I have been looking for a solution to have WiFi on the road with a low cost. I read about this software on RV net that uses my smartphone as a wireless modem. The data plan from Verizion is unlimited so I won't incur any additional charges while using my phone as a modem. I downloaded the software today and it worked perfect. The cost is low for the software and it has several versions for different phones. If you are interested, this is the web site:
