How many hours will 2GB of internet give me on my iPhone?

I'm going to be getting an iPhone 4S this Christmas and I'll have 2GB of Internet usage every month. I was wondering how many hours or days that I'd have on it. I'm a blogger/writer so I use Internet every chance I get. I don't watch videos, but I do watch vines and upload videos occasionally. How long would I have on the internet? Please and thank you.

Amount of data transferred is independent of time - short answer is it depends on what you're doing.

Using WiFi doesn't count towards data - use WiFi as much as possible.

Video - 1GB = 2 - 4 hours depending on quality of the video.

Websites that are mostly text use little data compared to video and picture websites.

Simple answer kimberly. Loads. Most people only receive 500mb
