Calls and chats to other users within the yuilop network service are free of charge. Unlike most other VoIP services, yuilop does not charge for off network communication. Calls and SMS to landline telephones and mobile phones use virtual credits that are earned for free through participating in promotional activities and using the app. Yuilop does not require credit for national calls and SMS in the U.S. Yuilop has additional features, including instant messaging, group chat, and location, and photo sharing. Competitors include Skype, Viber and Google Voice. OverviewYuilop was created by former simyo CEO, Jochen Doppelhammer in November 2010.[5][7][8] Yuilop's headquarters are located in Barcelona, Spain[9][10] and the app is available in over 200 countries including the United States, United Kingdom, Germany, Italy, Spain, Israel, and Mexico.[11] The app currently has approximately 5 million users and is available on Android, iOS, Windows Phone, BlackBerry OS.[12] As of July 2013, Yuilop has raised approximately $9 million in funding from investors such as Nauta Capital,[13][14] Shortcut Ventures GmbH,[15][16] Bright Capital, and the Spanish government.[8][17] Yuilop's services are split into two main categories:
FeaturesYuilop provides free calling and texting between Yuilop users as well as to mobile and landline numbers not in the Yuilop network. Yuilop allows these registered users to communicate through instant messaging, SMS, voice chat, and calling with yuilop.me. Yuilop's text chat client allows group chats, emoticons, photo sharing, and location sharing. Yuilop.meYuilop.me is an option to receive a virtual mobile phone number. The number can be used across devices with access to the internet and is not tied to a SIM card or an operator. Yuilop.me is currently available to Yuilop users in the United States, the United Kingdom, Germany and Spain. CreditsCalls and instant messages made to other Yuilop users via the app are free and unlimited. Calls and SMS made to mobile phones and land lines use "credits". Credits are acquired by:[18]
Version 1.9 of the iOS app also allows users to purchase credits.[19] The number of credits used to call mobile phone and land lines is determined by the location to which the call or SMS is sent. Sending calls or SMS to mobile phones requires no credit in or between some countries, such as the United States.[20] SecurityYuilop uses a 2048 bit encryption to encrypt data traffic and call signalling over any transport medium (Wifi, 2G, 3G, 4G LTE). A STARTTLS extension is used through a Transport Layer Security protocol.{{citation needed|date=September 2013}} See also{{portal|Internet}}
