I recently purchased a used Samsung Galaxy note 10 plus from an individual that stated they could not afford the phone they had recently purchased and they said they would like to get some of their money back by selling it to me. Thus way they woukd have more to spend on bills.
I bought the phone and I just put my sim card from att prepaid into the phone. And it wont work at all. Says it has service but cant call or text and no data. Plz help. I spent almost 500$ cash on the new device.
