Everyone who owns a cell phone can tell you that it one of the best inventions ever! Not only are we able to communicate on the go, but we can also enjoy portable entertainment. Well, turns out your cell phone could also be a life-saving tool.

Your phone is filled with many important contacts but the most important of them all is your In Case of Emergency (ICE) number. Since we password-protect our phones to protect our data from prying eyes, there's really no way for someone to access the ICE contact if something were to go wrong.

The solution? Add your ICE contact your phone's lock screen. This is will make it much simpler for someone to get in touch with your person in case you are incapable of doing so yourself. There are multiple ways of adding this info to your lock screen. You can either add the ICE through your phone's built-in feature, as a wallpaper or download an app that will automatically display it for you.

If you've got a phone that is capable of taking screenshots, write the ICE info in your 'notes' app then take a screenshot and use it as your lock screen wallpaper. This should work for most phones in the market including iPhones, Android and Windows Phones. You can provide as much or as little information as you want to.

If you prefer the app, then you can download from the App Store for $1.99 if you're an Apple user or from Google Play Store for Androids.
