It is unlocked where you can choose whatever mobile provider you like. It has a SIM card in it ready for AT&T, Sprint, and a few others, but not Verizon. I had to have a SIM card shipped to me from Verizon before I could have mobile service on my iPad. (I was replacing a previous iPad with Verizon service.) I replaced the SIM card myself. It will take a couple of calls to Verizon if that’s your service. Also, buying it unlocked means you don’t have to sign up/pay for those lengthy contracts they try to hook you into. I can’t help you with the earbuds part... I use the Apple Pods. Good luck!
