Can an unlocked phone use T-mo My Account App?

[Windows Central Question]

Hi, I read Steve Penner's great review on the unlocked 735 on T-mobile. I am considering buying one myself, but I wonder if I can install the T-mobile My Account App on an unlocked phone (in general, not just the 735). I use the app here and there, and it's useful to me.

I believe you can, as long as its being used on T-Mobile service.
I flashed my 920 to believe it was the unbranded model from France. Still had the AT&T SIM in it, still has access to those AT&T exclusive apps. Not that they're particularly great, but hey, they're there if i need them.

I used My Account on a Factory Unlocked 1520 when on T-MO.

You will NOT get WiFi calling, however. They reserve that for T-Mo branded phones only.

Yes you can install it. I have the RM-1039 735 using it on T-Mobile. Got it installed and it works. Also on my 830.
