Pop that sim In Your phone and I'm not sure anyone could track you.

There’s also the IMEI (International Mobility Equipment Identity). If the SIM is kind of like your IP address the IMEI is like your MAC address, a unique hardware identification number. The wireless companies track and use this too:

GSM networks use the IMEI number to identify valid devices, and can stop a stolen phone from accessing the network. For example, if a mobile phone is stolen, the owner can have their network provider use the IMEI number to blacklist the phone. This renders the phone useless on that network and sometimes other networks, even if the thief changes the phone's subscriber identity module (SIM).

In the scenario the OP provided he’s trying to avoid government level tracking. They no doubt would know his phone’s IMEI as well.
