How much data is used on the iPhone 5 when just opening the Facebook app?
Best way to check that is to go to Settings-->General-->Usage-->Cellular Usage and you can see how much cellular network data u spent, good thing about it is that you can reset the numbers so you can track it however you want to: D. I'm not sure if 300mb is enough since I don't know how much time you are going to spend, and I don't use cellular unless I'm on a trip and can't find a wifi network. Hope I helped
