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.
That's not a great solution if I want people to be able to call me.

The fact the Government is using it as an identifier likely means they can argue legally you are attempting to change the identifier. Technically correct for technical discussions is not the same as contextually correct in a court room.
IMSI is not a mobile phone identifier, it literally means International Mobile Subscriber Identity and is provisioned in the SIM card. You will change your IMSI by simply changing the SIM card.
If you use pre-paid sim cards then those usually have thin provisioning of IMSI numbers they network buys a certain amount and activates them when the SIM card is activated and deactivates them once the SIM card has been inactive or not been topped off for a certain period of time (usually around 90 days).
When some one has your IMSI they can tie it directly to your personal details, phone number and various other details if they have sufficient access to the global cell system they can also get your location and what tower you are connected to. Historical log data will give them any tower you've been connected too from the first tower during the initial activation and provisioning to the last tower you've been connected too. Depending on the network and device most phones also send out nice diagnostic information about other towers and networks they see all the time regardless of what tower they are connected too at the time that with a given IMSI number will allow some one to triangulate the position of the device to under 10M in most urban areas if some one knows your IMSI they can pretty much pin point what room you are in at your house (give your house have several rooms pointing at different directions ;)).

Well, as they're officially not used at all in the UK, there's been no need to create any legislation around them, so while this could be an offence under the communications act, you could argue (probably unsuccessfully) that you're actually providing a service to customers by taking their data to protect them from themselves, as they may be terrorists and not yet know it.
It's almost certainly an offence under RIPA.

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 is lying to you about being switched off, then it's already compromised (and you're probably under some highly targeted surveillance already). If I had any evidence this had happened to me, I'd get rid of the phone instead of trusting it under any circumstances. For the example of a protest march, if you're a participant or even a bystander walking home wanting to avoid being caught up in a surveillance…
Burner phones bought in cash from one of the little independent shops we have all over (here in the UK anyway) with pre-paid sims - not a new idea I saw it cropping up in fiction 20 or more years ago but still effective, used for a day or two and then dumped.
Isn't it tragic that the way you have to protect yourself from the state when organising a legal protest is pretty much the same way you would do it if you where a drug dealer or a terrorist (at least a reasonably smart one).
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 a…
Is it completely legal to warn users of suspicious network activity like this? If for example Apple built detection into iOS and gave all users a warning that could do a lot for raising awareness and maybe some support for change. "The network you are using is likely being surveilled. Your identity, online activity, and phone calls may be monitored by government or criminal equipment"
It seems to me that if you really want people to slow down near the elementary school (as opposed to just issuing tickets and collecting fines), this is EXACTLY what you want to have happen. If you put a cop there, and people warn others of it so they all slow down... mission accomplished!
By analogy, if you've got a target very valuable to the enemy (maybe a stadium for a high-profile sporting event), having phones alert users that they're being monitored might help to ensure that nobody tries anything during the event.

Frequently on my town's facebook page, somebody will post "speed trap near the elementary school, better slow down there", and people jump all over the poster about helping people get away with speeding. It seems to me that if you really want people to slow down near the elementary school (as opposed to just issuing tickets and collecting fines), this is EXACTLY what you want to have happen. If you put a cop there, a…
To be really effective, it would be seem specific and personal: text messages that say things like "We can see you. We know what you're up to." Stuff like that.

Any number of phones over the years have/had functionality separate from the main OS (and in some cases backed with a small secondary battery) to trigger the phone to wake up to play alarms etc.. Given that the baseband code is totally closed and has total control over the phone, if the physical capability is there all it takes is a suitable vulnerability. I would not trust that any modern smartphone is fully off wit…
Are you sure they don't have a backup battery or similar that can continue broadcasting your location after you pull the battery. That would be an ideal countermeasure as pulling the battery would be a great indication you may be about to do something "naughty" and you'd likely do such things shortly after too ...

That is not enough. Use a faraday cage.
Modern phones have two batteries [0].
