I just purchase a MAX-BR1-SLIM-LTE-US-T and the WAN failover priorities work perfectly between WAN, WiFi-WAN, and Cellular in SIM Slot A. However, when I disable WAN and WiFi-WAN, for testing purposes, the Cellular WAN does not failover from SIM Slot A to SIM Slot B when I lose service from my provider (my Sprint connection seems to only last 4-5 minutes where I am currently located but I suspect that’s just a covergae area issue). Both of my SIM slots show that a SIM is detected. I currently have a Sprint SIM in A and a T-Mobile SIM in B. I have tried them reversed and still the same issue.
I’m currently running firmware version 6.2.2 build 1790 (which came on the router out of the box). I’ve also tried using the latest version, 6.3.1 build 2023 but that version will not recognize my Sprint SIM. Additionally, the only way I’ve been able to get the router to recognize my Sprint SIM in Slot A is to set the Network Selection to Manual and then scan and select Sprint. With T-Mobile in Slot A, I can leave the Network Selection set to Auto. I’ve tried setting SIM Card to B Only and then inserted both the Sprint and T-Mobile SIMs in the slot with neither being able to connect to the cellular provider.
Below are my current cellular settings. I have configured the email settings to warn me when I come close to reaching my monthly data cap (I’ve tried between 1-10MB) but I have yet to receive an email. However, I do receive them when the WAN status changes so I know my notification setup is correct.
Any ideas as to why SIM A is not failing over to B or why I am not getting the email messages when I reach 75% and 95% of my configured Monthly Allowance? Any and all help is appreciated.
