If you’re already using a new iPhone and just want to get all contacts without resetting your device, you can easily do it with iCloud:

1. Connect both your old and new iPhones to Wi-Fi.
2. Make sure you’re signed into the same Apple ID on both devices (Settings > [your name]).
3. On both iPhones, open Settings > [your name] > iCloud.
4. Enable the Contacts toggle on both devices.
5. Wait until the message about merging contacts appears and tap Merge.

Now, your contacts are synced between both iPhones. You can open the Contacts app on your new iPhone and pull down from the top of the screen to refresh the app. The contacts from your previous device will appear on the list.
