Week 1 (Day 0-7): "Get operational"

Get a U.S. phone number + data plan (SIM/eSIM):

Your first mission: get a working phone number. Without it, you can't verify bank accounts, receive important calls, or navigate safely. Most banks and government systems block VoIP numbers, so you need a real U.S. number via Tello or Mint Mobile eSIM ($15-25/month). This is your lifeline.
