That's certainly one thing to try. However, your phone and T-Mobile may cache assigned IPs so that it doesn't change them out for a certain period of time.
By the way, it wouldn't be 'log out', it would be disconnect from cell data service (i.e. go airplane mode) and reconnect.
The point is that sometimes it is out of your hands and out of T-Mobile's hands and isn't a malicious action, just a bad situation due to having $h1thead hackers out there in the world.
