iPhone 12 Mini, unlocked, Primary line is an eSim with a US carrier, Secondary line is a micro sim with a foreign carrier.
Is it possible to have the Primary line with WiFi calling enabled use the data plan on the secondary line?
For example:
Primary line is my USA number (WiFi calling activated)
Secondary line 2 is a foreign sim with a data plan
Thanks,

Make and receive calls
You can make and receive phone calls with either phone number.
With iOS 13 and later, when you're on a call, if the carrier for your other phone number supports Wi-Fi calling, you can answer incoming calls on your other number. When you're on a call using a line that isn't your designated line for cellular data, you need to turn on Allow Cellular Data Switching to receive calls from your other line. If you ignore the call and you have voicemail set up with your carrier, you’ll get a missed-call notification and the call will go to voicemail. Check with your carrier for Wi-Fi calling availability and find out whether additional fees or data usage applies from your data provider.
If you're on a call and your other line shows No Service, either your carrier doesn't support Wi-Fi calling or you don't have Wi-Fi calling turned on.3 It could also mean Allow Cellular Data Switching is not turned on. When you're on a call, an incoming call on your other phone number will go to voicemail if you set up voicemail with your carrier.4 However, you won't get a missed-call notification from your secondary number. Call Waiting works for incoming calls on the same phone number. To avoid missing an important call, you can turn on call forwarding and forward all calls from one number to the other. Check with your carrier for availability and to find out whether additional fees apply.

Hopefully this helps.
Good Luck!
