Monthly data caps are the worst enemy of smartphone users. A small download at the wrong time can result in a high bill. Fortunately, you can use tools on your iPhone to monitor your data usage. Read on if you want to avoid a high bill!

To step

1. Open "Settings". You can find this app on your home screen.
2. Tap "Mobile data". You can find this in the top group of options.
   • In iOS 6, tap General → Usage → Cellular Network Information.
     
     
3. Scroll down to "Use mobile data". You can find the information about your usage here. The "Current Period" is not automatically set based on your billing cycle. So if you don't adjust that yourself first, the information you find here may be inaccurate.
4. Reset your data. Reset the statistics to that day in the month that your data cycle starts. Scroll down and tap "Reset data".
5. Check your subscription. The method we just discussed is very useful for monitoring your usage, but it doesn't say anything about your monthly limit. In addition, the data usage indicated by your iPhone sometimes does not fully correspond to what your provider has measured.
   • Go to your provider's website and log in with your username and password. You should be able to see how much you have used this month on your account page.
   • With most providers you can set that you will receive a warning SMS when your data usage is almost empty.
   • With many providers you can also request your remaining balance by text message or by calling a number. For example, for KPN users: text free "balance" to 1245. You will receive a free message with your remaining bundle credit and your usage outside the bundle. For T-Mobile: call 1202 for free.

Tips

• To calculate how much data you have used during a certain period, first tap on "Reset data", then you can keep an eye on how much you use from that point.
• This concerns mobile data traffic, not traffic over a WiFi network.
