What do they do?
Video calls (sometimes known as video conferencing or virtual communication) let us see and speak with others, using our phones or computers. Because we can see who we are talking to, voice and video calling can seem more personal than text-based options.
Using these tools, you can make a phone call using the internet. They use video to transmit a live picture, so you can see and hear the people you're speaking with. You'll need an internet connection - either Wi-Fi or using your phone's data. Bear in mind that if you are using mobile data, video calls can be quite expensive.
Just like text-based tools, there are different types, to suit different needs. In this chapter, we'll compare the three main types.
Dedicated video calling apps and software
These tools, like FaceTime (only for iPhones and iPads), Skype and Zoom, are specifically for voice and video calls. They're all available as mobile apps, either built into your phone or quick and easy to install. If you don't want to install an app or want to use your PC or laptop for calls, you can use Zoom and Skype from your web browser too.
You can use these to call someone when you need to, and you can speak with (and see) more than one person at the same time. The way you add more people to the call varies depending on the tool. Some allow you to schedule your calls - useful if you want to book a regular catch-up with a group of friends.
Social media
You can use social media for video calling as well as other things, like instant messaging and sharing photos. We use apps like WhatsApp (only for phones) and Facebook's Messenger for both video and voice calls.
You need to install these mobile apps before you use them. When you set up the app, it will ask to access your phone's address book, or list of contacts. Allowing this access means you can see your contacts in the app and see who is online.
These apps are best for 'instant' calls rather than pre-scheduled ones. They're great for quick social chats. Although you can have group chats through these channels, they work best for one-to-one conversations.
Video conferencing sites
You might use these web-based tools at work, or for learning. They're the best choice if you have lots of people who need to get together online. Most people use PCs or laptops for these, though some are available as mobile apps too. Examples are Microsoft Teams, WebEx and GoTo Meetings.
If you're invited to join a webinar, virtual meeting or other online event, you're likely to use one of these sites. You'll get an invitation (usually by email). This has a link that you use to join the meeting or event.
You don't need to install the software but there are a few steps to go through before joining an event in this way. Read the instructions on the invitation email carefully, and allow some setup time before the event is due to start.
