#2, you can walk into a Target and by prepaid SIM cards for about $15/each. You can also signup Google Fi for free, but they will need an address to ship the card to.
I've bought lots of prepaids in probably most European countries.
That is in direct violation of #1.
>#1 ....from somewhere without cameras
Target has cameras everywhere, even OUTSIDE the Restroom (for "Loss Prevention") and inside the elevators between floors, as well as at self-checkouts and customer service kiosks.
