In case you have ever had a cloud hosting account before or you've dealt with any kind of online service, you're probably well aware from personal experience that for certain things it is better to consult with a live person on the telephone rather than exchange support tickets or emails. If you'd like to learn more about a service before you order it or in case something small needs to be made, for instance, it is really easier and quicker to get it done in real time. When you are able to get hold of representatives over the phone, it's also very likely that you're dealing with a real hosting provider, not just a reseller. The type of support that you will get over the phone may differ between different suppliers - from very general issues to professional technical support. Generally most of the suppliers offer pre-sales assistance and 1st level telephone support, while more complicated tech issues are resolved via electronic mail or tickets.
