I don't receive voice mails until 2-4 days late. Then they all appear at once. I use this Iphone 6Plus for business and this problem is disastrous. the delay has happened off and on for years but in the past few weeks none of my voice mails arrive promptly. Some of the delayed VM calls were received while I was on a wireless network, other times when on cellular service. None of the many other questions about the same issue in this forum show a satisfactory answer, but I am still asking how this serious problem can be resolved.
