This would be negative if that was an option. I got a new laptop (best you can buy Surface Pro) and this app doesn't work on it. I spent almost 2 hours tracking down help on Verizon and they were useless, EXCEPT to sell me a $25/mo service plan that was also useless. Their website gives you the impression that the app will work on windows, but it does nothing but stimulate one to ask "what am I doing wrong?" BS
