My dad is on the 3 network & earlier we wanted to listed to a voicemail he'd saved today. My dad is 100% sure he saved the voicemail, but when I go to voicemail it tells me that there is no new voicemail & gives me other options, none of which are to listen to the saved voicemail. He did get a text saying there is going to be planned maintenance this week. But I don't see how that would effect voicemail.
