Is it a good enough solution for IMEI tracking to use an alternative device to provide a hotspot connection?
This approach appears to protect any new device that hasn’t inserted a SIM card from being identified.
But I’m not sure how much information is carried to the second device by using hotspot.
Is this a good solution so far? Should I try to spoof IMEI?
The main goal here is to keep my device’s IMEI number private, so that it appears to the service provider as if my phone has never used cellular data. By hiding the IMEI, the provider won’t be able to associate the device with me when I use it solely on public Wi-Fi such as in a café, or be able to track me with IMEI if my IMEI number is leaked by some service or app that I accidentally used. They might see that a new device is connected, but they won’t be able to identify that it belongs to me.
Now that I think of it twice I think you got a point Solely connecting to WIFI doesn’t seem to leak my IMEI number. But I’m not sure what else will except for using SIMs.
I guess I just don’t like the idea that a persistent number could be used to identify me.
Though I’m still curious about:
I think you’re a little confused. Connecting to Public Wifi (or any wifi), will not reveal IMEI, it does reveal your Wifi MAC Address, and if you have Bluetooth on, it will reveal your Bluetooth MAC Address, but will not reveal your IMEI (unless you have malware on your phone).
In modern smartphones, including iOS, Android, and especially GrapheneOS, Wifi MAC addresses are spoofed by default, generating a random MAC address for each Wifi network. You can even go to Developer settings of Android to enable randomization for each different session of the same wifi network (or you can “forget” the network and reconnect and, from my testing, it would immediately change the MAC address for that network).
Although, if you have iOS or Google’s Android, you can’t be sure if the companies themselves are tracking you, but but a privacy Android ROM (like GrapheneOS) with Wifi MAC randomization enabled should be very safe.
Keep Airplane mode on so it stops connecting to cell towers.
Your device name and Wifi MAC address is revealed, so change the default “Google Pixel” to something else to hide the fact that it’s a Google Pixel. But, some wifi access points can detect your device model anyways. My Xfinity gateway will show my Phone’s name and what model of phone I have. So I’ll just assume that: Device Name, Device Model, and MAC (which is randomized) is known. Shouldn’t be that much of a privacy risk unless Google Pixels aren’t popular in your area. If there are a lot of Google Pixels around, they can’t prove it was your Google Pixel.
thank you for the clarification!
changed my device name!
I cannot find any reliable source that says personal hotspot can see the device model connecting to it, would be really great if someone could clarify this here.
I believe this is true as there is browser plugin for spoofing device model
