Excess data usage

[Kazzy33]

Is anyone else experiencing excess usage of data overnight. Every month im running out of data and i have 3gb. My average usage is 1.2. O2 say things are happening at around midnight but can't tell me what!!! I'm asleep then. Advice was turn off mobile data at home!!!  But why should I??  When I'm on WiFi it shouldn't use mobile data!!!! Any advice???

Midnight is when O2 update their systems so the entire days data use is rolled up and applied to your account then. It's not when it's being used.

Look in your phone settings to see which apps are using the most data and try to reduce that usage when not on wifi.

Hi @Kazzy33 data updates around midnight every day so depending on what you’ve used during the day it will be rounded up then. If you are using an iPhone then there is a known data issue on O2 with iPhones. Good advice to turn the mobile data off. Although if you’re WiFi cuts out or turned off then data will cut in. Look to see what apps are using the most data. It could be a rogue app you have  or Facebook is a known data hog

Settings >Mobile data and scroll down to see app usage since last reset.
At the bottom of the page you can reset everything to zero so you can track daily or weekly use etc.

Thanks but can't see anything that says app usage. But can see the reset option!!!

All your apps with usage should be listed on that page.

If you move the toggle you can stop those apps from using mobile data so they only work on wifi.
