How much internet would I need in my plan with an Iphone 4s?

[YouDontKnowMe]

I will be using heaps of Facebook, and a little bit of google, some applications, but not lots of them.
So how much internet usage will I need?
Will 2 GB Be enough?
On Telstra in Australia, so it will be over-priced, but I live in a small town, and they are the only ones who properly service my location.

Yes that sounds like plenty for that.

2GB prolly will be okay but to be on the safe side, I say 4GB because AT&T's overage prices are crazy.. I'm sure you can't make it over 4GB in one month.. Unless you use your iPhone as a personal hotspot.
Hope this helped! =)

5gb

More than 2GB, i would suggest going with the maximum data plan. Because you are going to use the internet a lot but don't quite know the exact amount go with the maximum plan, going over every month will cost you boat loads more than paying for the most expensive plan.
