Fellow humans, there are alternatives to being tracked via cell phone! Your neck need not be under anyone's boot! You don't even need to give up any functionality:
Data service:
The simplest thing is to buy a prepaid SIM and top it off with cash. The lovely people over at /r/nocontract maintain a big spreadsheet so you can filter by various properties of the available contracts.
Another way to go is to pay for a postpaid plan with a virtual credit card (e.g., privacy.com). It won't be linked to your name at the telco, but of course privacy.com knows who you are.
Yet a third way to go, which is nascent, is buy an eSIM with crypto.
All these methods make you /pseudo/nymous, but obviously you're still identifiable by subscriber number and possibly IMEI, to put aside correlational things like your traffic profile. You can help this problem by routing everything through a VPN. Then you're pseudonymous but the cell carrier knows nothing about you other than that you use a VPN. Pay for the VPN with crypto. Of course now the VPN provider knows your traffic, but you're much more anonymous to them than you are to a telco. You make your choices. Defense in depth. Etc.
OS:
CalyxOS: https://calyxos.org/ Privacy-respecting Android distribution that replaces Google spyware with MicroG, so you can have your cake and eat it too. Most everything will work as you're used to, but it does still talk to Google to make that happen.
GrapheneOS: https://grapheneos.org/ Very much like Calyx, but extra-hardened and with no MicroG. No involvement with Google at all by default. You can use the work profile thinger in Android to set up an environment where you can run unprivileged Play services + whatever crapware you need that requires them.
LineageOS: https://lineageos.org/ The successor to CyanogenMod, will work with many different phones. More privacy and control than stock Android.
There are also many others: Sailfish, Replicant, e
Hardware:
CalyxOS and GrapheneOS run best on Pixel 3, 3a, 3XL, 4, 4a, 4XL, 5, 6, 6a. The path of least resistance is to get one of these phones and run CalyxOS (if there is an app you need to use that needs Google services like Firebase Cloud Messaging...note that many that can use FCM will run fine without), otherwise run GrapheneOS.
You can also buy a Librem 5 https://puri.sm/products/librem-5/ If privacy and security and hacking are really important to you.
