I have a 'third batch' X210 from cnmod.cn. I'm struggling to get a Sierra Wireless AirPrime MC7710 working in the second mPCIe slot ("Minipcie 2" in Jackie's post here). I've tried simply installing the card, changing several seemingly relevant BIOS settings, and even taping pins #23, 25, 31, 33 per this article on Techship to disable PCIe -- all to no avail: nothing shows up in my USB device list in Linux.
Does anyone have any other ideas to try? My next route is to purchase a mPCIe to USB adapter, install the modem there, and tell it to ignore the W_DISABLE pin.

T530: i5-3210M - 8GB DDR3 - 15.6" 1600x900 FS
I'm not totally clear on that either. I'm going on the assumption that it will support USB based on others' descriptions of that slot as supporting a 'WWAN CARD'.
In any case, I purchased an mPCIe to USB Adapter Board from Pi Supply (which miraculously made it through Danish customs without incurring the questionably steep handling fee) and can enumerate the card now in a 5.12.9 Linux kernel. Not sure what an 'interface number' means in this context.
