I have the S9+ on Verizon and I wanted to know if there is a way to send individual contracts straight to voicemail. I thought this was an option in the past, but, seems to not be there anymore.
Blocking a number should, effectively, do just that.
So if you open your Contacts app, select a contact, and then tap the Menu button, there's no Route to Voicemail option any more?
You can use a third party app such as Hiya.
