It depends on the Carrier, but we have used multiple carrier sims in this one.

Personally I would recommend staying away from usb modem, they are finicky and we only use them in temporary workaround situations.
My Recommendations:
1) MG21
2) MX67C or something with an internal sim
3) Cradlepoint or other vendor using sim to ethernet
4) USB modem
