If your web hosting company supplies live chat support, you are able to talk to an agent live and find out helpful information or get an issue resolved in a very timely manner. The key advantage of using chat as an alternative to calling to talk to a live person is that you will need only a computer with web access, so that you won't pay any charges in case you are in a different country or state. What's more, it is quicker to copy and paste info for example domain names, usernames or error messages in other words details which are sometimes hard to share with the other party over the phone. The live chat is also a much faster way to contact your hosting supplier's support crew compared to using a ticketing system. Last, but not least, if some problem needs some more time to be resolved, you can do something else entirely while you wait for support on the live chat, therefore you won't waste time - something that's not possible when you are on the phone.
