Android deliberately scans for open WiFi and Bluetooth endpoints even when these functions are disabled by the user. Google knows exactly where you and what you’re doing, and LE can just buy your data from them a week later and prosecute you.

If you remove the SIM card and don’t connect to any hotspot ( obviously ), then your phone is just a camera

That is not true and it is a dangerous assumption for someone planning to antagonize law enforcement.

A phone that is powered on, even with no SIM or WiFi, would still be able to track your location. It still has GPS-GLONASS-Galileo, it still has a cell radio, it still has Bluetooth, etc. How do you think a phone can let you still call 911 even with no SIM?

This article offers a high level explanation:

GPS tracking without a SIM card offers a resilient and dependable solution for location-based tracking and management.

Unless you leave it home or physically remove the battery, your phone can still be used to track you (given the resources that a state can bring to bear.) If you aim to misbehave, do not trust your phone.

Your SIM card just grants you access to any particular network, your phone can still be tracked off of its serial number or IMEI as other towers in the area, regardless of whether or not they are your carrier, will log the devices that pinged the tower.
This MIGHT be ok with a burner phone if you paid with cash, but they could still pull data from in store security systems of the purchase by tracking the phone to the point of sale with its IME, if they were sufficiently motivated.
It might work, But it’s a gamble I’m not willing to take.
