BT has launched what it claims is the UK’s cheapest home and mobile broadband package at just £15.65 a month.

BT is giving Total Broadband customers up to 8Mbps wireless broadband at home as well as free 1GB monthly usage on its mobile broadband, with the total costing as little as £308.08 over 18 months.

“The same deal with Orange, for example, would cost £528.48 and Virgin would charge £435.00, giving BT customers a saving of at least £125,” the spokesman said.

To get mobile, BT customers plug a USB modem into their laptop and in certain areas can get internet access at speeds of up to 7.2Mb over the HSDPA network.

The USB modem also works over the 3G network, which covers 80 per cent of the UK.

John Petter, managing director of BT’s Consumer division, said the “absolutely fantastic deal” for only 56p a day was “a no-brainer”.

As a rough guide, 1GB enables someone to send 300 emails, surf the web for 400 minutes, download one film, 48 photos, and 144 songs (BT says the data use examples are estimated, to give customers a rough idea of what they might get for their gigabytes and reminds them that applications which automatically download software – like Google Maps – will take up internet allowance too). Customers who need more than 1GB a month, can top up their usage.

BT Total Broadband customers also get membership of the BT FON network of 400,000 hotspots around the world, and WiFi minutes at BT Openzone hotspots across the UK and Ireland.

Customers will also benefit from BT’s rollout of hotspots at more than 650 Starbucks coffeehouses in the UK and Ireland.
