AT&T carrier setting 33.2 update on iPhone leads to constantly losing connection

After updating my iPhone 7 to the AT&T carrier setting 33.2, it constantly loses the connection and says "No service". Then it reconnects to "AT&T" and soon after loses it again. Does anybody have the same issue? What can I do, e.g. is there a way to reload the latest carrier settings assuming something went wrong during the update? I already reset all my network settings and rebooted the phone with no success.

Hello, @CyberAMS,


Let's see if we can restore your connection. Check to see if it's possible to update your carrier settings again. Go to Settings>General>About. If an update is available, you'll see that option here. If none is available or if reinstalling the update doesn't help, troubleshoot your iPhone with our Troubleshoot and Resolve Tool. Sign into your myAT&T account for more personal assistance and under Select your issue>Service/network issues, click on Internet and follow the steps provided.
