my wifi and bluetooth are greyed out, please help, iphone

If both Wi-Fi and Bluetooth are greyed out that usually indicates that the radio chip that supports both of those networking services has failed. This is a hardware failure. Contact Apple support to discuss repair options.

As a test, back up the phone, then restore it to factory settings→Restore your iOS device to factory settings - Apple Support. Set it up as a new phone and see if Wi-Fi and Bluetooth are still greyed out. If they are it is definitely a hardware failure.

If they work normally when set up as a new phone try restoring the backup you just made→Restore your iOS device from a backup - Apple Support

As a Last Resort:

E. Restore form a Backup:

Have a backup of your iPhone? If you are not concerned with losing data, then restore your iPhone from a backup that was made when Wi-Fi was working. Prior to restoring, backup your iPhone, incase anything goes wrong with the restoration.
