How to activate T-mobile Z Fold 4

[userOL37gV51YI]

I took my T-mobile Samsung Galaxy Z Fold 4 that I got from Samsung today. Spent 2 hours on phone with T-mobile and 1.5 hours at store. They told me they could not activate it. Any tips?

I had the same problem too, but I tried like an hour ago and it worked.

Did you just swap sim card or call T-Mobile?

I did it through the website. Since I was a sprint costumer I had to use their website.

Did you just swap sim card or call T-Mobile while swapping sim?

I just swap,no tmobile involved. But,when I pre order ialso select the option for activate without tmobile.So I don't know if it was that.

Like Darkmansec said, the issue is with Tmobile loading the new phone's data until Today (last light). Today is the release date. Thank you all for your help.

use your old sim card from your old phone and it will work
