Has anyone deployed a solid secondary LTE WAN failover solution with 7th gen SonicWalls, specifically the TZ470?

Looking for feedback on:
-Reliable LTE modem/routers and data plans - I’m on the East side of the US and I use a cheap LTE modem with an AT&T data plan

-Improving failover - I sometimes have to force the failover by disconnecting WAN1 or rebooting the Sonicwall

Primary ISPs vary by site, but all locations have static public IPs on the primary circuit. Considering LTE strictly for backup connectivity.
Would appreciate any deployment lessons learned or hardware recommendations.
