We have deployed a handful of ASR 920 routers and are collecting
Netflow from them with NFsen. It seems to work okay apart from the
timestamps in the Netflow records. The are all just epoch start.

Thank you for the input. So it seems there is an ISR1000 router with
dual modems, the C1109-4PLTE2P Bjørn mentions. I'll look into that.
I can see from the configuration guides that the other models that
claim "Dual SIM Support" can only do failover. Expected failover time
is in minutes.
