Short answer

Stop trying random fixes that could replace the last useful backup with an empty one. First, preserve the old phone or any visible chats, then check that you are using the same phone number or account and the same backup method the app used before.

Do not do these things

Do not uninstall and reinstall repeatedly just to see if it works.
Do not factory-reset the old phone while it may still contain readable chats.
Do not clear app data, delete backup files, delete iCloud or Google backups, or run cleanup tools until you have checked what exists.
Do not create a new backup over the top of an old one unless the app clearly explains what will happen.
Do not set up the same app on several phones or accounts at once while you are unsure which one holds the messages.
Do not give passcodes, verification codes, backup keys, screen-sharing access, or remote access to a third-party recovery service.
Do not assume support can recreate encrypted message content. Some apps do not keep a readable copy of your messages.

What to do now

Preserve the device that may still have the chats.
If the old phone still shows the messages, keep it charged and do not reset it. If you are worried the app may sync a blank state, leave the old phone offline for now, such as in airplane mode. Take screenshots of key conversations, backup dates, backup sizes, and the exact restore error.
Check the identity the app expects.
Confirm the phone number, app account, Apple Account, Google account, or other login is the same one used when the backup was made. A different number or cloud account can make a real backup look missing.
Check whether the backup exists without deleting anything.
On iPhone or iPad, check Settings, your name, iCloud, then iCloud Backup or iCloud storage backup screens. On Android, check the Google account or Google backup area used by that phone, and also check the app’s own backup screen if you can open it. If the app uses local backup files, look for the official backup folder before moving or deleting anything.
Look for app-specific restore blockers.
Make sure the phone has enough free storage, a stable connection, the correct account, the latest app version, and enough battery or charger power. If the app asks for an encrypted backup password, recovery key, or passphrase, do not guess repeatedly; find the saved key or passphrase first.
Use an old-phone transfer option if the app offers one.
If the old phone can still open the chats, check the official help page for that app for “transfer chats”, “move chats”, “transfer account”, or “restore from device”. This can be safer than repeatedly trying a cloud restore, but follow the app’s own order of steps.
Retry a restore only once, deliberately.
Close other apps, keep the phone awake and charging, and follow the official restore steps for that app. If it fails again, stop and write down the exact wording of the error, the point where it failed, the backup date shown, and the device model.
Contact the app’s official support with a short evidence bundle.
Include the device type, operating system version, app version, whether you changed phone or number, the backup date and size shown, and screenshots of the restore error. Ask: “How do I avoid overwriting an existing backup while troubleshooting?”

What can wait

You do not need to decide today that the messages are gone forever.
You do not need to reset the phone, change phones again, delete backups, or buy recovery software now.
You can postpone advanced steps such as clearing data, moving folders, or reinstalling until you know which backup exists and which account it belongs to.
A UK subject access request can wait. It may help you ask a company for personal data it holds about you, but it usually will not recreate encrypted message content or a missing local backup.

Important reassurance

This can happen after changing phones, changing numbers, using the wrong cloud account, losing an encrypted backup key, or relying on an app that stores messages only on your device. Slowing down and preserving what remains gives you the best chance of avoiding a worse loss.

Scope note

These are first steps only. Later recovery may depend on the specific app, the phone type, whether the old device still works, and whether the backup was cloud-based, local, or end-to-end encrypted.

Important note

This is general information, not legal, technical, financial, therapeutic, or professional advice. Backup and restore systems differ by app and device, and some services cannot recover message content if you do not have the required device, backup file, password, passphrase, or recovery key.
