Data usage different in Verizon phone settings & website. Which one is correct??

[AC Question]

Data usage in the settings on my phone says I've used .47 GB in 2 weeks. But on the Verizon web site it says I've used .22 GB. Which one is correct??

Probably the site - and it's normally the other way around, they say you've used more than your phone says you have.
