No mobile data during calls

[ZenFone6Talker]

I just found out that there is no mobile data connection while I call someone. So I can't use WhatsApp or Google Maps during a phone call.
Is that a ZenPhone specific setting? Where can I change it.
I have two simcards, one (SIM2) for mobile data only, the other (SIM1) for calls only. Both with 3G and 4G
Thanks 4 help!

No mobile data during calls

I think you are going following.
Data carrier: Sim 1
Call carrier: Sim 2
When you are on call via sim 2. You are not getting data.
This is correct behavior with phones Dual Sim StandBy . When one sim in action other can't be used.
When someone will call you on sim 1 , it behaves like out of coverage area.
If you want call + data at same time, use same sim for both call and data.
Ex: Data carrier / Call carrier: Sim 1

Your Network Carrier must have VoLTE enabled to your device and ofcourse it should be 4G

Enable 4G data instead of 3G data..
