Whether you watch videos, listen to music, view photos, browse web pages, or navigate using your cell-phone, if you’re a Verizon Wireless customer starting tomorrow this could cost you more.  Following the lead of AT&T, which announced a similar change a few months ago, Verizon is capping data usage on their cellular plans.

When you go shopping for smart phone plans you’ll need to factor in more than voice minutes and texting, now you’re going to have to be a smart shopper when it comes to your data plan.

To give you an idea of what this means in terms of usage:

-200MB will get you 10 hours of sustained web browsing or 1 hour of streaming video.

-5GB will buy you 250 hours of sustained web browsing and 20 hours of streaming video.

-250 GB will buy you 50 million emails; 62,000 songs; 125 movies.

Verizon will ‘grandfather-in’ existing unlimited data users (as will AT&T), so be certain when you renew your contract or buy a new cellular device that if your plan had unlimited usage that this feature is rolled forward.
