Hello Chuck2j,

Thank you for using Apple Support Communities! I understand that you're encountering an error when using mobile data after updating your iPhone SE to iOS 12. It's important that you have full use of your iPhone and you've come to the right place for help.

Since you've already done some extensive troubleshooting to resolve this error, let's start by checking you have an available carrier settings update next:

Update your carrier settings on your iPhone or iPad - Apple Support

If the message appears when you're in an area that is considered roaming by your carrier, confirm that you have a plan that allows for roaming with your carrier and that Data Roaming is on from Settings > Mobile Data. If the behavior persists, you may want to try a different SIM card and contact your carrier to confirm your data plan is active and that there are no outages in your area.

Cheers!

Hi, yes. My issue was related with my network carrier. The automatic charge was attempted during the time my phone was updating ios, but didn't went through. As soon as I made the payment everything started to work.
