Its most disappointing that non verizon phones on the verizon network cannot use visual voicemail. Unless there is a fix that I don't know about. I have spend several hours with Verizon's customer service and nothing works. If anyone has a fix, I would like to know about it. Phone is an S20+5G.
We deeply apologize for this experience with our service on your phone. We are very sad to say that only our Verizon branded phones are able to use our visual voicemail service, phones from other providers will not be able to use all of our services.
