What to Do When You Lose Your Smartphone


Phones get stolen or lost everyday. With a plethora of data ripe for identity-theft on it, a lost phone can easily make your blood run cold. Take a deep breath, How-To Geek will talk you through this.

It happened to me just last week. My iPhone 4 hadn’t left my sight in the year that I had it, but one tiny 5-second window of opportunity was all it took for a thief to snatch it up. Luckily for me, I was prepared enough to not worry about someone stealing my private information, but I knew I wasn’t seeing that phone ever again. If this happens to you, or you’re just prone to losing your phone, taking some precautionary steps will do you a world of good, but even if you weren’t entirely prepared, there may still be something you can do. Let’s look at the process step by step.

Step 1: Precautions to Take & First Resort Actions

Keeping Your Data Safe

I have a few friends who lose their phones a lot. A simple step you can take is to make your lock-screen wallpaper your contact information – like your name, work info, an alternate phone number, and email – so if an honest person finds your phone they know how to get it back to you. Depending on where you are, this may be more or less likely to happen, but it definitely won’t hurt as long as you don’t leave extremely sensitive information (like your home address) available for those without good intentions.

A little bit of precaution can go a long way towards safety, however. Android and iOS both have options for passcode-locking, and you can enable automatic wiping of your phone after several failed attempts. Even without this last option on, most thieves aren’t savvy enough to figure out how to bypass the locking mechanisms and access your data, so they’ll probably try to restore/reset your phone to factory defaults. This is a pretty solid measure you can take to prevent someone from getting into your phone and stealing data right away, but it also decreases the likelihood of you getting your phone back.

Locating Your iOS or Android Device

If you have a newer Apple device and you’re updated to iOS 4.2.1 or later, then you can use the Find My iPhone feature for free without a MobileMe subscription. Once you have it installed, you can log in online and see where your phone is via its GPS coordinates. GadgetTrak is a $3.99 solution that can take photos of your thief and email them back to you in addition to the Find My iPhone features.

Jailbroken iOS products have Cylay, which does the same stuff as Find My iPhone and GadgetTrak, but can utilize commands received by text message (which are cloaked and hidden from the thief). iGotYa originally made a lot of waves in the jailbreak community because it had two unique features: the ability to take and send pictures of the thief, and a “fake-out” mode. This latter mode allowed the thief access to the device so that they’d be less likely to wipe or restore it right away, thus giving you more time to track and find him or her. It’s a bit of a gamble, considering they may be able to get your personal information, but you can also combine this with other recovery methods if your paranoia gets the better of you later on.


Android users have tons of options, too. Wheres My Droid is a good option. You can text your phone with a pre-arranged code-word and it will automatically turn on the GPS and send its coordinates and/or start the ringtone at full volume (regardless of volume/silent settings). Lookout is an antivirus and security app that offers a similar functionality to Wheres My Droid. The premium version lets you wipe your phone remotely, too. Some people have replicated these functions using Tasker instead of using apps or services. Actually, I recently found out that many Motorola devices like the Atrix use a version of MotoBlur that has a built-in “remote wipe” command, so you may not even need an extra app if your manufacturer has added this to your phone.


The makers of Lookout also make another app called Plan B. The beauty of Plan B is that you can install it even after your phone is gone and it will send you tracking updates with GPS coordinates by email. It’s also free, so there’s no reason not to try it.

Lastly, there are services you can use. StuffBak (now ReturnMe) offers a way for someone who found your lost device to send it back to you safely and without a cost to them. You can even include a reward for the other person to sweeten the deal for them. Prey is an open-source project for Android phones and computers that will keep track of them for you, send you a picture of your thief, delete sensitive data, and more. There’s Linux compatibility, too, in case you run Ubuntu or Debian on your laptop. It’s definitely a great service and has a free option that works pretty well. Pro plans start at $5 a month (for up to 3 devices) and give you more features, like SSL encryption, and “Active” mode, and more reports per device.

These options give you a wide-range of flexibility in trying to locate and secure your lost or stolen phone. If you really need your phone back, though, you should hold off on wiping your data for now, as there are still things you can do.

