Average 4G mobile broadband speeds on Three's network now reach 17.8Mb, the service provider has claimed.
According to Three, mean download speeds have increased significantly from 10.7Mb in December 2014, ensuring customers can benefit from an enhanced dongle experience.
On the firm's 3G network, consumers can now access typical speeds of 6.4Mb, up from just 0.8MB in 2007.
Consumers are now using an average of 3.4GB per month, up from a mere 18MB per month eight years ago.
Bryn Jones, Three’s Chief Technology Officer, said the firm's aim is to keep its customers connected wherever they are.
"Adding low-frequency spectrum to our network and enabling voice calls over 4G and Wi-Fi will mean Three customers can stay connected in more places than ever before," he stated.
"With roaming at no extra cost also available in 18 destinations, Three is doing more than any other network to give our customers a reliable, quality experience wherever they are."
