over daya use

Hi

Firstly, which phone and which plan are you on?

The pause itself is Shock-Free Data doing its job — once you hit your plan's data limit it pauses so you don't go over your bill (you'd get a text at 50%, 90% and 100%). If you have authority on the account you can resume it by texting 5337 from your Koodo phone, or in Self Serve.

Koodo can't see what app is actually eating the data, but your phone might. On iPhone it's Settings > Cellular — take a screenshot of the per-app breakdown first, then Reset Statistics right when your next bill cycle starts so you can monitor it cleanly going forward. If you are using Android devices, you can check that similarly in data usage in settings

Are you enabling Background App Refresh on your phone? Did you allow cellular data usage to automatically update the apps and content? Have you enabled Wi-Fi Assist?

If you are not actively using an app on your device, you may want to look into disabling some of these features to prevent further usage.
