It’s happened to me once or twice before, I tether my phone to my computer and the next thing I know I’m paying $50.00 in overage charges on my next bill.
Checking some emails while on the road shouldn’t cost me a small fortune. But, when a bunch of apps and services begin falling over one another to reach the web and begin downloading and updating files, I know I’m in trouble.
It usually happens quicker than I realize, and every single time it eats into my data plan.
David Sparks just posted a link to a tutorial that solves the problem using Little Snitch. The app helps keep your overage costs down while tethering your phone on an LTE network by blocking access to certain services when you tether.
Long story, short: set up a couple network locations and narrow in on what services you want to block while in those particular situations.
It’s pretty genius. I’ve used Little Snitch in the past, but never to the extent demonstrated in the tutorials. It’s worth reading, and then reinstalling Little Snitch.
