Instant messaging and chat history
Skype allows users to send instant messages to other users in their contact list. Messages sent to offline users are stored on Skype servers and will be delivered to their recipients as soon as they come online on Skype. Chat history along with the message status will be synchronized across all user devices supported by Skype whenever the user signs in with the same Skype account.
Skype keeps user instant messaging history on user’s local computer and on Skype’s cloud for 30 days. Users cannot control how long their chat histories are stored on Skype’s servers but can configure that option individually for every their device. Once user signs-in to Skype on a new device the conversation history is synced with Skype’s cloud and stored locally. Skype allows users to remove or edit individual messages during one hour after sending; this affects messages already received by chat interlocutors as well as not delivered to them yet.
Calls between Skype and landline / mobile phone numbers
Skype users can call landline and mobile phone numbers (previously known as SkypeOut) using Skype Credit or a calling subscription. Additionally, users can purchase a Skype Number (previously called SkypeIn and Online Number) that lets contacts call their Skype client from a landline or mobile phone.
The ability to call landline or mobile phones from Skype was originally branded as SkypeOut, but this term has been dropped in favor of Calls to mobiles and landlines. Skype users can call phone numbers, including landline and mobile phones, for a fee using prepaid Skype Credit or a subscription (see below). This fee can be as low as US$0.02 per minute for most developed countries, and as high as US$2.14 per minute for calls to the island Diego Garcia.
In January 2007, Skype introduced a €0.03 connection fee for each call that connected to a landline or mobile number.
After 180 days of inactivity, a user's Skype Credit balance is deactivated; however, it can be reactivated.
Subscription calling plans
On 19 December 2006, Skype announced that there would be a new pricing structure in 2007. Details of a new scheme were released 18 January 2007. The initial press release was vague about the new scheme, but it did reveal that there may be a new connection fee.
In January 2007, Skype launched Skype Pro, a prepaid unlimited call subscription for calls that were made inside North America. Skype's unlimited calling offers unlimited calls to anyone, on any phone, within the U.S. and Canada, for a one-time (e.g. annual) fee. As of April 21, 2008, Skype Pro was replaced by new calling subscription plans, which don't require the calls to start from a certain country.
Skype offers several monthly plans that it calls unlimited. However, Skype limits these subscriptions to 10,000 minutes per month, 6 hours per day, and 50 telephone numbers per day. If one of these limits is exceeded, any additional calls are billed at regular rates and connection fees if the user has Skype Credit.
Skype To Go numbers
Users can set up a Skype To Go number which allows them to reach international phones numbers dialled from any landline or mobile. Skype provides a local number (the user chooses the area code) that then connects using Skype Credit to the number in another country. The service also provides the opportunity to dial any number abroad as well.
Calls to most toll-free numbers in Australia, Austria, France (+33 800, +33 805, +33 809), Germany, the Netherlands, Poland (+48 800), the UK (+44 500, +44 800, +44 808), Taiwan and the United States (+1 800, +1 888, +1 877, +1 866, +1 855, +1 844) are free for all Skype users.
Support for toll-free numbers in Canada was effectively removed in January 2012.
Caller ID for outgoing calls
Skype offers a feature allowing users to set the caller ID for outgoing calls to telephone numbers. Set-up verification involves sending an SMS text message to a selected mobile phone number, then typing that verification code into a web form. Since most regular home and business telephones cannot receive text messages, this feature is only available to owners of mobile phones.
Skype Number (formerly called Online Number and until 2010 named SkypeIn) allows a Skype user to receive calls to their Skype client (on whatever device) dialed from mobiles or landlines to a Skype-provided phone number. The number need not be in the same location as the user. For example, a user in San Francisco could create a local telephone number in London. Callers in London could then make a local call to reach that user (who answers on Skype in San Francisco).
Skype offers numbers in Australia, Chile, Denmark, Estonia, Finland, France, Germany, Hong Kong, Hungary, Ireland, Italy, Republic of Korea, Malta, Mexico, Netherlands, New Zealand, Poland, Romania, South Africa, Sweden, Switzerland, the United Kingdom, and the United States.
In Russia some companies, including SIP operators, provide direct numbers, redirecting calls to Skype.
Skype Premium originally bundled together a number of Skype's features including the selection of a calling subscription, the ability to make group video calls and the ability to screen share with up to 10 other people (person-to-person video calls are free), improved customer support and the removal of ads from the Skype client. However, the Premium product was removed in the summer of 2014 when group video calls and screen sharing were made free.
Skype Voicemail (now called Voice messaging) was released on March 10, 2005. This service allows callers to leave voicemail messages for Skype users who are indisposed. Leaving voicemail messages became a free service in 2012.
