1 Set data usage alerts and Limits. You can check your data usage by going to Settings>wireless & Networks> data usage.You can tap to tick the Set mobile data limit box and then move the orange and red lines to set an alert usage amount (so you’ll get a warning when you’re closing in on your limit), and a hard limit (which will prevent you from going over your allowance).
You’ll also find that most carriers have an app that will allow you to keep tabs on your data usage and allowance. For example, My Verizon Mobile and myAT&T (both are available for Android as well) let you keep track of your data usage.My Data Manager (Android, iOS) is a free and easy-to-use app to keep track of your data and set alerts up.
2 Try to Use free Wi-fi service where ever possible.Make sure you get into the habit of doing it and you can make huge savings on the data you’re using. It’s as simple as tapping Wi-Fi in your Settings menu. Access it on a newer phone by pulling down your notification tray with two fingers instead of one, then tap the Settings button.
3 Limit background data.One of the main drains on your data is probably going to be background syncing, when an app like Facebook grabs an update, or your phone checks to see if there’s any new email on your server.
4 By changing your browser you should only browse mobile versions of websites where possible, as they tend to be simpler versions that will load faster and use less data. You might also consider using a browser like Opera Mini (Android, iOS) as it’s designed to compress data and dramatically reduce your usage when browsing. There are also options, like TextOnly Browser on Android, that strip out all the images and just serve up the text, which is also a major data saving.
Cache or preload data
5 Compress your data.Check out the Onavo Extend app (Android, iOS). It is designed to compress your data and potentially extend your data plan by up to five times. It doesn’t work with streaming audio or video apps, and it doesn’t work with VoIP apps, but it will help reduce the impact of images and text. It gives you a breakdown of which apps are using your data, lets you create a universal cache, and helps you choose the balance you want between image quality and data savings. It’s free, so it’s worth giving it a try if you find yourself running out of data all the time.
6 Find the right plan for you: Carefully review how often and in what ways you use your phone.
