how to transfer esim to new device

magenta7858378

    i have already activated my esim with the app on iphone xs. now i have a new xr and want to use the esim there instead. but i can not login tothe app on the new device as it is only for new lines and no download esim function,... on my t-mobile either?

     

    any idea how we can transfer the esim to a new device as we do with physical sims?
