Voicemail not working. At the end of my rope
I just ported my number to Tello yesterday. I left Mint after 8 years because my voicemail stopped working a week ago and neither they nor I could fix it. After porting to Tello, I'm experiencing the same issues. Everything on my phone works fine. I just can't access voicemail at all. I don't want to use a 3rd party app for voicemail since I shouldn't have to.
Long press on #1 disconnects immediately. Same for dialing 123 and dialing my own number.
I've got the correct APN settings according to Tello's website.
I've rebooted my phone
I've reset my voicemail.
I've removed and re-seated the SIM card
I've toggled Airplane mode
I've reset network settings
I called Mint and they closed the ticket without telling because "no problem on our end." That's when I left. I opened a ticket with Tello and they haven't looked at it yet.
Phone: 2022 Motorola Moto G Stylus 5G. Bought this phone new 2023 and it worked flawlessly until voicemail stopped working last week. I'm in the US.
I'm honestly at the end of my rope here and asking for help. What else can I try?
