Data plan is being used even when connected to a Wi-Fi network?

Ok I have an iPhone 5 with a 200 GB data plan. I don't understand how I'm going over my plan even when I'm connected to a Wi-Fi network, have cellular data off, close All apps in the back ground, and have current locations off. I switched from a blackberry torch 9800 and never had this problem. What should I do?

Why is everyone obsessed with Britain?

Lately I've noticed everyone had been obsessed with Britian.
My friends cry and get excited whenever someone mentions London. Like big whoop, it's NYC just a few hours ahead.
Everyone also walks around with stuff smothered with the British flag, like t shirts, shorts, iPhone cases, an bags.
I understand that the queen has had her diamond jubilee recently, there was a huge wedding, and the Olympics were there, but I don't really buy the Olympics thing or the wedding thing.
Like when they were in Canada or china, no one smothered themselves in Canadian or Chinese gear.
Also no one got all excited for Victoria of Sweden and Daniels wedding.
Why do people obsess over Britian, it's just a country, they're not any better than the rest of us. They're humans.

AT&T iPhone 4S receiving text messages late?

Today my iPhone has been receiving texts late. Like I will get a text at 6:20 but ill look at the time it was sent and it will say 6:15 or earlier. I've tried resetting my network and holding the power and home button for 10 seconds.
I'm also texting another person who is with AT&T and they said they're receiving texts just fine. My software is up to date.
Help?

Added (1). The closest Apple store is 2 hours away from me so I'd have to wait until next weekend to get it fixed.

Any other suggestions?
