ONEWallet keeps your cards on your device rather than on our servers. That's the whole idea — but it also means a brand new phone starts out completely empty. Nothing follows you across on its own.
The fix takes about thirty seconds, and it has to happen before the old phone is wiped or traded in.
Turn backup on while you still have the old phone
Open Settings › Backup and sign in with your Google account. Once it's on, ONEWallet saves your card data every time you add or edit a card, so the backup stays current without you having to remember it.
Backup is opt-in on purpose. Until you switch it on, your cards have never left the handset.
Restore on the new phone
- Install ONEWallet from Google Play, Galaxy Store, or AppGallery.
- Open Settings › Backup and sign in with the same Google account.
- Restore. Your cards come back — numbers, codes, and the way you had them organized.
Do it before the trade-in. A wiped phone takes its cards with it.
What you'll still set up by hand
A few things belong to the phone rather than to your card list, so plan on a minute of tidying up:
- Home screen widgets — widgets live in the launcher, so put your most-scanned card back on the home screen once.
- The quick settings tile — pull down the notification shade and add the ONEWallet tile again.
- App lock — turn fingerprint or PIN protection back on in settings.
If you're not switching phones yet
Turn it on anyway. Phones get dropped, lost, and factory reset at inconvenient moments, and a wallet you've rebuilt by hand once is a wallet you'd rather not rebuild twice.
