No Cellular Data After Updating to iOS 12.3.1

Since I've updated my iPhone Xs I've been having extreme problems with cellular service. After I first updated it I noticed that my cellular data was dropping out for extended periods of time -- hours on end. Then it would suddenly come back and I would get a flood of texts and voicemails. Later it lasted for over 24 hours so I contacted support and via remote screen sharing on my phone and MacBook Pro, we got the phone working again. But that only lasted for a day.


It's now been over 48 hours and cellular service has not come back. I have confirmed that it is not a sim card issue. I've done all the trouble shooting suggested many times over and nothing has fixed the problem.


This has never happened prior to updating to 12.3.1.


I'm in the US with T-Mobile as my carrier.


A few of us on Reddit with different models and carriers are having the same problem after updating. Has anyone here figured out how to fix this issue?


I NEED MY PHONE TO HAVE CELLULAR DATA


Edit: another note, the entire Cellular page in Settings is blank. Nothing in there with or without a sim card in the phone.

I have a passion and hobby to go through complete literature and review of all iOS releases and needless to say I haven't missed iOS 12.1.3, 12.1.4 12.2, 12.3 & 12.3.1 assessment published on various news media and on Apple web page including leading news magazines (Forbes & Fortune Magazines).


The major takeaways from this iOS 12.3 update is Apple TV, Kids TV, The app is available on Samsung TVs, tvOS has been updated, AirPlay 2, Apple TV app,


And iOS 12.3.1 includes bug fixes for your iPhone and iPad. This update:

  • Fixes an issue that could prevent making or receiving VoLTE calls
  • Fixes issues in Messages that could cause messages from unknown senders to appear in your conversation list even though Filter Unknown Senders is enabled
  • Fixes an issue that could prevent the Report Junk link from appearing in Messages threads from unknown senders

No where I could find any link on the problem of "Cellular Service Failure" faced by you. Introspect and have a complete and thorough check on the way you handle settings on your iPhone.


Read often for a peaceful life.


Solution. Contact your Carrier. The agency who provided you the SIM.
