I was a spark customer for many years but I had the habit of never listening or clearing voicemails.

I switched providers to skinny a while ago and have been plagued with voicemail notification every time I go in and out of service. I live rural so it’s quite frequent.

I have an iPhone and have tried turning it on and off blah blah blah.

Skinny says there a no voicemails, so leads me to believe I have a phantom voicemail from spark.

Can anyone help with this? Or am I doomed to get a new sim and change numbers
