Turn off background data on Galaxy S III? Wi-fi only for background data?
Lately, you’ve noticed you’re exceeding the data usage under your carrier’s plan, which is straining your budget. You suspect Google+™ is using more data than you’d prefer, so you open Data usage under your Settings menu, touch Set mobile data limit to disable the background data on the mobile data network only. Then select Google+ and touch Restrict background data. Now, Google+ will connect to Wi-Fi® for background data, but not your mobile carrier network.
