Just wanted to update this issue.
Tracfone stated that I would have no problems once the shutdown happens but I did not want to take the chance of losing my phone number and data amounts that I have with the company, so I transferred my service to T-Mobile. VOLTE is working.
Just one question, not related to the issue.
Now that I am on T-Mobile, I want to use Visual Voicemail.
Can someone on T-Mobile tell me what app they use? The VM app in the phone app just invokes a phone call to Voicemail.
