Welcome to Android Central!
Try this: Open Settings->Apps->Smiths (or whatever they call their app). There should be two buttons - one labeled "Force Stop" and the other labeled "Disable" or "Uninstall." If that second button says "Disable," then it seems like the app may be built into the phone's system software (and you can thank your mobile carrier for forcing it on you).
