How much internet data does the average person use?

Me and my Dad have a caravan at the seaside but we don't have internet access in the caravan (apart from our smartphones).

I have an iPhone on contract with 10gb per month data allowance, and I've just found out that I can use my iPhone to create a personal wi-fi hotspot. I was going to do that so I can use the internet on my laptop at the caravan, but will I be in any danger of using all my data allowance if I do this every weekend?

IPhones earphones one of them not working?

I just got my new iPhone 5s along with the earphones they come along with almost 2 months ago. I love the earphones, but just yesterday one of them went out. I can't hear from it, I'm guessing it has something to do with the speaker, can I go back to at&t where I first got it & ask for another one because 1 month & a half is way to short of a time for me to have problems with the earphones.

Is Cricket Wireless for poor people?

To me, it is.

I mean, their phones are all bulky and have a cheap plastic feeling.

I even heard someone say it's for smart people, since why pay more for the "same" service. LOL.

I'm quiet happy with my iPhone on AT&T.

Cricket is also for ghetto people.

Storage Help on my iPhone 5?

Storage has always been a problem for me with my 16 GB iPhone 5. Today, I went under usage and added up what it said every app had stored memory wise (ex. Music 3GB), but it only added up to 5.6 GB. My phone claims it is using 12.4 GB of storage. I have iOS 7.0.4 (Not sure if that makes a difference) and have had this phone for a little over a year.
