Hi @Skynight,


Thank you for reaching out. We'd love to take a closer look into this for you.


To better assist, we want to know:

  • what exactly you mean by your number showing as unknown
  • are you activating a new line or installing a new SIM for an old number
  • are you using an AT&T branded or unlocked device
  • what AT&T wireless plan (prepaid/postpaid) do you have 

You can also follow the instructions in the link to activate your line.


Try this and please reach back so we can assist further.
