How long will 2gb of data last on an iPhone 5s?

I use the Internet on my phone quite a lot for twitter and things so how long will it last me do you think? Is it a lot?

If you don't download too much music or videos it should last a month.

Will last a lot longer if you make sure to connect to a wifi when available for using the internet and also only update your apps on a wifi connection. That should make your data plan go further for you.
