How to keep your cellular data use low! Since carriers are moving towards limited data plans we can complain all we want but we are still going to have to deal with it eventually or if your already interested in cutting back on monthly bills or don't need unlimited I thought I would start a "guide" towards mobile data usage and have people chip in with advice. I'm hoping some of you AT&T iPhone 4 users with the 250mb plan will crawl out of the wood work Anyways here is what I've devised and sort of partially put in practice just as a test run: -When I'm at a resturant, bar, coffee shop, etc. immediately turn wifi on and check for it and connect to it. Instant easy way to save. -I know facebook as instant mobile upload ability but think about it, your 10 minutes from home you don't NEED to upload that set of photos right now over cellular! Wait tell you get home to your wifi or alternatively hunt down some wifi nearby. As a former iPod touch user (2008) with only a dumbphone I am pretty skilled in the ability to hunt down wifi, beg people for passwords, etc . Yes its awkward asking your girlfriend/boyfriends dad the wifi password but just say you want to "watch something on youtube and need wifi". -Have your mail push less often. I have mine set to every hour instead of every 15 minutes. So far its worked for me. -Toggle cellular data under network settings if your nearing your quota or you don't need mobile data. (NOTE: This will prevent incoming and outgoing MMS messages) -Abstain from Youtube videos over cellular especially long ones. These eat data like crazy. ANyways I will edit and add more tomorrow! But chip in guys! Hopefully if this gets useful and large enough it can be stickied so we can avoid threads and help out the MR community!
