iOS 9 'Wi-Fi Assist' Could Lead To Huge Wireless Bills
Dave Knott writes: One of the new features introduced in iOS9 is "Wi-Fi Assist." This enables your phone to automatically switch from Wi-Fi to a cellular connection when the Wi-Fi signal is poor. That's helpful if you're in the middle of watching a video or some other task on the internet that you don't want interrupted by spotty Wi-Fi service. Unfortunately, Wi-Fi Assist is enabled by default, which means that users may exceed their data cap without knowing it because their phone is silently switching their data connection from Wi-Fi to cellular.

That never happens without knowing it on Verizon. I get texts and emails when I reach 75%, 90%, 100% and then at each GB over the limit.
I have a teenage son. I get a lot of these notices.
I can see the fnords!
I find it useful to disable apps like Netflix from using the cellular network. Settings > Cellular, toggle it off.
