OR:

Skype offered a number of features based around calling (both free and paid), messaging (including instant, voice and text messaging (SMS)), video chat, and file and screen sharing. The following is a partial list of
Skype Skype () was a proprietary telecommunications application operated by Skype Technologies, a division of Microsoft, best known for IP-based videotelephony, videoconferencing and voice calls. It also had instant messaging, file transfer, ...
's features:


Instant messaging and chat history

Skype allows users to send
instant messages Instant messaging (IM) technology is a type of synchronous computer-mediated communication involving the immediate ( real-time) transmission of messages between two or more parties over the Internet or another computer network. Originally involv ...
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. Although Skype allows sending SMS messages, it is not possible to receive SMS messages on Skype so users need a different way to receive responses to the messages they send using Skype. This has been a cause of angst among user who purchase Skype as an alternative to a mobile phone because Microsoft will not refund any purchases even for users who discover this missing feature only after purchasing multi-year contracts. Other than in user complaints on the Microsoft Skype forums, there is no mention on Microsoft or Skype websites that when they say "Send SMS messages," that is just what they mean: users can send but they cannot receive SMS messages.


Chat history

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 into 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. Skype allows users to delete all saved conversation histories for the device.


Emoticons and formatting

Users can send about 254
emoticon An emoticon (, , rarely , ), short for emotion icon, is a pictorial representation of a facial expression using Character (symbol), characters—usually punctuation marks, numbers and Alphabet, letters—to express a person's feelings, mood ...
s that are displayed either statically or animated, depending on user's settings. There are also hidden emoticons, 241 flags and 63 other. On special occasions, Skype introduces ''featured emoticons'' that are later either left as standard (''anger''), left as hidden (''mooning'') or removed (''captain''). Sending an empty message is not possible. Automatic conversion of text into emoticons cannot be disabled. Formatting text is possible: *text* creates bold text, _text_ creates italic text, text applies monospace font and ~text~ creates strikethrough text. Writing @@  at the beginning of a message will disable any formatting in the message. Placing two exclamation points and a space (!! ) at the beginning of a message will send the entire message in monospace font. A more convenient way to disable formatting for small pieces of text, is to use ```text``` instead of text. Turning off formatting permanently can be achieved with the command /wikimarkup off.


Quoting

Users are able to quote other messages by copying them and pasting them into a new message. A quote shows the message, the original sender, and the timestamp of the original message. The feature is seen as controversial and often useless because people have found ways to create custom quotes.


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.


Outgoing calls

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 per minute for most developed countries, and as high as per minute for calls to the

numbers. 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

. 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.

Skype Premium

''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.

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 2015, 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

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. In February 2017, Microsoft announced plans to discontinue its Skype Wi-Fi service globally. The application was delisted, and the service itself no longer functioned after March 31, 2017.

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".

Skypecasts

''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 control who was able to speak. The "host" would always remain in control, and could invite people into the speaking area. There was the functionality to mute and eject, both speakers and listeners, or add more people to speak from the listener section. Skypecasts did not support chat windows to share text information (such as URL) with participants. The Skypecast feature was removed in 2008.

SkypeFind / business directory

''SkypeFind'' was a community-generated directory of business reviews in Skype 3.1. The feature was removed 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.
