How to Check Data Usage on an iPhone

Monthly data limits are every smartphone user's enemy. A small download at the wrong time may send your bill skyrocketing. Your iPhone has built-in tools that allow you to track your data usage, but you can also get free reports from your carrier that give you a more accurate picture. See Step 1 below to learn how.

Step:-

1. Open Settings. You can find this app on your Home screen.

2. Tap Cellular. This is located in the top group of options.

• In iOS 6, tap General → Usage → Cellular Usage.

3. Scroll down to "Cellular Data Usage".

Your usage information will be listed. The "Current Period" does not automatically reset for your billing cycle. This means that if you do not reset it yourself, the information here may be very inaccurate.

4. Reset your data usage statistics.

In order to get the most accurate readings from the iPhone, reset the statistics on the first day of every billing cycle. You can reset them by scrolling to the bottom of the screen and tapping the Reset button.

5. Check your data plan.

While checking the data usage in your Settings will show you how much you've used, it won't show you what your limit is, and sometimes the date and measurement is off compared to your carrier. You can quickly check how close you are to your monthly limit by entering the code for your carrier:

• Verizon - Dial #DATA and press Send. You will receive a text message showing all your usage details for that billing cycle. If you have the My Verizon app installed, the app will open and you can see your current data usage versus your monthly limit.
• AT&T - Dial *DATA# and press Send. You will receive a text message showing how much data you've used versus your monthly limit. You can also download the My AT&T app to check your data usage.
• T-Mobile - Dial #WEB# and press Send. You will receive a text message showing how much data you've used versus your monthly limit.
• Sprint - Dial *4 and press Send. Follow the voice prompts to check your usage for the billing period.
• Rogers - Visit the Rogers website and log into your account on your iPhone's web browser, or download the Rogers My Account app from the iTunes store.
• TELUS - Visit the TELUS website and log into your account on your iPhone's web browser, or download the TELUS My Account app from the iTunes store.
• Vodafone (AU) - Send a blank text to 1512. You will receive a reply with your usage.
• Vodafone (UK) - Download the My Vodafone app from the iTunes store. You will be able to check your data usage through the app.

Tips:-

• Cellular Usage is wireless data you’ve used for web browsing, email and more that was provided by your carrier and not a Wi-Fi network.
• To calculate how much data you use over a period of time, tap the Reset Statistics button and then check the data you have used from that point onward at a specified time.
• Tether Data is data used while your iPhone has been connected to another device using the Personal Hotspot feature.
