iPhone 6 sim no longer registers to the network after the iOS 12.4 update

I am registered with MDM at my work and the ploicy forced me to update my phone to 12.4.

Until last night before the update every thing was working but not the SIM will not register.


Wi-Fi - Works

Network - SOS Only


I swapped another sim into the phone and that too did not register

Upon trying the sim on other phone, network registers successfully


Already tried :

  1. Force Reboot
  2. Restart - Multiple time
  3. Network "soft" reset


iPhone 6

Start here, If you see No Service or Searching on your iPhone or iPad - Apple Support


You may also need to make a Genius Bar appointment for the phone.
