How to move your data to a new mobile without losing what matters

Upgrading to a new device is exciting, until you realise how much personal data lives on the old one. Photos, messages, authenticator apps, banking tools and offline files all need careful handling.

Modern iOS and Android tools make migration smoother than a few years ago, but there are still pitfalls. With a little preparation and the right order of steps, you can move to your new mobile with minimal stress.

Plan before you power on the new device

The most common mistake is turning on the new device and tapping through setup without a plan. Transfers usually work best when you start from a clean, factory reset state and follow the on-screen assistant closely.

Before touching the new device, check what you have on the old one: how much storage is used, where your data is stored (cloud or local), and which apps will need extra attention, such as banking, 2FA and messaging apps that tie data to a single device.

Back up your old device properly

A reliable backup is your safety net in case the direct transfer fails or you need to restore something later. On iOS, go to iCloud settings and confirm that iCloud Backup has run recently, or create a fresh backup over Wi-Fi while the device is on power.

On Android, use Google’s backup in system settings to save app data, call history, SMS (on many models), device settings and Wi-Fi passwords. Some manufacturers also offer their own backup tools, often with extra support for themes, home screen layouts and specific apps.

Sort out photos, videos and files

Media collections are usually the largest part of your storage, and they can slow transfers if you do not manage them first. If you use iCloud Photos or Google Photos, confirm that everything is fully synced and visible on another device or the web interface.

For local-only albums, move them to a cloud service or copy them to a computer or external drive. For documents and downloads, decide what needs to come along and what can be archived, then move important files into cloud storage or a dedicated file sync app.

Move SIM, eSIM and mobile number

Your number is a key part of many services, including messaging apps and sign-in codes. If you use a physical SIM, power off the old device, move the SIM carefully and insert it before starting the new device setup.

For eSIM, check your carrier’s instructions. Some providers support transferring an eSIM through a QR code or app, while others require reissuing the profile. Complete the eSIM move early, since some authentication apps and messaging tools depend on having an active number.

Use built-in transfer tools first

Both iOS and Android offer migration assistants that copy data directly from one device to another over cable or Wi-Fi. These tools usually transfer contacts, SMS, call logs, apps or app links, settings and media, and are the simplest path when both devices run the same platform.

When moving between platforms, use the official utilities provided by Apple, Google or major manufacturers. They normally handle basic data like contacts, calendars, media and some messages, but you should expect to reinstall apps and adjust settings manually.

Handle messaging apps and chat history

Messaging data can be tricky because different apps store chats in different ways. For SMS and basic messaging clients, the system backup or transfer assistant usually covers your history if you stay on the same platform.

For third-party chat apps, open their settings and check backup options. Some use cloud backups tied to your number, others store data locally. If you care about chat history, run a manual backup before migration and follow the developer’s guide for restoring on the new device.

Protect two-factor authentication and banking apps

Authenticator apps and banking tools often have strict security that binds them to a single device. Before wiping or selling the old device, move your two-factor codes. Many modern authenticators sync securely with your account so you can sign in on the new device and restore tokens.

If yours does not, use backup codes or transfer features offered by each site or app. For banking, log out on the old device only after you have successfully registered the new one. Some banks require a video call, branch visit or card reader, so plan time for this step.

Reconnect wearables and accessories

Smartwatches, fitness trackers and wireless earbuds usually stay linked to a single device. Unpair or reset them from the old one before you factory reset it, then pair them again with the new device through the relevant app or Bluetooth settings.

Pay special attention to wearables that store health data or offline playlists. Make sure that health metrics are synced to your cloud account and that any music or media on the accessory can be re-downloaded after pairing with the new device.

Check privacy and security settings on the new device

After the main transfer, take a few minutes to review security. Set a strong screen lock, register biometric unlock and enable features like Find My or similar device locator tools. Confirm that automatic backups are active from the first day.

Revisit app permissions, especially for location, microphone, camera and background activity. Transfers can bring over old permission choices that no longer match how you use the device, so this is a good time to clean them up and revoke anything you do not need anymore.

Only wipe the old device when you are sure

Keep the old device powered and connected for a day or two while you test the new setup. Make sure critical apps work, chats are present, and you can sign in to important services such as email, banking and work tools.

When you are confident nothing is missing, sign out of major accounts on the old device, remove any payment cards from wallet apps, unpair accessories, then perform a full factory reset. This protects your data if the old device is sold, recycled or passed to someone else.
