Work through the list in order. Hide the notes when you know what to do.

Call the phone and message it
Sometimes it is with the person at the next table or in a taxi. Start here; it takes a minute.
Locate it through the find-my-device service
From a computer or someone else's phone. The service shows the location and lets you play a sound and lock the device.
Turn on lost mode with a contact on screen
The device locks and whoever finds it sees where to call. This works more often than people expect.

Lost mode keeps the chance of getting the phone back, which a remote wipe removes.
Block the SIM with your operator
While the SIM is active, someone else receives your SMS codes and can call at your expense. This is the first security step.
Close access to banking apps
Through another device, online banking or the hotline. Tell the bank the phone is lost.
Change your email password first
Email is the key to every other account. After changing it, end all active sessions.

Email recovers every other service, which makes it the first target for whoever has your phone.
End sessions in messengers and social apps
Every service has a device list. Remove the lost one and check for unfamiliar entries.
Restore two-factor authentication
Backup codes, a second device or a support request. This is the slowest part; start it immediately.
Tell work if the phone held work access Work accounts and access
Email, chats, VPN, two-factor. The sooner you say, the sooner access is revoked — this is about security, not blame.
File a police report with the IMEI
Needed for insurance, sometimes for the operator, and in case the device is used for something illegal.
Check your insurance and what it covers
Sometimes the phone is covered by a card, bank or separate policy. Claim windows are usually short.
Wipe the device remotely if recovery is unlikely
After a wipe the location usually stops updating, so this is a last resort rather than a first step.
Restore your data from a backup
Check the backup is recent and restore it to the new device. You will also see what it was missing.
Get a replacement SIM with the same number
The number is tied to dozens of services, so keeping it matters more than speed. Ask the operator about the process and documents.
Check accounts for suspicious activity
Logins, transfers, sent messages, changed recovery settings. Especially in email and banking.
Set up protection for next time
Find-my-device on, backups running, backup codes stored separately, IMEI and a photo of the box saved.

Losing a phone is losing access first and hardware second

The device usually costs less than what is inside it: email, banking, messengers, photos, verification codes. So the first actions are not about finding the phone but about access: block the SIM, close banking apps, change the key passwords.

Order matters, because the SIM is a key to many services through SMS codes. While it is active in someone else’s hands, changing passwords helps little.

The first hour, in order

Step	Why this way
Call the phone	Sometimes it is simply on the next table
Locate it with the find-my-device service	Shows the location and lets you lock it
Turn on lost mode with a message	Locks it and leaves a contact for return
Block the SIM with your operator	Cuts off SMS codes and calls at your expense
Close access to banking	From another device or via the bank’s hotline
Change key account passwords	Email first: everything else is recovered through it

About remote wiping

Wiping is a last resort: afterwards the find-my-device service usually stops showing the location. If there is a chance of getting the phone back, use lost mode first. If it holds work data or access to other people’s systems, wipe immediately and tell your employer.

Police report and documents

A police report is not only about recovery: insurers and sometimes operators require it, and it protects you if the device is used for something illegal. You will need the IMEI — worth storing separately, along with a photo of the box or receipt.

Restoring access

Two-factor authentication tied only to the lost phone is the main difficulty. Backup codes, a second device or a hardware key solve it in advance. Without them, recovery through support takes days, so start immediately rather than “when there is time”.

So that next time is easier

Find-my-device switched on, backups running, two-factor backup codes stored somewhere safe, a list of important accounts and the IMEI written down. Fifteen minutes of setup that pays for itself once and completely.

When the situation is under control

The SIM is blocked, banking is closed, key passwords are changed, the device is in lost mode or wiped, the report is filed, two-factor is restored on a new device and your data is back from a backup.

Frequently asked questions

What should I do first if I lose my phone?

Call it, try the find-my-device service and switch on lost mode, then block the SIM with your operator and close access to banking. Password changes start with email: everything else is recovered through it.
