If you have a Telus Peace of Mind plan and use an iPhone, it'll be easier to monitor your data use now. The iOS app has been updated to shows your data use, so you'll know when you've used up your high-speed data and are about to enter throttled speeds. Speeds are throttled to 512Kbps when you've exceeded your data limit. It's still usable for messaging and browsing emails, but you won't be able to stream video without interruptions.
