I think that my iPhone 7+ should have the Visual Voicemail feature. Instead, I have to call into
Boost's voicemail to retrieve/listen to audio. Apple support says iPhone Visual Voicemail is a carrier
provisioned feature and a help page says Boost Mobile (US) supports it. The phone was previously
on another carrier so I've tried a carrier reset as well as resetting network settings. Neither of that worked.
Is there something else to do on my end or something within Boost's provisioning?
