Hi all I am using kinds of providers where the cellular data is quite restricted, but I personally do not watch any youtube or streaming videos and I don't play games at all. I primarily use my phone for web browsing, social networking and taking pictures as well. Is there any tips that I can do to keep my data usage low and restricted? Does apps running at the background cost a lot of traffic? Should I keep GPS (location) off as well? Is there any universal setting that I can keep all pictures / videos from social networking apps NOT downloaded unless I want them to? Any additional tips?
