Frequency Band	Band number	Radio Interface	Generation	Status	Notes
1900 MHz	2	GSM/GPRS/EDGE	2G	In Service	Most of this spectrum will/have undergone refarming for HSPA+ and/or LTE services.[74] (More Details See 4G LTE Upgrade)
1700/2100 MHz AWS	4	UMTS/HSPA+ Up to 42Mbit/s	3G/4G[84]	In Service	Has marketed 3G HSPA+ as "4G" since 2011. Covers 230 million+ POPs as of March, 2014. T-Mobile is moving HSPA+ from this band to PCS. Will be refarmed to LTE.[74][85]
1900 MHz PCS	2	UMTS/HSPA+ Up to 42Mbit/s	3G/4G	In Service/Building out	Refarming 3G HSPA+ traffic to this band.[86] Covers 203 million POPs as of Oct, 2013[87]
1700/2100 MHz AWS	4	LTE	4G	In Service/Building out	Together, both bands cover 301 million POPs as of October 27, 2015.[88] PCS LTE is typically deployed in rural areas to reuse GSM antennas. PCS LTE is also being rolled out in urban areas to increase LTE capacity.[89][90][91]
1900 MHz PCS	2	LTE	4G	In Service/Building out
700 MHz Block A	12	LTE	4G	In Service/Building out[75]	Spectrum acquired from Verizon Wireless and other smaller license holders, Band 12 LTE covers almost 175 million POPs as of October 27, 2015.[92][93]
5 GHz	255	LTE	4G	Planned	Unlicensed LTE that was planned to be launched in 2015[88]
