Fix iPhone Microphone modes are currently unavailable

"Microphone modes are currently unavailable” is a problem for many iPhone users trying to activate Voice Isolation or Wide Spectrum during voice calls.

Normally, all models of iPhone XS or later should support this voice filtering feature during phone calls with the release iOS 16.4.

Until iOS 16.4, Voice Isolation si Wide Spectrum they were only available for calls FaceTime. Apple has extended this feature, but apparently, many users cannot enjoy it.

Unfortunately, Apple does not offer a solution to solve this problem. Many users complain on Apple's official forum that the error appears for every mode they try to activate for the microphone. "Voice Isolation mode are currently unavailable"Or"Wide Spectrum mode are currently unavailable".

From what I tested on an iPhone 12 Pro, iPhone 13 Pro and iPhone 14 Pro, the solution is very simple. Start a call with someone and try to activate "Voice Isolation" or "Wide Spectrum". If the function is not available, close the call, restart iPhone, then call again. In my case it worked on all the previously mentioned iPhone models.
