There are still some remote areas of Scotland which may not see improved broadband services without government help, according to BT.
The telecoms giant has won plaudits for its work north of the border in getting parts of the Islands and Highlands regions connected.
But speaking to the BBC, BT chief executive Ian Livingston says that there are some locations in the country which may not see faster broadband unless government investment is made.
Asked whether public funding was needed for the comprehensive roll-out of high-speed broadband in Scotland, Mr Livingston replied: "I think that may well be the case."
Continuing: "We will continue to work with local authorities, regional development agencies and the government as we did with the original roll-out of broadband."
An accelerating of broadband services is one of the 60 recommendations for the safeguarding of rural communities in Scotland made by the Royal Society of Edinburgh in a recent report.
