No update would be needed. Cellular is a builtin feature of the iPhone.
Provide a Screenshot of the Error.
A screenshot might help you get this investigated clearer. Take a screenshot on iPhone - Apple Support
Also, overview this link: If you see a Cellular, Ultra Wideband, or Apple Pay Issue message after an iOS update or restart
