If you ported your number from Verizon postpaid to a Verizon MVNO (like US Mobile Warp, Visible, or Total Wireless) and completely lost your Visual Voicemail (VVM) or voicemail notifications, you are likely trapped in a known sync glitch.
The Root Cause: The Verizon "Death Grip"
When you request a line re-provision from your new MVNO, it sends a standard configuration sync to the backend. However, because Verizon often retains stale routing history on legacy port-out numbers, the automated sync gets ignored or swallowed by the core vendor database. Customer support agents will run the same re-provisioning loop endlessly, and it will never stick.
To fix this, you have to bypass standard administrative channels and force a high-priority state change in the carrier's security layer.
The Workaround: Forced Security Exception
Instead of begging support to fix it, you can engineer a controlled crash of your mailbox profile to force a complete database flush. Here is the exact sequence to get it working:
Trigger a Hard Lockout: Dial into your standard voicemail box manually from your phone keypad.
Fail the PIN Interrogation: Intentionally enter the wrong PIN repeatedly. Keep guessing incorrectly until the carrier's automated system completely flags the account and locks you out for security reasons.
Contact the MVNO Support: Reach out to your new carrier's support chat. Do not ask them to "fix visual voicemail." Instead, simply state: "I locked myself out of my voicemail box by entering the wrong PIN too many times. Please send a hard reset/clear to my voicemail password."
The Database Flush: When the agent executes the password reset command against a hard security exception, the carrier's core system drops the active session state entirely, flushes the stale authentication token, and completely rebuilds the voicemail profile metadata from scratch.
Re-provision Your Device: Once the password is reset, open your Android/Pixel Phone app settings, navigate to Voicemail, toggle Visual Voicemail off, wait 60 seconds, and turn it back on. Within 24 hours, the new routing tables will permanently stick, and your saved messages will download automatically
