lsusb for an M.2 module will do nothing. And lspci I suspect will do
nothing either, it is not the PCI bus.

I tried on a computer here, and the m.2 disk is not detected that way.

Best hope is google: "how detect M.2 modules in Linux?"

It depends on the device. M.2 can provide PCIe (lspci detects also
PCIe and AGP), SATA or USB.

I would expect the majority of WWAN modules are USB, even in M.2 form
factor. lsusb should show it.

M.2 storage can be either PCIe (would show in lspci as an NVMe device) or
SATA (would not, but would show at boot in dmesg).

I've never used one. A quick search leads to
https://www.kernel.org/doc/html/latest/networking/device_drivers/wwan/index.html

Figure out which kernel module is needed and try loading it with modprobe.
See if that shows anything in the journal.

True, my module is USB and can be detected by lsusb.

The WWAN module is for a wireless wide area network device, not a storage device.

WWAN is similar to a wireless internet device but instead of connecting to a
router it connects to a cellular network like cell phones do.

True, and therefore it can't use SATA via M.2, but it can use PCIe or
USB.

Also, to be usable, it will not only require support in the kernel, but
also configuration frome userspace applications where you might need to
set things like network operator and access point names. Example of some
WWAN documentation:

https://www.kernel.org/doc/html/latest/networking/device_drivers/wwan/
t7xx.html
