Knowing how to install WhatsApp on 2 devices with the same number is useful if you want to use WhatsApp on both your phone and another device such as a second phone, tablet, or computer. WhatsApp officially allows one phone number to be linked to multiple devices using its Linked Devices feature, making it possible to chat without constantly switching phones.
This article explains how the feature works, how to set it up step by step, and important things to keep in mind.

How WhatsApp Linked Devices Works
WhatsApp now supports multi-device use.
Key points to know:
- One phone number can be linked to multiple devices
- The primary phone remains the main account
- Linked devices sync messages securely
- No SIM card is required on the second device
This feature is official, safe, and supported by WhatsApp.
-
Requirements Before You Begin
Ensure you meet the basic requirements.
You need:
- An active WhatsApp account on your main phone
- Internet connection on both devices
- Latest version of WhatsApp installed
- Access to your primary phone for verification
Both devices must be online during setup.
-
Install WhatsApp on the Primary Phone
Your main phone must already have WhatsApp set up.
Confirm the following:
- WhatsApp is installed and verified
- Your chats are working normally
- Your number is active
- You can access the WhatsApp settings menu
The primary phone controls all linked devices.
-
Install WhatsApp on the Second Device
WhatsApp must also be installed on the second device.
Steps include:
- Download WhatsApp from the official app store
- Open the app
- Do not enter a phone number
- Wait for the QR code screen to appear
The QR code is used to link devices.
-
Link the Second Device to the Main Phone
This is the most important step.
On the primary phone:
- Open WhatsApp
- Tap the three-dot menu or settings
- Select Linked Devices
- Tap Link a Device
- Authenticate using fingerprint, face, or PIN
- Scan the QR code shown on the second device
The devices will sync automatically.
-
Use WhatsApp Independently on Both Devices
Once linked, both devices can be used normally.
You can:
- Send and receive messages
- Make voice and video calls
- View chats and media
- Receive notifications
The second device does not need the SIM card.
-
Understand Limitations of Linked Devices
There are a few important limitations.
Keep in mind:
- The primary phone must connect to the internet periodically
- Logging out of the main phone logs out linked devices
- Some older devices may not support all features
- Backup settings are controlled from the main phone
Despite this, functionality is nearly the same.
-
Link More Than Two Devices If Needed
WhatsApp allows multiple linked devices.
You can:
- Link up to four additional devices
- Use phones, tablets, or computers
- Manage linked devices from settings
- Remove devices anytime
This is useful for work and personal use.
-
Avoid Unofficial or Risky Methods
Some online methods are unsafe.
Avoid:
- Modified WhatsApp apps
- Third-party cloning apps
- APK files from unknown sources
- Sharing verification codes
These methods risk account bans and data theft.
-
Troubleshoot Common Linking Problems
If linking fails, try these solutions:
- Update WhatsApp on both devices
- Ensure both devices have stable internet
- Restart both devices
- Log out and try again
- Clear app cache if necessary
Most issues are resolved easily.
