A:AnswerI purchased one (colour: green) in August, and the phone had no signs of wear nor any demarcations. Battery health came at 99%. Overall, the price seems well worth the quality of device, as well as the subscriptions.
A:AnswerYes you can, once it is unlocked and you have a nano SIM card. I inserted my nano SIM and the device immediately connected to my carrier; there was no need for any set up.
