== 5G (NR) ==
 
T-Mobile has deployed NR on US 600MHz "Digital Dividend" (Band n71), BRS/EBS (2500MHz, Band n41), AWS (2100MHz, Band n66), PCS (1900MHz, Band n25) as well as on mmWave bands n258 (26 GHz), n260 (39GHz) and n261 (28GHz). They also own spectrum in the n77 (3.7GHz) and n262 (47GHz) bands. n71 is T-Mobile's primary NR band.
