The J-ALERT makes jammer detection and tracking easy, safe and cost effective.When GPS L1 frequency and a cellular band or Lojack is being jammed a bar graph indication of jammer received signal strength (RSSI) from the Jammer is displayed enabling tracking.
Can I tell if my phone is being tracked?
Always, check for an unexpected peak in data usage. Device malfunctioning – If your device has started to malfunction all of a sudden, then chances are that your phone is being monitored.

Is there a cell phone jammer app?
Introduction. Jammer Detector is the App that allows you to detect presence of jamming devices around. In that situation your mobile phone loses the ability to make a phone call.
