Use Wi-Fi wherever possibleDuh. I mean, this isn’t 2003 when you had to explain what Wi-Fi was to a befuddled barista with a bad haircut. Today, Wi-Fi is available at most locations, including those that don’t smell of coffee or play “safe jazz”. Whenever you plan on sitting anywhere for a while, check for Wi-Fi and hook in. Your phone or tablet may even alert you to available Wi-Fi hotspots. That’s a major hint—a cry for help even. I’m certain every time my phone suggests a Wi-Fi connection it makes some Verizon executive somewhere weep.
Check mobile data usageDespite their desire to accumulate surcharges, mobile data carriers can be a source of help. Most of them offer an app or widget that lets you access their services, and one of those services is some sort of measure of your data usage. That app may display usage live or it may need to be refreshed, but it remains a handy way to see how close you are getting to the limit. Especially when you have multiple devices on a single plan, the mobile data usage widget is an invaluable tool.
You might also consider setting up your cellular provider’s data alerts: Visit their website to peruse available notification options. These alerts—free text messages or email—are sent to all devices on the same account, which is a bonus because teenagers actually read text messages.
Use the Data Usage tool to set data alertsYou’ll find the Data Usage tool lurking within the Settings app. It’s perhaps the best method for setting mobile data alerts and even disabling access when usage gets too high.
The Mobile Data item enables all data monitoring goodness for your phone or tablet. Once set, you can use the other two settings on the Data Usage screen to help curtail mobile data usage.
The item Limit Mobile Data Usage lets you set the ominous Red Bar of Doom on the usage grid. When mobile data encroaches upon its crimson glow, the device immediately stops using the mobile data network. The Red Bar of Doom can be adjusted up or down, depending on your data plan and whatever piddly data allotment your provider grants you.
Your cellular provider would like me to remind you that the information presented on the Data Usage screen is based on what your Android device has monitored. For corporate bottom-line reasons, that amount may not always be the same as usage values determined by your cellular provider. And, obviously, on plans with several devices, usage accumulates like dust bunnies under the couch.
Halt apps that use too much dataWhen you mosey on down the Data Usage screen you’ll discover those greedy that apps that vociferously consume mobile data. They’re listed in order of their appetite.
Incidentally, quite a few apps feature controls that limit their data consumption to Wi-Fi connections only. For example, Dropbox can be directed to sync photos only over a Wi-Fi connection. For non-critical data, such settings are like a can of Febreze next to the cat box.
Avoid using features that consume way too much dataWhat things can consume way too much data? Try tethering. Want to hog down all your monthly quota in an hour? Set up a Wi-Fi hotspot in an airport. These two features imperil your mobile data plan like a Costco-sized tiramisu endangers a Weight-Watchers convention. Don’t try tethering or create a mobile hotspot unless you have a mobile data plan beefy enough to support them.
Other data monsters include streaming music and videos. If you're going to do a lot of that, make sure you’re Wi-Fi connected. Otherwise, you’ll poke through your monthly data plan’s gigabyte threshold like Godzilla chewing through a Tokyo apartment complex. You wallet will appreciate that disastrous event not happening on a regular basis.
