We received out Raileurope ekit today which will allow us to use our laptop while traveling around Europe.  The kit includes a Huawei E160 USB modem witch is for data only and a SIM card loaded with $20 of data which is about 50 MB of service, which can be renewed via internet or phone.  Additional MB at $.39/MB.

You can also add a Free USA number, of course you will have to purchase time for the card. Visit http://www.rechargeminutes.com
