How to Restore Signal Backup on a New Device

Switching to a new phone can be a pain, especially when you want to keep all your chats and media intact on Signal. If you’ve ever wondered how to restore Signal backup on a new device without losing your message history, you’re in the right place. I’ve been using Signal daily for years, and I’ll walk you through the entire process with some handy tips and tricks that helped me save hours of frustration.

Understanding Signal’s Backup System

First off, a quick heads-up: unlike many messaging apps, Signal doesn’t rely on cloud-based backups like Google Drive or iCloud. Instead, it uses an encrypted local backup file that you create manually on your old device. This approach prioritizes privacy and security, but it also means you need to be a bit proactive.

Signal’s official guide on signal.org covers the basics, but I’ll break down the steps and add some personal insights to make it easier.

Step-by-Step Guide: How to Restore Signal Backup on a New Device

1. Create a Signal Backup on Your Old Device

This part is crucial—Signal won’t back up your messages automatically, so you need to generate a backup file yourself.

Open Signal on your old phone.
Tap your profile icon (top-left corner) to open settings.
Go to Chats > Chat backups.
Toggle on Chat backups if it’s off.
Signal will generate a 30-digit passphrase—write this down carefully. You’ll need it to restore your backup!
Tap Turn on backups. This creates an encrypted backup file on your phone’s storage.

Pro tip: Don’t just screenshot the passphrase—write it down physically or save it somewhere safe offline. If you lose this, your backup is useless.

2. Locate the Backup File

Next, you’ll need to find the actual backup file Signal created.

On Android, the file is usually saved under Internal Storage/Signal/Backups.
Make sure you don’t delete or move this file accidentally.
Using a file manager app helps to verify it’s there before you switch devices.

Note: iOS devices don’t support local backups currently, so if you’re switching iPhones, unfortunately, you can’t restore chat history this way.

3. Transfer the Backup File to Your New Device

This is where things can get a bit fiddly.

Connect your old phone to a computer and copy the backup folder (the entire Signal folder or just the Backups folder) to your PC or Mac.
Then connect your new Android device and transfer the backup folder into the same directory: Internal Storage/Signal/Backups.
Make sure the backup file is in the correct folder before proceeding.

Heads up: Using cloud storage or messaging apps to transfer the backup file might corrupt it or expose it, so stick to USB transfer or SD cards if possible.

4. Install Signal on Your New Device and Restore

Install Signal from the Google Play Store on your new Android device but don’t open it yet.
Make sure the backup file is in place (as described above).
Open Signal, verify your phone number, and Signal should automatically detect the backup file.
When prompted, enter the 30-digit passphrase exactly as you saved it.
Wait for the restoration process to complete. It might take a few minutes depending on your backup size.

If you don’t get the restore prompt, try closing and reopening Signal. Sometimes it can be a bit glitchy.

Extra Tips from a Daily User

Backup regularly: It’s easy to forget, but I set a reminder every couple of weeks to create a fresh backup—especially if I’m sharing sensitive info.
Keep your phone charged: Backup and restore processes can drain battery, so plug your phone in during these steps.
Check storage permission: Signal needs permission to access your storage to create and read backups. If you run into errors, double-check app permissions.
Beware of losing media: Backups include messages and attachments, but if you’ve deleted media from your phone, it won’t magically reappear.
Don’t rush the restore: I’ve noticed if you try to restore multiple times or restart mid-way, it can mess things up. Patience pays off.

Wrapping It Up: What to Do If It Doesn’t Work

Sometimes the restore might fail or you might not see your chats after restoring. Before panicking, try these quick fixes:

Double-check that the backup file is in the right folder on your new device.
Make sure the passphrase is typed correctly — even one wrong digit breaks the decryption.
Restart your phone and try again.
Verify Signal app version is up to date.
If all else fails, consult Signal’s official support page for troubleshooting.

Switching phones doesn’t have to mean losing your Signal chat history. As long as you follow these steps and keep your 30-digit passphrase safe, restoring Signal backup on a new device is pretty straightforward. From my experience, the biggest hurdle is remembering to create that backup in the first place—so don’t make my mistake and wait until the last minute!
