Cellular support in MX75

[AB1983]

Does MX75 model supports cellular failover and does it support both 4G and 5G?

The only way you want to do cellular failover for models without cellular built-in (like the MX75) is by using an MG gateway with it.

There are 4G and 5G models available.

You can use a 3/4G USB modem, however, your mileage may vary and the support for these is now "best effort" as explained here: https://documentation.meraki.com/MX/Cellular/3G%2F%2F4G_Cellular_Failover_with_USB_Modems

USB modems with MX/Z series devices running firmware MX 18 or newer will be limited to best effort support and will not be receiving any future firmware fixes or improvements. 

As @PhilipDAth, you're better off using an MG or other cellular gateway (Ethernet) plugged into the secondary WAN.
