The datasheet of STM32WL33KB states that the frequency bands 159-185 MHz, 413-479 MHz, 826-958 MHz are supported.

However, the website mentions that "For greater flexibility, it supports wide frequency bands from 100 MHz – 2.4 GHz".

Can I get some clarification as to whether 2.4 GHz is supported or not?

Hello @leahjoseph and welcome to the ST Community :smiling_face_with_smiling_eyes:

The 2.4GHz is supported only for on the Wake-up radio receiver and not for the Ultra-low power Sub-1GHz RX/TX transceiver. The STM32WL33 include two separated Radio modules:
