I am using a Samsung dual-SIM device and would like clarification on the “smart callback” behavior.

Requirement:
When I receive an incoming call on SIM 2, the phone should automatically use SIM 2 for the outgoing callback — instead of the default calling SIM.

Currently, outgoing calls are placed from the default SIM unless I manually select the other SIM.

Kindly clarify:

  1. Is there a built-in setting to automatically use the same SIM as the incoming call for callbacks?
  2. If yes, where is this setting located (One UI version specific guidance appreciated)?
  3. If not available, is this feature supported in any recent One UI versions?

Device Model: S21fe/ SM-G990B2/DS
One UI Version: 8.0
Region: India

Appreciate guidance from Samsung moderators or users who have successfully configured
