Issues with Cellular following update to IOS 12.5.5 on iPhone 5S

iPhone 5S recently updated to IOS 12.5.5. Now cannot access cellular (wireless still works) and I see the following messages "Mobile update failed" and after trying a factory reset "iPhone requires Service." How can this issue be fixed?

Welcome to the Apple Support Communities.


Please see: Manually update your carrier settings on your iPhone or iPad - Apple Support.


You may also need to contact Apple Support, Get Support, or your mobile carrier.
