7.15.1î™–î™–î™–î™–Description
Sets the supported 4G LTE bands for different Radio Access Technologies (RATs). The bands supported are
set by a bitmask where each bit in an 8 byte integer corresponds to a 4G LTE band.
Reboot the module (+CFUN=15) in order to make the setting effective.
u-blox cellular modules are certified according to all the capabilities and options stated in the Protocol
Implementation Conformance Statement document (PICS) of the module. The PICS, according to 3GPP
TS 51.010-2 [84], 3GPP TS 34.121-2 [85], 3GPP TS 36.521-2 [115] and 3GPP TS 36.523-2 [116], is a statement
of the implemented and supported capabilities and options of a device. If the user changes the command
settings during the certification process, the PICS of the application device integrating a u-blox cellular
module must be changed accordingly.

• Bit 2: band 3
• Bit 3: band 4
• ..
• ..
• Bit 63: band 64
<bitmask2> Integer Indicated the bandmask for 4G LTE bands 65 through 128. Each bit enables/disables
a band.
• Bit 0: band 65
• Bit 1: band 66
• Bit 2: band 67
• Bit 3: band 68
• ..
• ..
• Bit 63: band 128
