How long will 100mb of data last on an iPhone?

How long would 100mb of data last on an iPhone if I'm just using twitter, Facebook and doing a little web browsing?

VERY fast. A 100MB plan isn't worth it.

150mb will allow you to check news daily with apps, sports, stocks, news, weather all that stuff. So 100mb I would think you would need to monitor very closely, of course you could use Wi-Fi much of that time then it doesn't matter.

  • Will 100mb of data be enough for a iphone 4s? The apps I would be using with data are just twitter and instagram. No emails, no streaming videos or anything and Wi-Fi would be used at home so would that be enough data for a month? I don't tweet a lot, just refresh twitter very often.
  • Is a 100MB or a 200MB data plan for an iPhone 4s better? I have Wi-Fi at home and I'm home about 70% of the time. I know I won't be using a lot of data, just some for Instagram, Tumblr, and Twitter when I'm not home. But I don't know how long 100MB will last me and how much/often I'd be able to use it when I'm not connected to Wi-Fi. So is 100MB good enough or should I go with 200MB?
  • Is 100mb iPhone 4s data plan enough? I'm looking into getting an iphone 4s and am wondering if 100mb of data is enough for me. I regularly check twitter and surf the internet. I would only go on youtube at home where this is wi-fi.
  • Is 100mb data enough for me? I'm getting an iPhone 5c and was just wondering if 100mb would be enough for me. Each day I would be using what's app, and bbm (although I've heard these use so little data that it doesn't even show) and also Facebook just to check my messages and notifications, snap chat, and the bus times app (only for about 2 minutes each day). Would this be enough?
