Hello all I don't know whether this has been covered but the telecoms supplier '3' in the UK now allows UK PHONE and DONGLE contracts to be used worldwide with no Roaming or additional charges!
I have been using a '3' Dongle here in the Mountain Noir Haut Langqedoc for a month now phone for £8 month (1 gig) and a phone for £15 per month. You can also do Pay As You Go.
For those of us who flit between the two countries ( the deal also covers most of Europe the US and Australia) they are an amazing deal.
Have a look at the website
