Yes it has the latest updates installed and still no change. Can text and data works but can't send or receive calls. And looked on at&t website and it is a compatible phone for att go phone/prepaid use. Galaxy A 50. 

Hey Smurd20 lets point you in the right direction.

Try these troubleshooting steps to help get your calls back to working.

Turn off your device and turn it back on after 15 seconds to reset your device and reset your network settings to refresh your network. Go to Settings>General management>Reset>Reset network settings.

• A common issue is that some or all LTE service may be toggled to ‘off’ within the device settings inadvertently.  This can cause both voice and data issues depending on the device.

To Resolve:

         Determine if the device is HD Voice capable If you are using Wifi calling, HD voice is enabled.

• • If no, you will need an HD Voice-capable device
  • If yes, but not AT&T branded, you may need to update device software.
  • Second:  For those experiencing loss of Voice and/or Data service, check the following settings and then power cycle the device. 
    • Apple - based on iOS version:
      
      • Settings->Cellular->Cellular Data Options->Voice & Data->LTE (select LTE option)
      • Settings->Cellular->Cellular Data Options->Enable LTE (select LTE option)
      • Settings->Cellular->Cellular Data Options->Enable LTE->Voice & Data (select)Voice & Data option)

                     Android

• • • Go to Settings > Connection > Mobile networks > Enhanced LTE services and select on.

Once complete, please ensure you power your phone off and back on to establish a fresh connection with the network.

We hope this information helps, and thank you for reaching out to the AT&T Community Forums.
