I am from India and our network (vodafone) doesn't provide voicemail service and i feel i need it badly. i miss lots of calls, my older network from other state used to serve me this but by making calls and listening to voicemail and getting navigated through buttons by using numeric commands. is there any app or settings so, i wouldn't get any need of service. iphone could pick my call and say user is busy and save voicemail in phone memory, so i could get unlimited voicemails saved in my phone.
