Richard from Privacy International pointed me at these: http://www.amazon.co.uk/dp/B00RRL4XLW It's a faraday cage for you phone. Pop it in and you disappear instantly.

I'd have thought simply switching the phone off would be easier? Much better on your battery life too, if the phone turns the transmit power up to try and reach a base station.

I wouldn't feel safe until the battery is removed (which unfortunately isn't possible on most phones anymore)

The baseband still has access to your battery when your phone is off.

If your phone doesn't have a removable battery, how do you know if it's really off?

Interestingly enough, during last trip to London, my phone (Nexus 5 running Cyanogenmod 12.1) was able to somehow detect something fishy and warned me several times "Network may be monitored by an unknown 3rd party". Among others, I've seen this warning two times out of two when passing by Cheapside/St Martin's corner - next to the St Paul's Cathedral.

At the time I just dismissed this as some tinfoil hat developer adding some nonsensical warnings to the firmware, but in retrospect, after reading this article - this matches perfectly, chances are - phone was indeed detecting Stingrays. Still no idea how it managed to do it.

EDIT: I had no data/IP connection of any kind at and around the time of seeing this, so this is clearly unrelated to TLS interception.

Watched the documentary last night.

Given that these things are cheap, would any fellow Brits be interested in clubbing together and acquiring one and installing it in or around parliament? I'm sure there would be plenty of buyers for the call records of MPS.

Citation needed?

Because the definition of off, for most phones, is exactly that.
