As someone who hasn't been motivated in the past, how disconnected from other means of identification is such a burner phone?

Are the cameras watching the purchase? Can you pay cash? Is any record beyond a sales receipt generated?

It's no more or less disconnected than any other store purchase. You can assume there are cameras in any store. You can indeed pay cash. The only records generated are the usual sales records, and if you're concerned about minimizing those, then you use the same mitigations that you'd use with any other purchase.

Personally, I'm not concerned with that level of anonymity, though. I just don't want to give my actual phone number to random companies.
