Is 2gb enough for the iPhone?

Hi I'm switching to verizon soon with my mom, and we're getting the shared plan that has 4gb, and my mom checks more her emails and barely uses the internet because she barely knows how to.
I use most of the social networking sites, like facebook, tumblr, instagram etc. I'll probably use less so my mom can have more gb for her emails?
But is 2gb each enough for both of us a month?
