I’ve gotten prepaid sims for things but obviously that’s not really a feasible method for your main life phone.
They have your identity the moment you put the sim in the phone. The phone have unique identifiers that are recorded when sold.
Buy the phone used and/or with cash. And never put any SIM card in it that can be linked back to you or someone you know.
All the apps on your phone have access to the phone identifier. As well as other information, like your Google account. It’s pretty trivial to tie a phone to you.
That would require law enforcement to obtain the recording and have a reason to do so
I mean, yeah? If I’m buying anonymous phone credits, the police probably has a reason to go looking for me.
Act itself is not illegal… Police wouldn’t care un less you are already on Santa’s list… But it would not be police either but rather internal spooks who track that list.
