Bests & Worsts Reviews from Amazon

Received the phone and took it to AT&T to have them swap the SIM card from my old phone to this iPhone 8+. Couldn't make outbound calls or messages, only iMessages on WiFi. Called AT&T and they said the phone was locked in their system and had been flagged as Lost or Stolen, and they wouldn't unlock it without the original purchaser's consent. Phone un-usable.
