Operator enables Joyn subscribers to send instant messages to feature phone owners.
SK Telecom claimed on Monday that its joyn.T service has become the first RCS offering to surpass the 1 million subscriber mark.
The operator launched Joyn – the consumer-facing brand of the GSMA's Rich Communication Suite (RCS) – under the joyn.T brand in late December 2012. Since then it has tweaked the service so that data fees incurred from sending and receiving instant messages are not deducted from an end user's data allowance – a similar strategy that has been adopted by Joyn operators in Europe.
In addition, SK Telecom has also enabled subscribers to send Joyn messages to phones that do not have Joyn installed, which includes feature phones that are not compatible with the service. Any instant messages sent to a non-Joyn phone appear in the recipient's SMS inbox.
"SK Telecom aims to integrate all means of mobile communication into joyn.T to make it the most attractive choice for customers seeking an accurate and enriched communication service," said Wi Eui-Seok, EVP and head of product planning at SK Telecom, in a statement.
It will start by integrating joyn.T with its high-definition (HD) voice over LTE (VoLTE) service, which will become a standard feature on all phones sold by SK Telecom from March.
SK Telecom said it will also make its joyn.T APIs available to third parties in a bid to foster an ecosystem of entertainment, m-commerce and ICT services around its RCS offer.
