I can receive/send calls and texts but no mobile data

I recently got a renewed at&t phone from amazon, it is the galaxy s20 5g. it was supposedly unlocked but when I put my old sim card in (straight talk sim from galaxy s10) the device was locked from it, so I proceeded to unlock it myself with the network key and was successful. Upon realizing that I do not have internet when I turn the wifi off, I checked the sim status and the mobile network state is disconnected, how do I fix this?

Hello, @isaiah2670! We want to help your device connect to mobile data!


We need a little more information to be able to provide the most accurate information such as:

  • Are you trying to connect to the AT&T network or the Straight Talk network?
  • Have you also tried restarting the device, power cycling the device can correct mobile network connection errors? 
  • Does the device have the most up to date network software, making sure the software is up to date can correct common network errors as well.

You mentioned the device was unlocked with the network key, but did you meet all the device unlock eligibility requirements?


We look forward to your response and welcome any other questions you may have.


Thank you for reaching out to the AT&T Community Forums!
