I have a remote location were I have only satellite service, no cell service.
When I first purchased my iPhone 6 to my surprise I received messages (voice) left on phone at this location. I couldn't call people back but could text them over the internet.
Now after returning to the remote location I can not get any more messages left on my phone from voicemail. I am still getting text messages, which I also did with my iPhone 4S.
Did an update wipe out this ability or have I turned something off by mistake? I have all of my data turned on to WiFi.
