JT will connect every home in Jersey to high-speed fibre-optic broadband by 2018, following some project delays.
The telecoms giant say this is only "six months behind schedule".
Currently, only 70% of islanders have been given access to Jersey’s new fibre-optic network.
Daragh McDermott, JT’s Director of Corporate Affairs, blames the delay on 3,000 new homes that have been built since the start of the project in 2012.
JT have reassured islanders that they are progressing as quickly as they can.
However, the project - known as Gigabit Jersey - is said to be one of the top schemes in the world for fibre-optic connectivity.
JT expects to have connected over 37,000 properties to high-speed broadband by the end of the roll-out.
