Late last year, Apple released an iOS 9 update which included a feature we're sure the company intended to help users enjoy the pleasures of the Internet better and more efficiently.
However, the same feature has one potential drawback that can have a nasty effect on your bill or prepaid credits.
Called "Wi-Fi Assist," it automatically switches you to 4G connectivity if it detects that your Wi-Fi is slow. The problem is, if it's enabled, you might not know that you're actually already using mobile data, resulting to unplanned prepaid load consumption and even a higher postpaid bill if you go beyond your plan's limit.
To make matters worse, it's activated by default once you get the update.
Now the good news: You can turn it off in three easy steps!
1) Go to Settings
2) Select Cellular or Mobile Data (naming scheme depends on where you are)
3) Scroll down and turn it off
That's it! Easy-peasy.
Now, if your bill is still giving you nightmares after doing these steps, well, better check your mobile surfing habits. No amount of Settings tinkering can do anything about that.
