USB 4G LTE - backup for CCR1009-7G-1C-1S

Dear Sirs,
we need a backup internet provider, I’m using a Lenovo K6 with USB thetering and it see a LTE interface, added DHCP client and it works fine.
Now we need a stable alternative that would run 24x7, are these USB LTE modem working properly with Router OS 6.40.1?

Verizon MiFi® 4G LTE Global USB Modem U620L
tp-link M7300 - 4G LTE-ADVANCED MOBILE WI-FI
D-Link DWM-222

Please let us know, thanks, BR

Considering using something like this or this to avoid USB all together.
