Well after being told one thing by TMobile agents and trying to set up new service this is what I found out about eSIMs: YOU PHYSICALLY HAVE TO HAVE A TMOBILE SIM CARD to make it work. It CANNOT be remotely activated like I was told originally.
I have a factory unlocked N20U and am on VZW. After wasting most of the morning I finally spike with a TMob engineer who said the only way to "unlock" eSIM capabilities is through the software update they just sent out, and to get that particular software update you have to have active TMobile service!
How do you get active TMobile service but by a physical SIM which can then be converted to eSIM.
I only wanted to try their service esp 5G but in order to try 5G you have to sign up for a postpaid plan. I am not about to cancel or port my VZW service until I KNOW TMobile will work for me.
It has been complicated by fact that I live 1.5 hours away from the TMob store so I couldn't just pop in and pick one up...
