Fallback to preferred SIM behavior

[whillegass]

What is the precise behavior of this setting?

Lets say the device has been on the fallback sim for 10 minutes.
When the device switches to the primary sim it realizes that it still has terrible connection with the primary. Does it then switch back to the secondary for ten more minutes?

What does idle setting above refer to? The device doesn’t process any traffic for three seconds?

Thanks!

Yes. But only if it fails to get a healthy connection on the primary SIM. It is not measuring quality just availability.

Yes exactly.

So the 10min setting here forces the modem to try the primary connection - even if that causes a connection outage for the users. Without that setting, it will only try the primary SIM if the modem is not processing user traffic.
