Dual eSIM on iPhone 14

I'd like to confirm that it IS definitely possible to have dual eSIM phone numbers activated on a single device with T-Mobile.  I currently have this with an iPhone 14 Pro Max.  The ease of doing this may depend on whether these are new phone numbers, are ported over numbers from another provider and just what T-Mobile support staff you end up talking to.  If the following is similar to your situation then this may work for you as well.  Nobody at T-Mobile was ultimately able to help me do this after 7 hours of multiple elevations of telephone assistance with T-Mobile and Apple along with two trips to local T-Mobile stores.

I was porting over two numbers from two separate phones from another provider onto a single T-Mobile iPhone 14 Pro Max..  While both numbers ported over easily to T-Mobile service only one was able to be transferred onto the iPhone.  When trying to activate the second eSIM, the second number stubbornly always came up with an error message stating that the number wasn't eligible for porting to T-Mobile (even though it already was).  It's just the phone wouldn't accept it. 

To end what was a long painful story, since I still had my old phone which was on IOS 16 and had a physical SIM slot, I asked the T-Mobile store to activate a physical SIM card with that second number for use in the old phone.  Once the old phone became activated with the second number that I wanted to transfer (a 10 minute process), I was able to put the old and new phones side-by-side to transfer and activate the second eSIM in the new phone without any problems.  In theory, you should also be able to do this using a QR code but support seemed fixated on the path of direct activation.

Note that the T-Mobile staff was always patient and polite but just didn't have the answers for what I assumed would be a very common request.  The phone works great now with both numbers.

Hope this work around might be useful for some.

I was hoping someone tried this. I just moved a second line to an iPhone 14 using this method and it was seamless. I am going to try it with my girlfriends Galaxy S9. Take that sim put it in an iPhone running iOS 16 and hope it works. But it sounds like T-Mobile is stumped at adding a second different line to a phone where the EID is already associated with a line. If they fix that these number transfers should be much easier
