24 hour delay on voice mail delivery on iphone 7. Very disruptive, as I am looking for a job. Woke up this morning and had 3 voicemails from yesterday, one that wanted to interview that day. Can anyone help?
Do you have another phone in which to try the sim? If yes, insert the sim into the other phone and leave yourself a voicemail message and see how long it takes to receive voicemail notification.
