Scam Shield

T-Mobile's caller ID and scam-blocking app; the network-side Scam ID and Scam Block keep working without it. It is safe to disable: you lose nothing most people will miss.

What it does

T-Mobile Scam Shield is the app that controls T-Mobile's anti-scam features: Scam ID labels likely scam calls, Scam Block stops them before they ring, and caller ID shows names for unknown numbers. It grew out of T-Mobile's earlier Name ID app and kept that package name. T-Mobile preloads it on many phones and lists it on Google Play; newer T-Mobile help pages also place these controls in the T-Life app.

Also shown as T-Mobile Scam Shield, Name ID.

If you disable it

You lose the app's settings screen and call log. Scam labels come from T-Mobile's network, and Scam Block can be switched on by dialing #662#, so both keep working without the app.

How to disable it

Settings offers Disable for this package on most phones. Open Settings > Apps > Scam Shield > Disable or Uninstall; the exact wording follows the phone's maker.

adb shell pm disable-user --user 0 com.tmobile.services.nameid

adb shell pm enable com.tmobile.services.nameid

The stronger option removes it for your user only; the original copy stays on the phone and a factory reset brings it back. Prefer disabling: it is easier to undo.

adb shell pm uninstall -k --user 0 com.tmobile.services.nameid

adb shell cmd package install-existing com.tmobile.services.nameid

New to ADB? Set it up in about ten minutes.

Data and battery

Checks incoming caller numbers against T-Mobile's scam data and reads your call log to show labeled calls.
