BR1 SIM failover fine tuning

Hi, we use BR1s with two SIMs. Sometimes the main SIM behaves in ways that it appears to be active but no navigation…that way the backup SIM never enters. Our customer would like to have the secondary SIM to act when the main:

  • Lowers speed
  • Increases latency (that seems to work now with a new feature)
  • allowance ends (also with a feature in the bandwidth allowance )

Any advise is appreciated, thanks
