Using eSIM
Phone with eSIM lost or stolen: act immediately
Lost a phone with eSIM? Follow the right order to secure the device, accounts and mobile line, then arrange a replacement eSIM safely after loss abroad.
In this guide
If you lose a phone with an eSIM, first use Apple Find My or Google Find Hub to put the device in Lost Mode or secure it. Then ask your provider to block the mobile line, inspect important accounts and erase the phone remotely only when recovery is unlikely. Keep the device in your finding account while Activation Lock is still needed.
Do this from a trusted second device. On a borrowed computer, use a private window, sign out afterwards, and retain the order number, IMEI and provider contact details as evidence for blocking and replacement.
The first 15 minutes: follow this order
- Call your phone without leaving sensitive information in a message.
- Open the official device-finding service through your own bookmark.
- Mark the device as lost or secure it with a lock.
- Display an alternative contact number on the screen.
- Record the last location and time; do not enter an unsafe place yourself.
- Contact the provider and ask it to block the line.
- Check email, banking and primary accounts for unfamiliar activity.
Apple advises marking a stolen iPhone as lost promptly and asking the carrier to suspend the account. See Apple's steps for a stolen iPhone.
Lost Mode, line blocking and erasure compared
| Action | What does it protect? | Is it reversible? |
|---|---|---|
| Lost or secure mode | Screen and access to the device | Usually |
| Provider blocks the line | Mobile service and possibly the number | Provider can arrange recovery |
| Change account passwords | Online accounts | Yes, with the new credentials |
| Remote erasure | Local device data | No |
| Remove device from finding account | May remove Activation Lock | Risky before recovery |
A provider block and a device lock complement each other. Disabling only the eSIM does not protect every app and file on the phone.
iPhone with eSIM lost or stolen
Go to iCloud.com/find or use Find My on another Apple device. Mark the iPhone as lost. Apple warns that it will not contact you to say the device has been found, so do not open an unexpected Find My link in an SMS or email.
Erase the phone remotely only after trying other recovery options. Do not remove the iPhone from Find My: Apple explains that doing so may disable Activation Lock and make resale easier.
What happens to the eSIM after erasure?
During a local reset, iPhone may ask whether to retain or remove the eSIM. If the eSIM is erased, you need to contact the carrier to reactivate mobile service, according to Apple's reset instructions. After theft, the provider should assess and block the line at account level in every case.
Android phone with eSIM lost or stolen
Use the official Google feature to locate, secure or erase the device. Google also advises signing the lost device out of active account sessions if recovery is unsuccessful. See how to find, secure or erase a lost device.
The available actions require the phone to be linked to the correct Google Account and to come online. If the device is offline, a command may not run until its next connection.
Which passwords should you change first?
Start with the primary email account because it often controls password recovery for other services. Continue with the provider account, bank, password manager and social accounts. Do not change everything at random on an unsecured public device; use a trusted device and inspect active sessions.
Have the eSIM or mobile line blocked
Contact the provider through its official number or portal and report the loss or theft. Ask it to block the profile, the line and, where appropriate, the device identifier. A data-only travel eSIM may not have a phone number, but its remaining allowance and account access still need protection.
Have the following details ready:
- order or customer number;
- email address used for the order;
- ICCID, if stored outside the phone;
- IMEI or serial number;
- date, time and country of loss;
- last known error or usage notifications.
Arrange a replacement eSIM on a new phone
Do not assume that the old QR code will work again. The provider may support a transfer, issue a replacement activation code or require a new package. Install it only on a phone that you have secured with your own accounts.
Follow transfer an eSIM to a new phone and read use one eSIM on multiple phones to understand the difference between moving and copying.
Recognising fraud and phishing after theft
Thieves can use contact details on the lock screen to send a convincing phishing message. Do not open a link that asks for your Apple, Google or provider password to recover the device. Navigate to the official account yourself.
Check unfamiliar recovery numbers, email addresses, trusted devices and payment transactions. Read is an eSIM secure? for SIM-swap and account precautions.

Frequently asked questions
Can someone use my eSIM if my phone is stolen?
The risk is greatest when the phone is unlocked or its accounts are poorly protected. Put the device in Lost Mode immediately and have the provider block the line. An eSIM cannot simply be removed, but the active phone and its apps remain valuable targets.
Should I erase my lost phone remotely straight away?
Not always. Lock and locate it first because erasure cannot be reversed and may affect finding it. Erase the phone when recovery is unlikely and sensitive data is at risk. Keep a stolen iPhone in Find My so that Activation Lock remains enabled.
Will my old QR code work on a replacement phone?
Often not. Many activation codes work only once, and the profile may still be linked to the lost phone. Ask the provider to block it and supply an official replacement or transfer route. Do not remove items from accounts until support has confirmed the required steps.
Can my eSIM provider locate my phone?
A provider can generally block the mobile line but does not offer consumers a live-location map. Use Apple Find My or Google's device-finding feature if it was enabled beforehand. Share a theft location with police; do not travel to a potentially unsafe place yourself.
Which details do I need for the police or insurance company?
Requirements vary, but a serial number or IMEI, proof of purchase, time and place of loss, and a police report number are often requested. Store these details outside the phone in advance. Never include passwords, recovery codes or the full eSIM QR code in an ordinary report attachment.
