How much of my 4GB plan would that use? Our family plan is for 4GB, and most months we just barely hit 75% of our plan.
I love podcasts, but I had to figure out how to cut down on my data usage. There are two ways, force the podcast app to not download new episodes while on cell data, or try the app called "the network", which does the same thing by waiting until you're on wifi to check and download new episodes. Get in the habit of loading your new episodes before you leave for the day, after awhile it becomes second nature. Oh and as far as usage, you will eat through 4gb like nothing if you plan on doing the bulk of your podcast streaming while on your cellular network. I had to learn some new habits since AT&T had throttled my data 2 months in a row. I am on an unlimited plan, but they still have a right to throttle you for the current pay period if you exceed 10gb even on an unlimited plan.