Step 2: Round-about Methods

If you didn’t take proper preventative measures, you might be able to figure out how to locate or access your device in a different way. Latitude on both Android and iOS can be configured to update your location in the background, something you can lookup online. You can also log in to your carrier’s website and see if your thief made any phone calls or sent text messages to weird numbers. You can then record this as proof for the police if you ever find the perpetrator but get stuck in a “his-word-against yours” situation. If that happens, knowing your device’s IMEI/ESN/Serial number will also be very handy, all of which can be found on your device’s box.

Gmail and some other online services record a list of IP addresses used to access your account. You may be able to use this to access your phone via another means, like SSH, and you can grab important data and/or wipe your phone clean that way. I was lucky enough to do this, though I had a DDNS client on my iPhone for a project I was working on, so that made finding my IP address much easier. If you sit and think about what kinds of services you have running and how you can track them from the web, you might be surprised to find out how easy it is to track your phone down.

Step 3: Damage Control

Legally speaking, if all you have is an IP address, there’s not much you can do to get your phone back. It normally takes time and more proof to get a subpoena for the IP from the ISP, and even then, there’s no guarantee that you’ll be able to nab your thief. To make matters worse, he or she probably will have sold your phone by then even if you can establish proof. Having a picture emailed to you and having records from your carrier’s website can really help speed up the process, but it may not be enough.

Phone thieves are usually clever enough to shut your phone off and switch out the SIM card before trying to use it again, which negates many of the protective measures we’ve discussed so far. If you have the ability to wipe your data and there’s no way to recover your phone, now is the time to do it.

If there is any doubt at all about your personal data, you should go ahead and change your passwords immediately. In fact, you should do it anyway because, hey, you never know. Change all passwords to any service that is connected to your phone automatically, like Gmail, PayPal, and your online banking account. Deny access to your device by services like Facebook, Twitter, etc. Lastly, once you have determined that your phone is definitely gone, you should report your phone as lost or stolen to your carrier so you can avoid being responsible for any charges that were racked up.

Verizon flags lost or stolen phones with “bad” ESNs, so they can’t be activated on their network again, though other carriers don’t necessarily do this (AT&T definitely doesn’t). You should also get a police report completed with your device’s serial number if you have insurance. Even if you don’t, it’s not a bad thing to do just in case something else comes up.

Step 4: Replacing Your Phone

Lastly, you’ll need to replace your device. Many carriers offer insurance on their devices, so if you have a police report and pay a deductible, you can get a replacement. I’ve also heard anecdotal stories of people getting discounts at Apple stores with sob stories and the like, but it hasn’t happened to me. When you report your phone as lost or stolen, your number is suspended so no one can use it. You’re still charged for it, though, per the contract you signed. If you walk-in to your carrier’s store, you might be surprised to find that you have an upgrade waiting for you. Some carriers allow partial discounts for upgrades due to customer loyalty or “annual” discounts, despite you still being on contract. You can also talk to a sales rep and see if you can “borrow” a family member’s upgrade option if you’re on a family plan.


Phones off-contract are not cheap in the slightest, but be wary of buying used ones online. Many lost and stolen phones end up here, and there’s usually no guarantee that the phone you paid for will work (see previous section about Verizon flagging “bad” ESNs). Often, if you put out notice in your social circle that you need an older phone, someone will notice they have one laying around that you can use. It may not be the same as your awesome phone, but it’ll get you by until the next upgrade.


Losing your phone is tough, but we hope you’ll take the proper precautions to keep your data safe and possibly get your phone back easily. If not, it’s good to know that you have options and what steps you need to take to safeguard your personal accounts.

    If you have your complete make, model and serial number, another reason to make a police report is that it can be entered into a national database as a stolen item. Many places have mandatory reporting for pawned items which are all checked against the database. And if your perp encounters an officer who has reason to suspect the phone is stolen, the officer will check it by serial number to see if it is listed as stolen. It’s rare, but I have seen people get their stuff back this way. Also, anything with a unique serial number can be entered this way, so its a good idea to record the serial numbers of anything you have that is a likely theft target (laptops, flat screen tvs etc).

    You don’t even have to have it installed if you want to utilize it. Just push it to your phone & lock it down/wipe it/locate it/etc..

