O2 have become the first Broadband provider to sell Home and Mobile Broadband together in one package. For £20 you get their 3GB Mobile Broadband package, including unlimited Wi-fi hotspot access with The Cloud, and they give you their entry level home broadband package free for one year. That saves you £7.50 per month.
It seems like a good deal if you live in an O2 Broadband area but want to get Mobile Broadband too. I’ve actually got O2 Home Broadband and it’s super-fast, running up to 19Mbps at my old house on the top package. Worth a butcher’s.
