Donald Trump has vowed to deport millions and jail his enemies. To carry out that agenda, his administration will exploit America’s digital surveillance machine. Here are some steps you can take to evade it.
Iirc any cell phone is still capable of dialing 911(or equivalent) even without a sim. So id imagine carrier towers and gps could still find it. You’d basically have to keep the device in a ferriday bag. Which complicates actually using it.
One clarification: carrier towers can still find a phone; GPS is passive; your phone locates itself in relation to the GPS satellites.
Most phones are also broadcasting WiFi MAC IDs and Bluetooth MACs, plus hardware and capability strings over Bluetooth. And then any apps you’ve got loaded may also be calling home with your location unless you have that disabled and rotate your ad ID regularly.
[edit] also worth pointing out that even if you turn a smartphone “off” it still pings the local cell towers with its IMEI regularly. Surprised me the first time I witnessed that.
That is correct. Any cell phone sold in the United States by law is supposed to be able to dial 911 no matter whether they have a SIM card inserted or not and no matter whether they have service on a SIM card or not and also no matter whether one specific carrier in your area has no signal it will use the others instead. You may be a Verizon customer, but if you dial 911 and an AT&T tower picks up the call first, the AT&T network will serve that call instead.
Why does a phone need to be in a ferriday bag when phone does not have a SIM card because it uses web-based VoIP service? The phone only needs an internet connection, like wi-fi, and can’t talk to cell towers. Remove SIM from phone, connect phone to wi-fi to get online to access phone service through the internet, GPS can’t function. If a phone without SIM calls 911, it will go through, but dispatch sees no number, no location, no name.
You have way too much time of doing nothing of significance and fill it with meaningless chatter. Spend more expanding job skills and still listening to so many inexperienced opinions.

any carrier within range can still potentially track you, maybe not with airplane mode but Snowden says don’t trust that
GPS still “works” without any signal, service or net access
AGPS mandate forces 911 calls to reveal your location
For max privacy without going completely analog you’d want a device with NO cellular radio at all

Yeah, but the operator would see an identifiable IMEI.
