That usually indicates a hardware failure of the radio microcircuit that controls both Wi-Fi and Bluetooth. You should first verify that it is not a software problem with the following steps (stop when one fixes it):
If None of these fix it your phone has a hardware problem.
If the 3nd one fixes it you can restore your backup -->Restore your iPhone, iPad, or iPod touch from a backup - Apple Support and check again. If the problem comes back you have corrupt data in your backup.
Bluetooth spinning wheeel and WiFi on off is greeted out
