Unless you are streaming 4K video, your data should not run out that fast. What kind of phone are you running? On android, the OS contains lots of features to monitor and manage the data usage.
Yeah you should definitely take a look at what applications are sapping your data, both android and iPhone give you the option to look at what applications are using data. Let us know what you find out and best of luck!
I use mydata manager app it great.
also instead of buying 1gb for $30 you can always ask mods to renew your plan early. depends on what plan you have and how much time is left in your plan.
4-5 time addon purchase = $120-$150= 4-5 gb if on fall promo 12gb for $120.
do youhave wifi assist on iphone?
most phones will also show what apps have used data I woudl look at that aswell
@mimmo yes wi-fi assist is definitely a likely candidate. But could also be a process that's malfunctioning in the background and continually pulling down data over and over.
@Chri57ined is your battery also depleating quicker than normal/expected? Have you rebooted recently?
@Chri57ined what phone are you using? I think all phones have a way to see what apps are using the most data recently.
For example, on my OnePlus 3 (based on Android 7.1.1), if I go to Settings, Data Usage, then tap Cellular Data Usage, I see this, sorted in order of most data used so far this month:
Others have suggested Data Witness or My Data Manager, and those are great apps too, for tracking your overall progress through your 90 days worth of plan data. The built in data trackers don't align with your PM plan dates and durations, BUT, for something like this where you just need to know what app(s) are running away with all your data recently, they work well.
EDIT: Updated 2018-Apr-26. Steps are still the same on Android 8.1 (on my OnePlus 5T on OxygenOS 5.1.0). Here's my list of apps using the most usage since my [now Koodo] plan reset on April 12th:
@Rockdaddy22 @Luddite do you guys know of how to check on an iPhone to see what apps are using the most data? Similar to what I posted above on my Android phone? I'm 97.7774% sure the iPhone can give you the same info, but could you provide some guidance please? Thanks!
