A good start is:

You're pretty safe with Sierra MC7700, MC7710, MC7750 (PCI-E minicards)
and the EM series (M.2/NGFF minicards).  Other known working ones are
Novatel E3xx devices and the various Ericsson ones (5521, 5321, 3607,
though they are EOL and don't support LTE).  First make sure that the
device supports the bands your provider uses.
