SARBACKOFF/SARSTATEDFL problems

Hi, I’m trying to set a backoff but when I apply the state the modem have a hard time reconnecting even when I set back the state to 0.

The modem will eventually connect back after some time (1 hour or more)(?).
All commands returns OK. The provider does not use the band.

AT!OPENLOCK?
AT!ENTERCND=“A710”

AT!SARBACKOFF=2,5,8,92
AT!SARSTATEDFLT=8
AT!RESET

Modem will not reconnect.

AT!SARBACKOFF=2,5,8,0
AT!SARSTATEDFLT=0
AT!RESET

Modem will not reconnect (or will reconnect after a while/after reboot, not sure…)
