Carrier update

[Scullyxo]

My son’s cell service stopped working with cellular displaying "An update is required to use cellular data on this iPhone." I have backed up and updated my phone and cellular service still not working. Tried resetting network setting and same issue.

please help !

The Apple device app shows that the iPhone software is up to date 

is there anything else I can try ?

should I try restore iPhone ?

I looked Settings > General > About but no carrier information is listed like it is in my phone (iPhone 11)

I will try again with my laptop    I didn’t have the Apple devices app so I am just downloading right now.  
thanks

I put my SIM card in his phone and his sim in mine.  I had no issues connecting to a cellular network on my phone but his still had the same issue.  
I tried updating his phone last night with my windows computer already to try and fix the issue

@Scullyxo - The carrier profile should be at Public Mobile 58.0 as shown here:

Also it is in Settings > General > About.

And to update carrier profile plug the device into a Mac and open Finder and click on "Update" or on the Apple Devices app on Windows and click "Update."

And sometimes it should show up if you don't update for a while or the carrier forced out a profile update it should pop up something.

Yes I can put my sim in the phone to test it.  I will try that and let you know
