Top 5 most common data horror stories

This post is a part of an ongoing series about mobile data usage.
During October, we hosted a Data Horror Stories Contest, where thousands of individuals who have previously been burned by their data plans submitted their tales of mobile-data-overage woes.
Within those submissions, we started to see some recurring complaints about how users went over their monthly data plan limit. Below is a rundown of the most common.
Forgetting to use Wi-Fi
Have you ever turned your Wi-Fi off and realized later that you’re still using mobile data even though you’re sitting at home, 2 feet from your router? Or gone to a bar only to realize at the end of the night they had free Wi-Fi? Don’t worry, it’s happened to a lot of us.
#DataHorrorStories #OperaMax Streamed a football game at a public place with wifi. Have limited data plan. Forgot to use the free wifi.

Streaming from music & video apps
We all know how easy it is to get lost in a music video or zone out listening to Pandora on the way to work. The problem is that apps utilizing video & music tend to eat up a lot of data, and fast!

Traveling abroad
Sure it’s fun seeing the Eiffel Tour or the Leaning Tower of Pisa, but you know what’s not fun? A $200 roaming bill.
Went to France last year. My phone bill when I got back home cost more than my hotel in Paris #datahorrorstories #operamax

#datahorrorstories I went to China for a great vacation. When I came back, I realized that 50mb of data equals about $100. 🙁

Auto-updates
Whether it’s auto-updating apps or automatic backup of emails, pictures, etc., these automatic events that happen in the background, often without a user’s knowledge, can rip through data plans.
The awkward moment when you hear a "backup finished" notification with 4G just after filming on your phone #datahorrorstories #operamax

Shared data plans
You may love your sister/brother/cousin/girlfriend, but you don’t have to love how much data they use from your “shared” plan.
@opera #DataHorrorStories Realizing my girlfriend is somehow capable of using 16gb of data per month… #opera

Its difficult trying to explain to the person who pays the bill how 3GB of data vanished in less than 24hrs. #DataHorrorStories #OperaMax
