If you've ever grabbed your second phone only to realize your WhatsApp messages were stuck on the first, you're not alone. This is a daily hiccup for people who rely on multiple devices, especially those who balance personal and work phones.
WhatsApp rolled out a solution not too long ago: Companion Mode. With it, one account can now run on two phones—no browser workarounds, no sketchy third-party apps. If switching between devices is part of your routine, this update removes a pain point you didn’t know could be fixed.
This guide breaks down what the feature does and walks you through how to use WhatsApp on two phones.
What is WhatsApp Companion Mode?
Launched in April 2023, Companion Mode lets you add up to four other phones to your existing WhatsApp account. Once linked, these devices all receive messages and calls—regardless of whether your main phone is connected to the internet.
If you've ever wondered how to link WhatsApp to another phone, this feature makes the process simple and secure. Before this, WhatsApp’s multi-device setup was limited to web and desktop. Now, with phones included, it’s easier to stay connected across different devices, whether you’re on iOS or Android.
Each phone you connect works on its own, and your conversations stay encrypted from end to end, just like always.
What makes Companion Mode so useful?
Having WhatsApp on more than one phone changes how you communicate when you're moving between devices. Learning how to use WhatsApp on two phones with the same number can simplify daily workflows. It’s not just about convenience—it’s about removing roadblocks.
Here’s what people tend to appreciate most:
- No juggling: Open your chats on whichever phone is closest.
- Stay connected: Messages don’t stop flowing even if your primary phone dies.
- Less disruption: You can pause one device, pick up another, and carry on without resyncing.
- Better coverage: Teams using a shared WhatsApp line can now spread the load.
For folks who work on the go or split time between phones, it simplifies the entire experience.
Privacy and security
Even with multiple phones connected, WhatsApp doesn’t compromise privacy. Every message remains locked behind end-to-end encryption, and each device sets up its own secure connection.
So while the feature adds flexibility, it doesn’t compromise on what’s protected.
How to use WhatsApp on two phones with the same number
With Companion Mode, linking another phone to your existing WhatsApp account is surprisingly straightforward. You won’t need your SIM card in both phones, and there’s no complicated syncing involved.
While some users search for how to use WhatsApp on two phones without QR code, the current method still requires a quick scan during setup—but after that, both phones function independently.
Once the phones are linked, everything—your messages, media, calls—gets mirrored. Both phones stay in sync, and you can send or receive chats from either one at any time.
This is especially handy for people who switch between a personal and work phone, travel often, or just like having a backup device for communication.
Using WhatsApp on a linked Android Companion phone
If your second phone is an Android, linking it takes just a couple of minutes. Once you’ve set it up, the app works just like it does on your main device.
Here’s how to get it running:
- Open the Google Play Store on your Android phone.
- Search for "WhatsApp Messenger" and install the app.
- Launch it, and instead of entering your phone number, tap on "Link to existing account."
- On your main phone, open WhatsApp, go to Settings > Linked Devices > Link a Device, and scan the QR code.
Don’t skip these settings:
- Head to your phone’s app settings and make sure WhatsApp notifications are enabled.
- Disable battery optimization for WhatsApp so messages arrive without delay.
- If prompted, allow the app access to media and files.
Some features won’t carry over to your second device. You won’t be able to share your live location, update your status, or manage broadcast lists from the companion phone. For everything else, though, it’s business as usual.
Using WhatsApp on a linked iPhone Companion phone
The iPhone version works similarly to Android, though you’ll need to tweak a few settings to keep things running smoothly.
Here’s what you need to do:
- Open the App Store on the second iPhone and install WhatsApp.
- Launch the app and tap “Link to existing account.”
- On your main phone, head to Settings > Linked Devices > Link a Device and scan the QR code that appears.
Adjust a few settings:
- Go to Settings > Notifications > WhatsApp and allow all notification types—banners, alerts, sounds, and badges.
- Enable Background App Refresh so the app stays updated even when you’re not using it.
- Keep in mind, your linked iPhone won’t back up chat history unless you switch it to your primary device.
You’ll notice the same limits as Android here. Live location, broadcast tools, and some account settings remain locked on the companion phone.
How to set up WhatsApp on two phones (step by step)
Companion Mode works the same way on Android and iPhone, though the screens look a little different. If you’ve been wondering how to use WhatsApp on two mobiles, here’s a simple walk-through for both platforms to help you link your second phone without any guesswork.
For Android
Step 1: Install WhatsApp on your second Android phone from the Google Play Store.
Step 2: Open the app and tap the three-dot menu in the top-right corner.
Step 3: Choose “Link to existing account.”
Step 4: Open WhatsApp on your main phone and go to Settings > Linked Devices > Link a Device.
Step 5: Use your fingerprint, PIN, or face unlock to verify it’s you.
Step 6: Scan the QR code on the new phone using your primary device.
Step 7: Let it sync—this usually takes a few seconds.
Step 8: Once synced, the second device will show your latest chats and messages. From there, you can jump in and start replying right away.
For iOS
Step 1: Open the App Store on your secondary iPhone and install WhatsApp.
Step 2: Launch the app and tap “Link to existing account.”
Step 3: On your primary phone, go to Settings > Linked Devices > Link a Device.
Step 4: Authenticate with your Face ID, Touch ID, or passcode.
Step 5: Point your main phone at the QR code on the iPhone screen.
Step 6: Wait for everything to sync—this only takes a moment.
And just like that, your chats will be available on both devices.
Limitations of using WhatsApp on two phones
As helpful as Companion Mode is, it does come with a few boundaries. Knowing what you can and can’t do will save you some surprises down the road.
- You can link four extra devices, in addition to your main one.
- If your primary phone is inactive for 14 days, all linked devices will be logged out.
- Only recent messages get synced when linking a new device. Older messages don’t carry over.
- Some features are unavailable on linked phones, such as sharing your live location, updating your status, or managing broadcast lists.
- Each device has its own notification settings, so you’ll need to turn them on manually.
- Chat backups happen only on the primary device. The others don’t upload to iCloud or Google Drive.
