I’m having issues get the MS2372h-510 modem to work. When I plug it in to the raspberry pi the light just flashes purple.

Have you tried to set up your modem using the usb_modeswitch command? Are there any error messages?
This is the Linux command that allows switching the mode of USB-devices: from storage to modem. It’s the simplest way to set up a 3G USB modem on Raspbian.
