A mobile phone that predicts Welsh text messages was unveiled today.
The feature will be included on the first Welsh-language mobile. Users will also be able to scroll through Welsh menus.
A touch-screen Samsung S5600 containing more than 44,000 Welsh words will be available from Orange next month.
Heritage Minister Alun Ffred Jones congratulated the two companies when he unveiled the phone at the National Eisteddfod in Bala.
"This development shows that they recognise not only the benefits of offering services through the medium of Welsh but also the importance of responding to the needs of their customers here," he said.
"It's important to be able to have services and technology available in the language so that people can live their lives through the medium of Welsh."
It follows an Irish-language phone launched by Samsung last year.
Orange head of retail Sian Doyle said: "Orange is really proud to be the first network to introduce this truly innovative service to Welsh speakers.
"This initiative is part of a broader commitment by Orange to provide Welsh speakers with more choice."
