Disable T-Mobile voicemail to text? I currently get a text message for every voicemail I receive on my iPhone, how do I turn that off?
I already have visual voicemail within iOS, so there’s no need for an additional transcript of my voicemails.
On Android, they offer an app for managing voicemail but their support pages and forums don’t contain instructions for how to turn this off on an iPhone. This is a common problem that many customers complain about having a hard time fixing.
In the T-Mobile app:

Open “Account” tab
Click “Profile settings” link
Select “Block calls and messages”
Select “Block Other”
Turn on “T-Mobile Voicemail to Text Block”
