If your hosting supplier supplies live chat support, you are able to talk to a representative live and find out useful information or get a problem resolved in a timely manner. The basic advantage of using chat compared to calling to talk to a live person is that you need just a computer with web access, which means that you will not pay any rates in the event that you're in a different country or state. Furthermore, it is a lot easier to copy and paste info like domain names, usernames or error messages i.e. details which are sometimes hard to share with the other party on the telephone. The real-time chat is also a considerably faster way to contact the hosting company's support team in comparison to using a ticketing system. What's more, when some issue needs a bit more time to be resolved, you're able to do something else while you wait for support on the live chat, which means that you will not lose time - something that is not possible when you're on the telephone.
