But if you want to call someone on their mobile, you need to buy credit from Skype. Calling from Skype saves you money and you should do it often. Do you know how you could call a contact in Skype? You can search for the contact that you would want to call and double clicking on the Contact to call them. In case you need more assistance with this, we have a video that will help you with that. Happy calling!
