I have a iPhone XR and have had since November 23. It was pre-owned but in good condition. I have been trying to get my Verizon to send a verification code but my phone will not receive it. I have nothing in my blocked list. I have been on the phone many times with Verizon and apple customer support. They can not figure out why I am not receiving them. What more can I do to try and see why I am not receiving them. I really would like to receive them since I got this phone and have always used apple iPhones on past.
