BT Broadband customers are being offered the chance to buy discounted mobile handsets with an increased data allowance.
The BT Mobile 4GB Plan is a 12-month contract that offers a £50 discount on selected devices in the BT Shop.
As part of the offer, the data allowance has been doubled from 2GB to 4GB.
Subscribers will also have unlimited access to BT Wi-Fi, 500 minutes and unlimited texts, as well as a £20 gift card.
The contract costs £10 a month, which includes the £5 monthly discount for living in a home that has BT Broadband.
BT's broadband services have been in particularly strong demand in recent months, as it reported recently that it achieved 79 per cent of broadband net adds between March and June this year..
