Operator Popups,
Closed Before You Tap.

Operator popups can subscribe you with one mis-tap. USSD Guard closes them before you even see them, and logs every attempt.

Features

Popups Closed Before You See Them

Every feature below is in the app today.

Blocks Popups Automatically

SIM Toolkit and USSD dialogs are closed with Back the instant they appear — even over the lock screen, even with the app closed.

Context That Protects You

Your own balance checks and SIM menus you open yourself are never touched. Only what you did not ask for gets dismissed.

Every Popup Logged

The full text, the time, and the guard's decision, kept as an audit trail on your phone.

Never Presses OK

On a subscription popup, OK is the trap. By design, the guard sends Back — or the popup’s own Cancel when Back does nothing. It cannot consent on your behalf.

Survives Battery Savers

A heartbeat watches the watcher: if your phone quietly kills protection, you get a clear warning and a one-tap fix.

Your Data Stays Yours

Detection is 100% on-device. No SMS access, no ads, no tracking — only purchase processing contacts Google Play.

How It Works

Protected in Three Steps

Turn it on once; it watches in the background.

  1. Turn On Protection

    USSD Guard explains its accessibility service, then asks Android to turn it on.

  2. Popups Close Themselves

    Unrequested SIM Toolkit and USSD popups are closed with Back, or their own Cancel.

  3. Check the Log

    Every popup is kept with its text, its time and the decision taken.
