EE will switch on its 5G service in six UK cities on 30 May, the first mobile network in the UK to do so.
People in London, Cardiff, Edinburgh, Belfast, Birmingham and Manchester will be first to get faster services with plans for 10 more cities to be added this year.
Prices for 5G – which will require new handsets – will start at £54 per month for 10 gigabytes of data.
EE confirmed that its range of 5G phones would not include Huawei.
“We’re pausing the launch of the new Huawei 5G smartphones coming to market,” said a spokesman, adding that EE is working with both the Chinese firm and Google to “make sure we can carry out the right level of testing and quality assurance” for customers.
