turned on the phone search feature
Most phones today have features that help you find them and remotely control them when lost. If you are using Android, you should turn on Google's Find My Device feature, while for iPhone, turn on Find My iPhone in Apple account settings. When your phone is lost, you can use a computer or other phone to locate the location, make the phone ring to make it easier to find, lock the phone or delete data to protect personal information.
Establish a strong password and biometric security
To protect data on the device, you need to set a password, PIN code or a highly complex lock, avoiding using simple passwords. At the same time, using biometric security features such as fingerprints and faces also helps increase protection against unauthorized access.
Periodic data backup
Regularly backing up data to cloud services such as Google Drive, iCloud or other storage platforms will help you easily restore information when your phone is lost. This not only protects data but also helps you quickly continue work without interruption.
turned off automatic connections and log in accounts
When you are not using your phone or suspect it is lost, you should turn off connections such as Bluetooth and Wi-Fi to avoid being taken advantage of by bad guys. At the same time, log out your Google, Facebook, and bank accounts on other devices as soon as possible to protect your personal information.
Beware of strange apps and messages
Do not download the application from unclear sources or click on links in strange messages, avoid data theft or install malware that takes control of the device.
Contact a network operator to lock SIM
As soon as your phone is lost, you need to contact the network operator to request the SIM lock, to avoid the situation where scammers take advantage of your phone number to commit fraud or cause financial losses.
