In France we have a €19.99/mo plan with unlimited talk for domestic (land and mobile) and a huge selection of international countries (land), unlimited SMS/MMS, and 20Go of Data (yes, twenty). That plan can go down to €15.99/mo if you also go with this carrier for your home's broadband access.

That same carrier (called "Free mobile") offers a €2.00/mo plan for 2h talk, unlimited SMS/MMS and 50Mo data, which is €0/mo (free) if you're subscribed to their broadband.

And if the contract did not change, tethering is included. In addition with their ADSL offering you're allowed to host a server at home on your ADSL connection (which others did explicitly forbid when I chose Free over them a few years ago.)
