Removing your SIM card is a simple step that's easy to forget but critical to privacy.

A factory reset wipes the phone's storage — skip it and personal data remains accessible.
Why This Matters Before the Phone Leaves Your Hands
Passing along an old phone — whether you're selling it, gifting it to a family member, or trading it in — feels simple. But a phone that hasn't been properly prepared carries real risks: saved passwords, payment methods, personal photos, and account access can all remain accessible to whoever picks it up next.
This checklist walks you through every step worth completing before your device changes hands. If you're simultaneously setting up a replacement, follow our data transfer guide to move your content over before you wipe the old phone.
Do Not Reset Before You Back Up
A factory reset permanently deletes everything stored on the device — photos, messages, app data, and saved passwords. There is no undo. Always confirm your backup is complete and accessible on another device before you initiate a reset.
What You'll Need
Before you start, gather the following tools. Most are already on your phone or in your home — nothing specialized is required.
Required
Cloud storage account (iCloud or Google Photos)
Used to back up photos, videos, and contacts before the device is wiped.
Required
SIM card removal tool or small paperclip
Used to eject the SIM tray so you can retrieve your SIM card.
Optional
Computer or external hard drive
Provides an additional backup destination for large photo libraries or local files.
Required
Original phone charger
Keeps the phone powered during the factory reset process to prevent interruptions.
The Full Pre-Handoff Checklist
Work through each group in order. The sequence matters: backing up before resetting, and signing out before wiping, prevents data loss and avoids locking the next owner out of the device.

Activation Lock Can Make a Phone Unusable
On iPhones, if you perform a factory reset without first signing out of your Apple ID and disabling Find My, Activation Lock remains active. The person receiving the phone will be unable to set it up without your Apple ID credentials. Always disable Find My before wiping — this step is required, not optional.
Once you've completed every step, power the phone off, package it with any original accessories if applicable, and hand it over with confidence. For a deeper look at security basics on a smartphone, see our beginner's guide to smartphone settings and security.
