I guess the Sprint phone comes with this voicemail app that I can't uninstall and that might be interfering with the voicemail function. I don't get any notifications and when I go to the Dialer's app settings, it does say "My carrier". If I press on the voicemail icon it does go to this App that shows "No message" and if I press on 1, it dials something but not the Voicemail and says the number can't be completed. I've looked everywhere in the settings but can't figure it out, any help or suggestions would be very appreciated! Thanks.
