Sierra AC763S previously unlocked and now locked again

[Sbloccato]

Is is possibile to unlock again a Sierra 763s, that was previously unlocked with the dongle, just with the codes?

I notice if I reset the unit to factory default, the unlock is gone, but you can still manually type the unlocking number

I do own a DC dongle , but I would like to know if there is a way to retrieve the code once unlocked

Thanks

Sorry, unlock can be done only by software. We do not have unlock codes for these modems.
