At the end of June I will be headed to Cambridge (UK) for a conference. The conference lasts three days. However, I'll stay there for four days.
Is it possible to have a mobile (and preferably cheap!) Internet connection? I know that for instance in Finland you can buy a SIM card for 10€, and this gives you 7 days of (I guess limited) connection. Is there the same possibility up there in Cambridge?
In case there is not any of these possibilities, are there at least restaurants/cafes which offer you free WiFi? My hotel, unfortunately, doesn't.
Thank you so much for your suggestions!
