If your are equip like me with a EMF meter, then its easy to confirm what your phone is doing when in airplane mode, with normally is nothing. A mobile phone is after all just a computer with a radio modem. It can't do shit without sending out RF. I would recommend something like the 'Cornet ED78S RF Meter' to every technician with the tiniest amount of AU in circulation. The reason I got it was because I have become electro-sensitive, and that's almost a death sentence in the modern city. Those pictures of Stallman sitting on a mountain top and not a mobile phone mast in sight looked very appealing... My phone LG-L80 99£ is GSM only, all else is off, apps downloaded on wired PC and installed via ADB interface. Currently used as book reader for C++11 fourth edition and as Wikipadia offline reader(Kiwix) 12GB on SD card - music/mp4 player and the battery last for a week or more. I feel I'm in control of my phone, don't know if that is justified or not?

What frequencies can an EMF meter pick up? One of my own designs of the past was to hide something in a cable to amplify a signal along 10GHz optionally with a beam hitting it. None of the WiFi security monitors looked for 10GHz. Neither did most cheap, spectrum kits. The dedicated chips in phones with the radios could have extra functionality for other spectrum activated by a trigger, possibly received wireless signal. So, it's a concern to me.

  The one I suggest goes to 6 Ghz I can't imagine that pulsed digital transmission on 10Ghz would not create noise in the lower harmonics bands at all. The meter also have a sound mode where you eg. can hear the ~8-10Khz modulation of the mobile ~700/900/1900/2100Mhz signal. You can clearly hear the difference between different transmission types as DECT phones, Wifi, GSM/LTE, and EM noise in general(PC's/HDMI cables/USB3 HD docks) My central room heater has a small CR battry powered computer (that I had forgot all about) that calculate the bill and transmit the results every 2 minutes on 2.4Ghz it makes a tiny ~0.5 sec pulse on the display/audio, and I thought for an hour that I had a hidden transmitter in my apartment, since turning the mains fuse off had no effect. I had to clear the room of all tech to track down the source, felt a bit stupid when I finally found it. So going down this road has some up's and down's vs staying totally oblivious of ones electromagnetic environment.

    Appreciate the extra info. Might look into getting one. Lmao on the mystery of spying heater.
