It’s extremely frustrating, I have major OCD and when I log into my account it drives me crazy that it shows a different device compared to what I really have. I know this doesn't impact my services but a mobile carrier should have it right. One thing I think I came to the conclusion and the engineers might need to fix this, is if you purchase an iPhone from Apple “Sim Free” it’ll show a different type of iPhone. I used to have a “sim free” iPhone 11 Pro 256GB Space gray and online it would show that phone but say I have it the midnight green 64GB. I upgraded recently to the Max and it's doing the same thing! I get my phones from apple because with trade-in, and my friend who works for apple gets me a 15% discount it just makes sense for me to do it this way.
Just extremely frustrating that the engineers at T-Mobile can’t get it together to get this problem fixed. We used to have the option to select the device and save it, can we bring that back????
