Hello @mooremelons3,


We'd be more than happy to take a closer look into this issue that you're experiencing with your cell phone.


We'll need some more details in order for us to better assist you:


  • When you say that you were network unlocking your cell phone but didn't do it correctly, what specific steps did you take to do this?
  • Were you attempting to unlock your cell phone from the AT&T network, or was this device originally on a different carrier's network and you were trying to use it with AT&T?
  • Did you get your SIM card from AT&T, or different wireless carrier?

Please let us know.


We'll be patiently awaiting your response.
