Mobile operator O2 has turned on 5G in Cheltenham and Bournemouth.
The towns are among a number of new areas in the UK which will now be able to access the high-speed network.
Other new locations include Southampton and Doncaster, while O2 has increased its 5G coverage in cities such as Bristol, London, Birmingham, Glasgow, Liverpool and Manchester.
O2 said 5G was now available in 150 towns and it would continue the roll out across the UK, with urban areas receiving added coverage.
It also said it would continue to monitor sites such as hospitals and supermarkets to make sure they stayed connected.
Derek McManus, chief operating officer at O2 said: “We are delighted with the progress of our 5G rollout and to be able to offer customers in over 150 locations the benefits of our high-speed network.
“Once again we are facing tough lockdown restrictions and we are focused on ensuring we meet the demand for increased network capacity and reliability to keep everyone connected during this time.
“We’re also proud of leading the charge from an environmental point of view, with 67% of our estate powered by renewable energy as we work with landlords to encourage usage of more renewable sources.”
Last week, O2 announced a partnership with the Department for Education to offer 40GB of free data a month to support home schooling families and enable disadvantaged pupils in years 3 to 11 to Get Help with Tech and continue their learning from home.
