Good morning,
In Android check call settings > more settings > voice call > transfer:
- always transfer
- transfer if busy
- transfer if no response
- transfer if unreachable
etc.
Otherwise, check directly with the mobile operator, a deviation could be active…
Best regards

On the Samsung, in the “Phone” application, (as if you were dialing a number)
Type:
##62# and make a call…
code 62 takes care of diversions if the phone is turned off or in an unreachable area.
it may be that it is the “if no response” diversion (after a certain time) that is programmed. In this case to delete it, type:
##61# and make a call…
