1GB/month for my iPhone enough?

I've asked this question before, but I'm looking for more opinions. I'm planning to get 1GB of internet data for my iPhone per month; will it be enough or should I get less/more? At home I have Wi-Fi, so I'll do app downloading, video watching and all that at home. Otherwise, outside of home I'll be using it for Facebook, Kik Messenger, Snapchat, BBM, Whatsapp and probably random internet searching once in a while. I won't download apps out of home, nor will I watch videos because I know those chew up loads of data (from what I've heard).So is 1GB enough?
