If your phone is stolen, you must act quickly: block your SIM card, lock or wipe the device using official tracking tools, and sign out of your accounts from another trusted device.
Step-by-step emergency protocol:
- Wipe the device remotely: Use Google's 'Find My Device' or Apple's 'Find My' to lock or factory reset your phone from a distance.
- Block your SIM card and IMEI: Call your mobile carrier immediately to prevent them from using your number to receive SMS authentication codes.
- Sign out and change passwords: Access your bank accounts, email, and social media from a computer to unlink the stolen device.
