It’s a horrible feeling when you reach into your purse or pocket for your trusty smartphone and…it isn’t there. Here are the steps you should take when your device disappears.

Step 1: Try to locate it:

It seems obvious, but try it anyway. Be optimistic and ask someone nearby to call your phone since maybe it did just fall into a black hole at the bottom of your backpack. If no one is nearby, you can log on to wheresmycellphone.com and enter in your phone number. Of course those options are only helpful if your phone is powered on and not set to vibrate. If you’ve signed up for AT&T’s Mobile Protection Pack, you can use the Mobile Locate app to make your phone sound an alarm (whether the ring is on or off) and get its exact location on a map. But if none of these steps lead you to your smartphone…

Step 2: Lock and wipe:

Your smartphone knows a lot about you, so you want to clear its memory. Depending on the device you own, there are different methods of remotely locking your screen and wiping the data. Android owners can download the AndroidLost app, which lets you log in online to clear your phone and even add a pop-up message on the screen in case a Good Samaritan finds it. If you use a Windows device, no need for an app, you can just go to windowsphone.com and click My Phone to erase your data. Or check with your manufacturer to find out more about cleaning out your stored information.

Step 3: Change passwords

Even if the device is wiped, you still want to make sure to create new passwords for email or social networking accounts—like Twitter—that could be easily accessed through the smartphone.

Collect mobile insurance:

If you do own AT&T Mobile Insurance then making a claim is easy. Go online to phoneclaim.com/att and enter your account information and the make and model of your smartphone. Once the claim is approved, a replacement phone will be overnighted to you and arrive typically within 1-2 business days.

If you don’t have insurance:

Log into your account on AT&T and check to see if you are qualified for a phone upgrade. You can also browse through a large stock of refurbished phones.

Charges may apply for download of app. Messaging and data rates may apply for app download and usage.
