Personally, I think Samsung has one of the best ways of dealing with your voicemail. In addition to offering a quick and easy way of acessing your voicemail, Visual Voicemail will let you jump right into the message you want to listen without having to listen to each message until you get there.
Sometimes, when the phone is not picked, the caller is automatically redirected to the voice mail. That means that when someone calls you, he or she will hear some dial tones before going to the voice mail where they could record their message. In Verizon, you can actually set the number of rings before voicemail.

However, most networks do allow you to adjust the length of time that the phone rings before switching to voicemail by dialing in a long code number. On Vodafone this is **61*121*11* followed by the number of seconds and then the hash symbol (#). So to set your phone to ring for 20 seconds you’d dial **61*121*11*20*.
With all the amazing different types our iPhone’s can do, we sometimes forget they are also a phone. While calling people isn’t nearly as common as it once was, it still happens and your phone still needs to be able to make and receive calls. However, there are bound to be times when you are not by your device when a call comes through. But instead of just missing the call entirely (which could be incredibly important), why not set up voicemail on your device. While it might sound like a daunting task, it really isn’t that bad or hard to create. However, if you are confused about how to set up voicemail on your iPhone 6S, worry no more. This article will go into how to set up your voicemail on your device with ease.
