EE customers are now able to share mobile broadband data and other services across multiple mobile devices.
The broadband provider has launched its Shared 4GEE plans, which allow customers to use their monthly data allowance across dongles, tablets and smartphones.
This means there is no longer any need to have separate bills for each device - or pay for mobile broadband on both a dongle and tablet.
EE says its new plans are the first of their kind in the UK, allowing users to connect up to five separate devices on a single plan.
The firm claims this will provide "greater convenience and value" for 4G mobile services, with couples and family members able to use the same contract if they so choose.
Simeon Bird, Director of Propositions at EE, said that in "tough economic times", the plans can make a real difference to household budgets.
"Many of us have already started sharing more on a day-to-day basis, and to help make even further savings – we're launching the UK’s first shared mobile plans," he stated.
Mr Bird claimed the Shared 4GEE plans could help a typical family of four save almost £500 a year on their mobile service bills.
