OnePlus How to set calling SIM card to a contact
OnePlus 3523When using the dual SIM feature on the OnePlus smartphone, we can also assign a SIM card to the stored contacts, which is automatically dialed on each outgoing call without the device asking which number to use.
Note: For contacts that do not have assigned a SIM card, we are asked before the call and we can also set the default SIM for outgoing calls to the phone number directly.
Android 10 | OxygenOS 10.0
