EE is to create 300 new jobs in Derby as part of plans to enhance its UK-based customer service offering.
The broadband provider - which is aiming to become the 'number one' company for customer service in the telecoms sector - is partnering with Webhelp UK to create the roles.
Earlier in 2014, EE committed to improve customer service levels with the return of over 1,000 service roles to the UK from overseas.
The firm opened a new contact centre in Derry/Londonderry in May, and the new jobs in Derby represent the second stage of its expansion plan.
EE is also tripling the size of its apprenticeship programme, by recruiting more than 1,300 young people by the end of 2015.
Over 500 apprentices who have completed the programme have already been hired by the broadband provider.
Olaf Swantee, Chief Executive Officer at EE, said: "The opening of our new call centre in Derby is the second UK contact centre we have opened in just a few weeks.
"It underlines our investment in the UK as well as our determination to make EE number one for service in the telecoms sector."
Mr Swantee noted that the benefits for its customers are clear, as the performance of UK call centres is shown to exceed that of those overseas.
"But, just as importantly, today’s announcement shows our significant investment in the UK is not restricted to our network and demonstrates a continued commitment to job creation for communities across the country," he added.
Communications Minister Ed Vaizey has welcomed the announcement, describing the new contact centres as "great news for both Derby and EE customers".
He said EE is making "a real commitment to the UK" by recognising the strength of the British workforce with its new customer centre in Derby.
