com.apple.launchd in Console App

Look in the /Library/LaunchAgents/ or LaunchDaemons folders for the .plist file related to the T-Mobile software and delete it. Then reboot.

Not much. The reference to Huawei appeared in the other messages. Perhaps there's a Launchd .plist still lingering somewhere. Download Easy Find - VersionTracker or MacUpdate - and use it to search the drive for remnants of the software. It searches where Spotlight doesn't and is easier to use to search for invisible files. I would also check in the /System/Library/Extensions/ folder for a .kext driver that may still be there.

Launchd is used to execute programs, and can be "scripted" via the com.whateve.plist files located in the LaunchAgents and LaunchDaemons folders in both the /Library/ and /Home/Library/ folders. I suppose it's possible the software installed its script as a startup item in the /Library/StartupItems/ folder.

if you have managed to delete all the relevant items but have not restarted the computer, then the offending daemon is still running, and won't cease until you kill the process or restart the computer.

I'm pretty much out of ideas, otherwise.
