| You may be able to use WiFi however it does depend on the availablity of hotspots which on arent easy to find, even if you do find one you will almost certainly have to pay, not sure about France but in the UK some places charge £5 an hour although the £10 a day is more reasonable.
Not sure how you think a TV signal digital or other wise will be helpful for anything other than watching TV, but if you have a TV tuner card (Analog and Digital) you should be able to watch TV on your laptop.
As for internet you then go to most people's backup which is GPRS via their phone which tends to be very expensive and not very fast, although most people if they want cheaper phone calls buy an international calling Sim or buy a sim for a local phone company, not no idea if they have data on them as well.
