Will Smarty support 4G watch esim alongside my current Smarty phone sim?

I've been waiting for Smarty to introduce an esim option which they have finally announced. That's great!

So, I currently use another provider that supports esims, and have a regular sim in my phone and esim for my 4G smart watch.  I can then make and receive calls on my watch using the same number that my phone has and they charge for both sims using one account.

I also have a regular sim with Smarty which I activate and use for when I go abroad for the EU roaming.

My plan is to cancel my other provider and have Smarty supply an esim for my 4G smart watch and activate my current Smarty sim for my phone after porting my mobile number over.

So, my questions is, can I set up my smartwatch with Smarty now to use the same phone number as my phone, allowing for calls and texts on the watch without my phone present as my other provider did?
