How can I block ads from using my cel phone data plan? I'd like a way to block ads from using my cell phone data plan. I've reviewed this but it didn't cover my specific question. The upshot is that I have roughly 1000 times the data available on my wifi connection as I have with my cell phone providers data plan. I get that developers need to keep the lights on and do so by serving us ads, however I resent having my high-speed data from my cell phone provider used up in this manner and would prefer to only receive ads over my wifi connection. How can I accomplish this? I've tried ADP (ad blocker plus) but it only proxies out wifi which is the exact opposite of what I have in mind. I have a Samsung SGH-T399 (aka Samsung Galaxy Light) running Android 4.2.2 The device is not rooted but I'd be willing to try that in order to obtain the desired result.
You can turn off access to mobile data for all apps on the Samsung Galaxy 
Light by going to Settings->Connections->More Networks->Mobile networks and clearing the checkbox next to Mobile data This won't allow any data over the cell network, but data over wifi is still active. Note that this will likely have a negative impact on usability of a number of apps that require connectivity to operate as expected if you aren't connected via wifi, so you wmay want to flip it back on if your heading out.
