Virgin Mobile and Virgin.net have teamed up on a free broadband offer to compete with the other mobile service providers' broadband services.

Customers who join the £15 or £30 SIM-only pay monthly service can sign up for a year’s free broadband with Virgin.net.

Those monthly services are on offer as well, as they same plans usually cost £20 and £32 respectively.

The broadband service normally costs £17.99 a month for 8Mbps download speed and a 6GB monthly download allowance.

The offer also includes free set-up and a free broadband modem.

Customers have 3 months to sign up for the offer after they’ve signed up for the SIM-only pay monthly tariff, but the free broadband deal only runs until 31 October.

There’s no fixed contract with Virgin Mobile SIM-only tariff, so as long as a customer continues to use the mobile phone service, they’ll get broadband free for 12 months.