    Hi guys!
    Tell me please, when will you change the name of company on correct – HTC (NOT HTG!!!)?

  4. bb

    HTG = How To Geek…

    I’d have liked to see a paragraph on Windows Phone as well- of course, that would be pretty short:

    Log in to Skydrive, click Find Your Phone. Look on Map. Click Lock Your Phone, add message to return it with phone number.

    Actually, I discovered that Lookout for Android still can utilize some(if not all) of the functions it has EVEN when the SIM is yanked. Dont believe me? check their website.

  7. Br@ts

    Its all for iPhone and Android Smartphone devices!
    but what about Nokia Symbian devices! :(
    in last year I made a tour to a website which offered these services for Nokia also! But now I have forgotten the website address!

    HTG is How-to-Geek…..

    My daughter’s iPhone (my old 3gs) was stolen while she was at the high school. She had a password on it and I had installed the Find My iPhone app earlier. We tracked her phone to a rival high school’s parking lot a couple of towns over. Our school’s girl’s soccer team was playing them at the time coincidentally. But locating it in a parking lot is a little tough. Then it started moving. It went back and forth between a few blocks. I honestly didn’t know what I’d say if I found someone walking around.

    Then the last signal we got was in an alley. We live in Chicago, so that blue dot was pretty precise! We checked trash bins and all over. I saw a few people who looked at me funny as I dug around in the garbage. I just asked if they’d seen a phone around, that we had lost one.

    We sent a nice message (phone lost! $100 reward. Call or text xxx-xxxx. No questions asked!) Then a more nasty one (We know you’re at the corner of blank and blank. Give us the phone! Pretend you found it and get a reward! xxx-xxxx) But then a few minutes later it went off line.

    So… long story short, we didn’t get the phone but we got a good adrenaline rush chasing it around feeling like spies and sending the people messages. I wish I had heard about the photo-taking app beforehand. The police told us not to track it down, but looking at that dot blinking and online on my map was too irresistible! I had to try a little!

    @Artur HTG means How to Geek not HTC like the phone company. Please think about what something might mean before you post about it.

    When setting up “Find My iPhone” you will, indeed, be given a MobileMe registration which will be free. Except the stupid Apple store will charge $.00 to your credit card, which will trigger a fraud hold on your credit card. Ask me how I know … ~~~>:-(

    learn to spell morans!

    This is the time to press the FCC to act. Every phone provider sees the unique identifier of every phone every time it is used. That’s how they know if you paid you bill, are roaming etc. It would be trivial for them to identify a stolen phone, even with another SIM card. They could block it, locate it, call the cops.
    No-one else has immediate access to each phone. They refuse to do it because is is too expensive. Right!
    Moreover, once crooks learn that stolen phones are useless, they’ll have to learn to steal something else.

  14. babal

    TheftAware is better. It’ll be there even if the thief does a factory reset.

  15. Max

    Bob ironically posted, “learn to spell morans!”

    Bob, it is spelled “morons”, just so you know for future reference. Thanks!

  16. Lauren

    Max – I think that Bob was trying to be ironic.

    Any tips/apps/etc. for BlackBerry users?

  19. Hasitha

    HTG reader from Sri Lanka,
    These tips only valid for high end smart phones, but here in sri lanka we don’t need to install apps or anything to recover our phones. Police & TRC have a system that can track all mobile devices in sri lanka, no matter it’s an iphone, android, entry level Nokia or chinese phone. also IMEI is optional (only added value) for police inquiry. Only they need is your Phone number & Phone Model.

    Knock on wood, I’ve never lost my phone EXCEPT in my own hacienda. When that happens, I bring up Google phone and call myself. Since I’m retired, I don’t use a smart phone, just a cheap Virgin phone for which I pay $33 a month, including sales tax. My laptop is all I need now, that plus my Kindle and Color Nook, that is.

  21. Michael Todd

    If you have a Windows Phone 7 (like I do) then is where to go. You can ring your phone (even if its on silent mode) lock it out, change the screen saver to your email or a notice of reward, locate your phone via gps, or, if worse comes to worse, wipe it clean.
