Transfer / migrate from the physical sim to eSIM

Hello! I have the physical t-mobile SIM and I want to transfer phone number to my eSIM account / to convert it into eSIM. At the moment I have two tmobile accounts and numbers, is it possible to merge em? (both accounts are prepaid)

I talked to the tech support - and every time I called I had a different information:

• 1st time i was told that in 24hrs everything would be done smoothly (nothing happened so I called again)
• 2d time I was told that T-Mobile doesn't support a feature to transfer the physical sim into the eSIM (when both numbers are tmobile numbers)
• before the first call I tried to reach a text support online - they also didn't resolve any questions and just said that tmobile doesnt fully support eSIM.

What is the truth here? Is it really not possible?
Also an extra eSIM question - if I want to use the same eSIM on a different phone, how to achieve it? Or it is impossible now to perform any kind of eSIM transfers?

Thanks for understanding.
