how long does it take for my phone to show unlock status?

how long does it take for my phone to show unlock status? I recently paid off my iphone through t-mobile. I am traveling outside of the country for military duty and need to get a local e-sim card. The T-mobile account shows the phone is unlocked, the t-mobile rep tells me it's unlocked, but when I go to my settings, it still shows it's locked. its been a couple days now, and I really need to get service in this new country.
