Can I forward calls and text messages between my Fig Phone and iPhone?

You can forward your calls from going from your Fig Phone to the smartphone.

Yes, you can forward them and you can turn off your forwarding when you don't want to forward them.

No, because the iPhone is a digital SIM and the Fig Phone is a physical SIM. So there's no way to swap it out?

Unless you had an iPhone that had a physical SIM card.

I appreciate your help. Thank you.
