Dual SIM Configuration and Failover

[abc1235]

Hallo,

I have a C1126-8PLTEP ISR router with DUAL SIM capabilities. I would like to configure it such that I when the primary SIM fails, the secondary takes over. What is interesting is that I have created a controller profile for the primary interface but I can't do the same for the secondary cell interface, despite it being available. This is the error message I receive:

R1(config)#controller cellular 0/2/1
Can't find controller Cellular 0/2/1 ^
% Invalid input detected at '^' marker.

The 2 cellular interfaces are shown:

Cellular0/2/0 10.139.223.61 YES IPCP up up
Cellular0/2/1 unassigned YES NVRAM down down

Lastly, why can't I see the controller Cellular 0/2/0 configs in the running config?

controller Cellular 0/2/0
lte modem link-recovery rssi onset-threshold -110
lte modem link-recovery monitor-timer 20
lte modem link-recovery wait-timer 10
lte modem link-recovery debounce-count 6

Thanks in advance.

 - What command completion options do you have when you type : controller cellular ?

Thanks @marce1000. That was actually the problem. An IOS upgrade is required. Thanks again
