Phone giant EE has confirmed it will start to roll-out its 5G mobile network coverage across the UK at the end of this month
The BT-owned telecoms operator will be the first in the country to offer the new high-speed service.
It will initially launch in London, Cardiff, Belfast, Edinburgh, Birmingham and Manchester on May 30.
More locations are scheduled to follow before the end of the year and into 2020, including the "busiest parts" of Bristol, Coventry, Glasgow, Hull, Leeds, Leicester, Liverpool, Newcastle, Nottingham and Sheffield.
5G technology is the next generation of mobile network and is expected to offer internet speeds several times that of current generation 4G.
EE announced earlier this year that it would test its 5G mobile network during Glastonbury as part of its trials of the technology.
It said it will install five temporary masts across the Worthy Farm site, which will enable festival-goers to connect to 2G, 3G, 4G and new 5G networks.
EE confirmed a number of 5G-ready smartphones would be available on its new network, including devices from Samsung, OnePlus, LG, HTC and Oppo.
However, the operator added it would not include Huawei devices. It stated: "until we get the information and confidence and the long-term security that our customers - when they buy those devices - are going to be supported for the lifetime that they've got the device with us".
The omission of Huawei comes after Google confirmed compliance with a US government order which forces American companies to stop trading with the Chinese firm.
The block means Google will stop supplying its Android operating system - which powers Huawei phones - to the company's new devices, however it will continue to support phones already on sale.
