I have a S20+ 5G, unlocked with service through Straight Talk. I recently switched out the AT&T Sim card for a Verizon. After the switch, the visual voicemail no longer works, the voicemail app no longer works, and I no longer get voicemail notifications. I can access voicemail through the contact list which is how I found out that I had 6 VMs.
Any suggestions on what I can do to fix any or all three of the issues?
