What to do when a phone with an eSIM is lost or stolen

First minutes: secure, do not improvise

Use another trusted device to open your phone-finding service and mark the missing handset as lost or secure it. Do not remove it from the service simply because a message says it has been found. Apple says Stolen Device Protection is designed to add biometric checks and, for some actions, a security delay when an iPhone is away from familiar locations. The feature must be enabled before the theft, so turn it on now rather than after an incident.

For supported Android devices, Google’s Find Hub can remotely find, secure, or erase a device when conditions such as power, connectivity, a signed-in Google Account, and Find Hub availability are met. The exact labels and features can differ by manufacturer and software version.

Protect the number and the master accounts

Contact the mobile provider through a number or app you already know is official. Ask it to suspend service or protect the number and account from unauthorised eSIM replacement, SIM swap, or porting. Follow the provider’s instructions; suspension and replacement rules differ by account and country.

Then protect the accounts that unlock the rest: primary email, Apple Account or Google Account, password manager, banking, and payment services. Change passwords from a trusted device if you think the phone was unlocked or your passcode may have been observed. Review recent sign-ins and remove unknown sessions. Do not rush to erase a phone until you have checked its location and understood the recovery trade-off; remote erase may be necessary, but it can end your ability to locate it depending on platform and state.

Preserve a clear record

Note the time, last known location, device model, IMEI if available from records, provider case number, and suspicious messages. Report theft to local police where appropriate, especially if an insurer or carrier requires a report. Never send your passcode, account password, QR code, or verification code to someone claiming to have found the phone.

Use the account-takeover response guide if service or sign-ins look wrong. Rebuild prevention with eSIM security basics and, once safe, follow the secure transfer checklist for your replacement device.
