Skype may be best-known as a video calling app, but it has several other features you can use if you don't have access to a webcam or don't want to make use of it. These alternative communication methods work across Skype's desktop and mobile applications to keep your conversations in sync.

Audio Calling

Calls made on Skype can be audio-only. This covers free Skype-to-Skype calls (to and from the desktop and mobile clients), and you can also ring landlines and mobiles from Skype by purchasing Skype Credit. Group conference calls and a free voicemail service are also available.

Instant Messaging

Skype also provides a free instant messaging service comparable to other platforms like Facebook Chat or Yahoo Messenger. You can chat with contacts one-on-one or create group chats with many people at once. With Skype Credit, you can also use the service to send SMS messages at low rates.
