For the past 2 weeks we used a smart phone for data and voice with lime.

Spent $50 in a week on data and once we get home we will try and understand what we did wrong. Checking the weather shouldn't cost that much!

Our final decision is to just use a cheap phone for voice and use our Verizon iPad when on shore to check the weather via wifi. Wind guru does a great job and is pretty reliable so we just take screenshots for reference when we have no access to the Internet.
