How can I fix my cellular data it says error?

Hi japri49,

We'd be happy to see if we can help with getting your cellular data issue headed towards a resolution.

Which error are you receiving? If you head to Settings > Cellular (may be listed as Mobile Data), do you see the following: 'An update is required to use cellular data on this iPhone.'

If so, it looks like you may have come across the page for this issue, but if not, try the steps in the 'What to do next' section: If you see an Update Failed or Apple Pay Not Available alert after iOS update or restart

If the issue persists after that, servicing would be required. You can start a support request with Apple Support to explore any options available here: Get Support

Be sure to back up your iPhone ahead of time as well: How to back up your iPhone, iPad, and iPod touch

Take care!
