Do a little research with Verizon, they have the $10 per day, per line and a $100 per line monthly plan for international travel. Depending on how long you will be traveling in Europe the monthly plan may be more cost effective. We used the $10 plan when traveling last summer on the Rhine River and it worked great but we only were only there 9 days so it was a little less expensive to to the $10 plan. However our daughter is currently in Japan for 13 days so the monthly works better for her.
