I am a nurse and live in hospital accommodation and we have no phone line (don't even have a tv aerial in the wall). I have a new philips x50, which is great and i can use wireless net at my boyfriends and parents house easily. Is there any way i can get this without having a phone line-we are not allowed to have one put in either?please help-i feel very left out-even my nan has the internet at home!!

there are cables that will allow you to connect a cellphone to your computer. I imagine that directway (a satellite provider is out of the question)

you can get broadband via a small arial on your desk - no phoneline or cable needed check out http://www.mynow.co.uk/

You don't state what country you're in; that can make a difference. At least in the US, there may be laws in your state or community which prohibit landlords from prohibiting telephone installation, on the basis of safety. Laws in other places and countrys may vary. On the basis of personal safety, if nothing else, you should have a telephone available for emergencies.
Wireless broadband (not wi-fi) may also be available in your area for internet connections.
