I have MetroPCS. I set up my greeting earlier this week. I had bad reception so called their support and they 'reset the network'. Now I can't save my voicemail greeting. I get this error. I took the phone to a MetroPCS store, but they couldn't fix it. They only called tech support too. How do I fix it?
Also, my visual voicemail is not showing new voicemails. I manually called my voicemail by holding down 1, sent a voicemail message to myself, and hung up. It doesn't appear in visual voicemail.
I also called my phone from another line and left a voicemail, but it doesn't show up or notify me of a voicemail.
iPhone 5, iOS 10.3.3.
