Does this SIMCom card work under OpenBSD with umb(4)? I can see its device IDs were added to umsm(4) in 2018. I'm also looking for a mini PCIe 4G/LTE card to put in an APU4. I'm not sure an M.2 card will fit into the standard case with the added height of the M.2 <-> mini PCIe adapter so I'd prefer to just get a mini PCIe device and avoid the extra adapter. Are there any other umb(4)-compatible devices in a mini PCIe form factor I can look for that will work in Europe? Matt
