Tracking mobile phone remotely with Internet
The following apps are widely used in Android and iOS devices to trace the location of a lost or stolen mobile phone.
Android device manager
Android device manager is a preinstalled mobile phone tracker app that comes with all Android smartphones. With the help of GPS, it can trace the location of the device and its last online status. We can remotely play sound, secure the device by safety lock, display a message or contact number and erase contents of the device.
To use an Android device manager, a device must:
- Be turned on
- Be signed in to your Google Account
- a data connection
- Have Location turned on
- Have Find My Device turned on (it is on by default)
- Be visible on Google Play (visible by default)
Follow the steps given below to access and control a device remotely
- Ensure you are logged in to your Google account
- Navigate to https://www.google.com/android/find
- Select your device from the list (if you have more than one device synced)
- You will be shown a few options to remotely access and control your device
Locate device: By choosing the locate device, Google maps will show you the last active location of the device.
Play sound: Device manager will make the device ring for 5 minutes, even if the device is set in silent mode.
Lock your phone: By choosing Lock, the device will be locked and a message along with a contact number you gave will be displayed.
Erase device: Google will erase all contents of phone memory. Memory card data will still be available. Once the erase is done, you cannot access or control your device remotely. Erasing should be considered only if all the other options of finding the device fails since you won’t be able to access the deleted data that wasn’t backed up to Google.
Find My iPhone
Apple devices are known for their strong security implementation. Jail-breaking an iPhone is impossible unless the version of iOS is vulnerable. Find my iPhone is a mobile tracker app used to remotely locate and access stolen and lost iOS devices such as iPhones, Mac computers, Apple Watch, and AirPods.
But you must have set up this option to remotely access your device.
How to set up Find My iPhone feature
- Start at your Home screen.
- Tap Settings > [your name] > iCloud. If you’re using iOS 10.2 or earlier, go to Settings > iCloud.
- Scroll to the bottom and tap Find My iPhone.
- Slide to turn on Find My iPhone and Send Last Location.
- If you’re asked to sign in, enter your Apple ID.
Find the approximate location of your iOS device, Apple Watch, AirPods, or Mac computer using Find My iPhone on iCloud.com. You can locate your device if:
- Find My iPhone is set up on the iOS device or Mac you want to locate.
- Apple Watch is paired with an iPhone.
- The iOS device, Apple Watch, or Mac is online.
- AirPods are out of their case and near one of your iOS devices. Any of your iOS devices can find the AirPods, but they must be paired with at least one of your iOS devices.
Tracking mobile phone remotely without Internet
Tracking a mobile phone is majorly dependent on data connection and its hard to track a device without internet connectivity. Interestingly, some apps find a device and even detect a SIM card change without the internet and alert the owner through SMS.
Android apps like Findlostphone, Wiperoid works based on SMS commands and helps the owner locate the device. When the desired command is sent to the mobile number through SMS, it responds with GPS location coordinates of the lost/stolen device. Anti-theft feature of findlostphone app detects a SIM change and alerts the owner number that was set up during the installation.
But you must have this app installed before you can control your device, otherwise, it is useless. In that situation, you have to go with OS default apps specified above.
Tracking a mobile number using IMEI / IMSI / MSISDN number
IMEI is an international mobile equipment manufacture identity that uniquely identifies a device.
IMSI is an international mobile subscriber identity that uniquely identifies a mobile subscriber (It identifies your SIM card).
MSISDN is a mobile station international subscriber directory number. It is your mobile number along with the international code.
Every mobile share all three numbers mentioned above whenever it connects to a cellular tower. Therefore only a tower (or the telecom operator) can track a mobile location.
So how can one track a cell phone having any of these IMEI / IMSI / MSISDN?
The legal way to track a phone
Obviously, the legal way to track a mobile phone is through telecom operators. You should have a court order in order to get information from the telecom operator. That is not possible in most countries when your device is stolen/lost since the process is complicated and time-consuming.
Telecom operators use the triangulation method to find the proximity of a device. The triangulation method uses three nearest towers to the signal of the phone to measure the nearest distance of that mobile phone and its location.
Illegal way to track a mobile phone
Stingray or IMSI catcher/tracker or cell-site simulators is a cellular phone surveillance device used illegally to track a phone. These devices are widely used by cops and law enforcement agencies around the world. Critics have called the use of the devices by government agencies warrantless cell phone tracking, as they have frequently been used without informing the court system or obtaining a warrant.
Stingray acts as a mobile phone tower in order to force all the mobiles to connect to it. Modern smartphones are still vulnerable to such kind of eavesdropping. Mobile phones believe that they are connecting to the legitimate cellular tower and routes all calls & messages to the IMSI catcher and thus enabling interception before reaching the actual tower. But the mobile needs to be in the proximity of a mile or so to enable tracking.
Such devices can be bought in online stores like Alibaba. Please bear in mind that this is an illegal device and must not be used to track anyone.
Lost cell phone?
It is easy to locate your smartphone as soon as you have lost your phone using the device manager but the mobile must be connected to the internet in order to access it remotely. If it is not connected to the internet, you can opt for erasing mobile memory. Device memory will be wiped once it connects to the internet.
SMS command based tracking apps is useful only if you have installed it prior to losing the device.
Regaining a lost device that is not connected to the internet is impossible and most countries don’t offer to track cell phones as a service whenever a complaint is registered since the process is complex. But making a complaint allows us to completely block the phone in the country, which means the mobile can’t be used. All cellular towers of the country would blacklist its IMEI number, even you can’t use it if you get back the mobile because of the blacklist.
