Before anything else, make sure to align the usage cycle with your SpinTel billing cycle to capture actual usage within the period.
For Android (Samsung Galaxy S7)
Go to Settings and click on Data Usage
2. Click on Mobile Data Usage to find the amount of data used for each app.
For iPhone (iPhone iOS10)
1. Go to Settings and click on Cellular.
2. You'll see Cellular Data Usage and it will show the data consumed for the month. You may also scroll down to find which apps are using cellular data. If you don't want an app to use cellular data, you can turn it off for that app. When cellular data is off, apps will only use Wi-Fi for data.
"Current Period" data does not automatically reset for your billing cycle. You can reset your data usage statistics by tapping Reset Statistics at the bottom of the page.
