FastGPT from Kagi answers to this question: "Baseband is the firmware that controls the cellular radio functions of an Android device. It is responsible for things like connecting to mobile networks, making phone calls, and sending/receiving SMS messages. [1][2] The baseband firmware resides on the same storage (eMMC) as the Android operating system but runs independently on a separate baseband processor. It communicates with the Android OS through shared memory and AT commands. [3][4] Baseband versions are different from Android build numbers. The baseband version refers specifically to the firmware running the cellular radio hardware. [5] Baseband firmware has been found to contain vulnerabilities that could allow remote command execution if exploited. However, Android devices from reputable manufacturers like Google/Pixel generally receive frequent baseband updates to address such issues.
