How to Migrate from iMessage to Signal

Switching from iMessage to Signal can feel like a big leap, but honestly, it’s one of the best moves you can make if you value privacy and secure communication. I've been a Signal user for years now, and while the transition wasn’t perfect out of the gate, I’ve picked up some useful tips to make the switch smooth and painless. If you’re ready to take control of your messages and leave iMessage behind, this guide will walk you through everything step-by-step.

Why Consider Moving from iMessage to Signal?

First off, a bit of context. iMessage is deeply integrated into iPhones and Macs, which makes it super convenient. But Signal offers end-to-end encryption that’s open source and widely trusted by privacy advocates. Plus, Signal works cross-platform — so if you ever swap your iPhone for Android, your chats come with you seamlessly.

Here’s why I recommend Signal:

Step-by-Step: How to Migrate from iMessage to Signal

Now, onto the practical stuff. Just installing Signal isn’t enough; you need to make sure your contacts can reach you there, and that your old iMessages don’t cause confusion. Here’s how I did it:

  1. Install Signal on your iPhone

    Go to the App Store, download Signal, and follow the prompts to register your phone number.

  2. Tell your contacts you’re switching

    This sounds basic, but a quick heads-up message to your important contacts works wonders. Signal also shows you which contacts are already on the app, so you can start conversations there immediately.

  3. Deactivate iMessage for your number

    This is a crucial step that many people miss. If you don’t turn off iMessage, your friends’ iPhones will keep trying to send you messages as iMessages — which you won’t see if you’re on Signal only.

    To do this:

    1. Open Settings on your iPhone.
    2. Go to Messages.
    3. Toggle off iMessage.

    If you no longer have your iPhone, Apple has a dedicated tool to deregister your phone number from iMessage at selfsolve.apple.com.

  4. Turn off SMS forwarding on your Mac and iPad

    Otherwise, messages might still try to route through Apple’s servers and cause confusion.

    Go to Settings > Messages > Text Message Forwarding and make sure your devices are unchecked.

  5. Start new conversations in Signal

    Open Signal, and invite your contacts who aren’t on it yet. The app makes this easy by suggesting contacts.

  6. Back up your Signal data

    Signal does not sync your chat history via the cloud for privacy reasons, so if you switch devices, you’ll need to manually transfer data or start fresh. On iPhone, the app uses encrypted local backups — just go to Settings > Chats > Chat Backups to enable and create a backup.

Tips & Tricks I Learned the Hard Way

Switching messaging apps isn’t always smooth sailing, so here are some practical tips I wish I’d known up front.

1. Deactivating iMessage early avoids lost texts

I ignored turning off iMessage for a week, and some friends were saying my replies were delayed or not showing up. Once you turn iMessage off, ask a friend to send you a test SMS and a test Signal message to make sure everything is routing correctly.

2. Use Signal’s “Note to Self” for reminders

Signal has a neat "Note to Self" chat which is perfect for quick reminders, links, or anything you want to keep handy across devices. It’s like your own private notepad inside the app.

3. Beware of contact syncing quirks

Signal uses your phone contacts, but sometimes it takes a while to update new Signal users. I found that closing and reopening the app or refreshing the contacts list helps if a friend’s Signal status doesn’t appear immediately.

4. Group chats require re-creating

Unfortunately, there’s no way to transfer iMessage group chats to Signal. You’ll want to manually create new groups on Signal and invite the same people. Pro tip: Copy the group name and description from iMessage to keep things clear.

5. Customize notifications to avoid confusion

Signal lets you customize notification sounds and vibrations per contact or group. I changed my Signal tone to something noticeably different from iMessage to immediately know which app I’m getting messages on.
