It does NOT mean you have to buy the phone from a US Cellular store. You CAN buy a phone from a friend, eBay, or wherever, but it MUST be US Cellular-branded. Also, phones can be direct-purchased from some manufacturer's, most notably Motorola. They will ask you who you're carrier is, and ship the phone US Cellular-branded. These phones can be activated.
