I will be installing a pair of MX84s for a customer soon and there is interest on Cellular backup. How do I need to tackle this? Reading the docs, it seems pretty straight forward on getting the MX connected but had some questions as I have obviously never done cellular failover. Do I need to get with the carrier for the modem/SIM or is this something that I need to procure? Just looking for some guidance on how to tackle this since it is new to me. Thanks in advance!
