Have you got a mobile with data allowance?
You could just turn your phone into a wifi hotspot and use that. I would suggest doing this as a trial to see if you can get good enough mobile reception to make it worth using mobile broadband.
If you have rubbish mobile reception in your new place (like we do) then using mobile broadband will be out of the question.
If for example you are on o2 for your mobile, you can get broadband for £3.50 (upto 20GB download/month) and phone line rental for £13 p/m, so £16.50 all in.
And if you don't like receiving calls on the home phone, just don't plug one in. Although if you have rubbish reception on your mobile then you'll want a landline for making and receiving calls. (We've changed networks from Orange-Voda-o2 and still not had good reception so have to have a landline - this, we didn't know before we moved into the house).
