Skype is being used in a Bridgend prison to allow young prisoners to keep in touch with their families.
Inspectors praised HMP Parc for supporting teenage inmates to have "quality contact" with relatives and friends.
A report on the young person's unit at the prison found that parents welcomed the contact and felt that their child was 'able to report issues to them quickly.'
There have been calls for technology to play a greater role behind bars to boost prison education programmes and the ability of inmates to stay in touch with their families.
Last year a Government-ordered review proposed that some prisoners should be able to use video-calling technology for "virtual visits".
HM Inspectorate of Prisons, which visited the unit in October, said it had shown "quite significant improvement" in key aspects, including safety, in the past year.
The watchdog found violence was falling but remained too high.
Overall, it was a "good report", Chief Inspector of Prisons Peter Clarke said, describing staff as "well trained, committed and confident".The young person's unit at HMP Parc in Bridgend, South Wales, is managed by G4S and holds up to 60 boys aged between 15 to 18.
