I have an s22 Ultra and a Pixel 7.
I have figured out how to get more than one T-mobile eSIM on the S22 - by using the “Transfer eSIM from another device” choice on the “Add eSIM” menu. Using this method the system doesn’t care if you already have one or more a T-mobile eSIMs on the phone, it will transfer the eSIM.
However, the Pixel 7 has no such transfer menu, it just has the generic QR code method. However, that method will not install a T-mobile eSIM on the phone, T-mobile blocks this transfer and you get an error.
Anyone out there able to install more than one T-mobile eSIM on a Pixel? If so, how did you do it?
