Hello @ ! Allow for us to provide some helpful suggestions to get your mobile device functioning correctly!



Before we continue, we would need a little more information from you to be of further assistance:

  • Was the phone sent to you in relation to our 3G Sunsetting Program or was this the result of another order?
  • "Neither phone works", is there another device that you have? If so what is the make and model of the device? What errors are you having with the separate device?
    • Please provide us with as much information as possible so we can work to resolve the issue.
  • We noticed you mentioned, your AT&T account is not Prepaid is that correct?
    • If so, then your AT&T Account will require your mobile device to include a compatible SIM card. Feel free to access the following link to get started on ordering one. 


We kindly await your response!
