Issues connecting to cellular data on iPhone After Update

Today I updated my iPhone form iOS 16.0 to 17.4. When I opened my phone I found that I was no longer connected to my cellular data. When my wifi is off and my cellular is on, I get popups saying “Cellular Data is Turned Off.” I also keep getting popups to update my carrier settings but when I click update it shows me the popup a second time. Then, it appears again a few minutes later. Something to note is that I am currently on roaming since I am out of my home country.


So far I’ve tried:

  1. restarting my phone
  2. resetting network settings
  3. deleting any vpns in settings
  4. updating my carrier in settings (this did not appear)
  5. manually setting my provider since i’m on roaming
  6. contacting tmobile support (they said ask apple)


Any idea what I could do to fix this issue? Haven’t found anyone on here with the same problem.

I was on the phone with apple last night. Figured out that plugging the phone into a computer, backing it up, then doing the factory reset, update download and install, and restore all through apple devices fixed the problem.