Video calling and screen sharing
Skype 2.0 and later, on Microsoft Windows (DirectX 9.0 or above required), Mac OS X, and Linux, supports video calling for Skype-to-Skype calls between two parties. Skype 3.6 and later on Windows and Skype 5.3 and later on Mac supports 720p high-definition video. Skype 5.8 and later on Windows and Skype 5.5 for Mac support 1080p high-definition video with the Logitech C920 webcam as well as the primary use of H.264 video codec instead of VP8 found in past versions. Skype 3.0.0 on iOS allows iPhone, iPad and iPod Touch users to call each other, as well as Windows, Linux and Mac OS X. Skype 5 supports group video calls. Group video calling - Skype. Sharing of external monitors is also supported via third party hardware.
SMS text messaging
Like many other instant messaging services, Skype clients can send SMS text messages to mobile phone numbers. In the United States, China, and Taiwan, Skype uses a "generic, pre-defined number" as the sender ID. In other countries, the message can be set to appear coming from a verified mobile number, allowing recipients to reply, or else show the first 11 characters of the Skype username. However, as of March 2011, Skype users cannot receive SMS, despite a continuing series of requests and complaints.
Costs are generally lower than standard SMS charges; for example Skype's UK rate per SMS message including VAT is 6.4p, compared to standard rates of 10p or 12p; for international SMS costs will be significantly cheaper using Skype.
Wireless hotspot network access
Skype WiFi (previously called Skype Access) allows users to pay a per-minute charge for Internet access at commercial wireless hotspots using Skype Credit. As of May 2010, Skype lists more than 100 participating networks. This replaced an earlier feature Skype Zones Beta which provided subscription-based access at wireless hotspots operated by Boingo and The Cloud.
Skype Click to Call (formerly called the Skype Web Toolbar) recognizes phone and Skype Numbers, and is available for Internet Explorer, Google Chrome and Mozilla Firefox on Windows. Such numbers on web pages are replaced with an icon that can be clicked to call the number using Skype, or right-clicked to provide further options, such as adding the number to Skype's list of contacts. The feature detects phone numbers automatically, but a web site developer can override the detection algorithm using a Meta element and mark the valid numbers individually.
A log file is created for each contact on a user's contact list. Log files are stored locally, meaning they are not available if a user switches computers. By default, the option to log conversations is disabled, but can be enabled in the tools / privacy panel.
The Macintosh version used to use the same message view style format as Adium, though with a different filename extension. Message view styles made for Adium could be installed for Skype, and they did not even need to be renamed. There were a couple of cosmetic bugs, but ignoring those, Adium styles worked without modification. This feature is not present in the Windows, Linux, and Pocket PC versions of Skype. This feature has been discontinued starting with Skype 126.96.36.199.
Not Available status
Since Skype 4, the "Not Available" status is supported. This status was removed in Skype 5.
Most Skype versions, including version 4, broadcast a status of "Not Available" after a configured idle time, but Skype 4 no longer allows the user to edit this setting. The only way for the user to configure this idle time setting is to edit the IdleTimeForNA setting in the config.xml file. Since this feature was removed in Skype 5, the edit setting no longer exists in the config.xml file.
Skype 5 and above display other users' "Not Available" status as "Away".
Skype let users set their presence indicator to "SkypeMe!" in earlier versions of Skype software. It invited calls from strangers. Setting one's status to SkypeMe! attracts a number of callers who want to practice a foreign language (usually English), in addition to the expected scammers and spammers. This feature has been hidden from being selectable starting with Skype version 4 and removed completely in version 5. Setting your privacy settings to "allow anyone to contact me" essentially does the same thing minus the presence indicator itself.
Skypecasting was released on May 3, 2006. Skypecasts were live, moderated conversations allowing groups of up to 100 people to converse, moderated by the "host" who was able to mute, eject or pass the virtual microphone to participants when they wish to speak. Skypecasts did not support chat windows to share text information (such as URL) with participants. The Skypecast feature was removed in 2008.
In late 2009 the company Skype for Power Gamers (S4PG) announced that in Q2 2010 it would be releasing both a client and server Skype add-on that will enable Skype end-users to host their own "Skypecast-like" auto-conference rooms.
Skype Prime was a beta feature in Skype 3.1. It allowed users to call lines that charged a per minute rate usually for advice on a particular topic. The feature has since been discontinued in later versions of the Windows and Mac clients.
SkypeFind / business directory
SkypeFind was a community-generated directory of business reviews in Skype 3.1. The feature was removed [clarification needed] Skype for Windows 4.x client. The business directory replaced SkypeFind but has also been discontinued from version 5.x of the Windows client.
Skype directory search
Earlier Skype versions allowed the user to search the Skype directory for random people to talk to. This feature was effectively discontinued since Skype 4.0. In current Skype releases you can only add contacts for which you know one of the following pieces of information: e-mail address, phone number, full name, or Skype name.
Viewing the entire conversation history
Old Skype versions allowed the user to view the entire conversation history with any contact. Current Skype releases only allow to view the history for the past three months.
