Homes and businesses in every telephone exchange area on Anglesey can now take advantage of super-fast broadband through the Superfast Cymru programme.
The first fibre street cabinet has gone live in Brynsiencyn, allowing local people to take advantage of next-generation connectivity services.
At the start of 2015, 60 per cent of premises on Anglesey - which lies across the Menai Strait from North Wales - can sign up for super-fast broadband.
This figure should rise to at least 96 per cent of properties by spring 2016.
Julie James, Deputy Minister for Skills and Technology in the Welsh Government, said work is now taking place across Anglesey, bringing super-fast broadband to premises in every exchange area.
"The Superfast Cymru programme is making excellent progress in bringing fast fibre across Wales, often in difficult and challenging conditions," she stated.
Ed Hunt, Superfast Cymru Programme Director for BT, said the company's engineers have worked "incredibly hard" to increase access to fibre broadband on Anglesey.
"Now that the network is well on its way to being completed on the island, I would urge homes and businesses to place their order with an internet service provider so that they can start taking advantage of these new superfast speeds," he added.
