Dual SIMs on an iPhone SE

Hey there brye224,

Welcome to Apple Support Communities. You should be able to accomplish this by using the nano SIM for the Wi-Fi only calls, and the eSIM for cellular only calls. Of course, this is depends on whether your wireless carrier supports both eSIM and Wi-Fi calling. The steps to set up Wi-Fi calling are listed here: Make a call with Wi-Fi Calling - Apple Support

"Add a device to use it with Wi-Fi calling

1. Check that the device that you want to add has the latest version of software.
2. On your iPhone, go to Settings > Phone > Wi-Fi Calling.
3. Turn on Add Wi-Fi Calling For Other Devices.
4. Go back to the previous screen, then tap Calls on Other Devices.
5. Turn on Allow Calls on Other Devices if it's not on. A list of your eligible devices appears under Allow Calls On.
6. Turn on each device that you want to use with Wi-Fi Calling.

Next, make sure that your other devices will accept calls from your iPhone:

• On your iPad, go to Settings > FaceTime. Then turn on Calls from iPhone.
• On your Mac, open the FaceTime app and choose FaceTime > Preferences. Then turn on Calls from iPhone."

And, the guidance for setting up an eSIM is found in this Apple Support article:
