EE is a multi-play UK telecommunications service provider which contemporaneously focuses on mobile and fixed line services. EE was formed in 2010 as a joint venture of Orange and T-Mobile and became the first UK operator to launch 4G on 30 October 2012 through the refarming of 1800MHz. In January 2016 EE was acquired by BT and has since became part of BT's consumer portfolio which operates the three brands BT, EE and Plusnet.
EE Frequencies and Bands
EE operates 2G, 3G, 4G and 5G radio access technologies on a range of bands. 2G uses 1800MHz (Band 3), 3G 2100MHz (Band 1), 4G 800MHz (Band 20), 1800MHz (Band 3), 2100MHz (Band 1), 2600MHz (Band 7) while 5G is on 3500MHz (NR Band 78).

Spectrum Usage Broad Overview
1800MHz 2G+4G is broadly considered to be the network's base layer. Most areas also have 2100MHz 3G. 2100MHz and/or 2600MHz 4G are deployed in highly loaded locations. 800MHz is generally used to improve coverage edges, although it can be the only deployed spectrum in locations of extreme rurality.
EE Carrier Aggregation
EE operates up to seven 4G carriers in each FDD direction, helping support over gigabit 4G capability. Modern devices support five way downlink carrier aggregation, typically meaning maximum bandwidth aggregation is Bands 1+3+3+7+7 for 90MHz spectrum from 15MHz, 20MHz, 20MHz, 20MHz, 15MHz respective carrier bandwidths. In the uplink, uplink aggregation of two carriers is available for a maximum of 40MHz uplink.
EE 4x4 MIMO Configuration
4x4 MIMO is deployed on very busy sites, usually on 1800MHz+2100MHz and increasingly on 2600MHz.
256QAM Downlink, 64QAM Uplink
256QAM downlink and 64QAM uplink are ubiquitous across the network.
Mobile Broadband Network Limited (MBNL)
MBNL is a 50/50 joint venture between EE and 3. While historically it has supported a 3G MORAN (multi-operator radio access network) share, the two operators are increasingly only structure sharing.
IMS: VoLTE/WiFi Calling
EE supports IP Multimedia Subsystem (IMS) services WiFi Calling and Voice over LTE (VoLTE) for pay monthly customers on supported handsets. VoLTE is available on all bands.
For IMS customers calling from and to appropriate devices, Enhanced Voice Services Super Wideband (EVS-SWB) is available. Otherwise Adaptive Multi-Rate narrowband (AMR-NB) at 12.2kbps and Wideband (AMR-WB) at 12.65kbps are the standard codecs depending on the situation
What bands does my device need to work on EE
Answer: For the best network experience, your device needs to support all of the above: 2G 1800MHz (Band 3), 3G 2100MHz (Band 1), 4G 800MHz (Band 20), 1800MHz (Band 3), 2100MHz (Band 1), 2600MHz (Band 7), and 5G 3500MHz alongside appropriate VoLTE and 5G enablement. 1800MHz 2G+4G support is the absolute minimum to be able to use the network in most places however.
