* GBWhatsApp and similar modifications violate the rules WhatsApp and may lead to account blocking. Use at your own risk.

⚠️ Attention: If your Samsung was released before 2020 or runs on Android 9 and below, the function Dual Messenger may be missing. In this case, consider alternative methods (sections 3–5).

2. Method 1: Official Dual Messenger (the most secure)

Function Dual Messenger from Samsung allows you to create a full copy of the application with separate data storage, notifications and settings. This method does not require root access, does not violate policy WhatsApp and is supported by most flagship and mid-budget models.

Step-by-step guide:

  1. Open Settings → Additional features → Dual Messenger.
  2. In the list of applications, find WhatsApp and activate the switch next to it.
  3. Click Install —the system will create a copy of the application with an icon in the form of two orange bubbles.
  4. Run WhatsApp (2) and register a new account, indicating the number of the second SIM card.

Features of the method:

  • 🔔 Notifications: Each account can be assigned a unique sound and vibration in Notification settings.
  • 📁 Data storage: Files (photos, videos) of the second account are saved in the folder /DualMessenger/WhatsApp/.

⚠️ Attention: On some models Samsung (for example, Galaxy S21 FE) after updating to One UI 6.0 function Dual Messenger may temporarily disappear from the menu. In this case, restart the device or check for software updates.

3. Method 2: WhatsApp Business as a second account

The official application WhatsApp Business is intended for entrepreneurs, but nothing prevents you from using it as a second personal account. This method is suitable for all models Samsung, including those without Dual Messenger.

Advantages of the method:

  • 🔒 Security: Official solution from Meta, without the risk of blocking.
  • 📊 Additional functions: Autoresponder, tags for chats, product catalog (you don’t have to use it).
  • 🔄 Synchronization: Works with the same contact database as a regular one WhatsApp.

How to install:

  1. Download WhatsApp Business from Google Play.
  2. When you first start, select Use another number and specify the second phone number.
  3. Confirm registration via SMS or call.
  4. In the application settings (⋮ → Settings → Company profile), you can disable all business functions, leaving only the messenger.

An important nuance: WhatsApp Business and regular WhatsApp may conflict when working simultaneously if they have common contacts. To avoid duplicate notifications:

  1. Open Settings → Applications → WhatsApp Business → Notifications.
  2. Disable notifications for groups that are already in your main account.
💡

If you use WhatsApp Business only as a second personal account, in the company profile settings, specify fictitious data (for example, “Private messages” in the “Business name” field). This does not violate the rules of the service, but eliminates unnecessary business functions.

4. Method 3: Parallel Space or Island (for models without Dual Messenger)

If your Samsung does not support Dual Messengerand WhatsApp Business is not suitable, you can use third-party cloning applications such as Parallel Space or Island. These tools create an isolated "sandbox" in which a copy runs WhatsApp with separate data.

Comparison of popular solutions:

App Free root access Whatsapp support Risks
Parallel Space ✅ Yes (with advertising) ❌ No ✅ Stable ⚠️ Possible lags
Island ❌ No ($5.99) ✅ Requires root ✅ Stable ⚠️ Complex setup
2Accounts ✅ Yes ❌ No ✅ Works ⚠️ Advertising in notifications

Instructions for Parallel Space:

  1. Install Parallel Space from Google Play.
  2. Launch the application and add WhatsApp to the list of cloned ones.
  3. Click on the icon WhatsApp in Parallel Space and register a new one account.
  4. In settings Parallel Space (⋮ → Settings → Notifications) enable the option Show notifications.
⚠️ Attention: Applications like Parallel Space may conflict with One UI on new models Samsung (for example, Galaxy S24). If after cloning WhatsApp it constantly crashes, try disabling battery optimization for Parallel Space in the device settings.
What to do if Parallel Space does not see the SIM card?

If, when registering the second WhatsApp in Parallel Space the SIM card is not detected, follow these steps:

1. Go to Settings → Connections → Mobile networks and make sure that the second SIM is active.

2. In settings Parallel Space enable the option Access to contacts and SMS.

3. Reboot the device and try registration again.

If the problem persists, try using Island (requires root access) or WhatsApp Business (section 3).

5. Method 4: Modified versions of WhatsApp (GBWhatsApp, FMWhatsApp)

Modified versions WhatsApp (for example, GBWhatsApp or FMWhatsApp) allow you to use two accounts on one device without cloning. These applications offer additional functions (hiding online status, customizing the interface), but have a serious drawback: they violate terms of use WhatsApp and can lead to permanent account blocking.

How to install GBWhatsApp:

  1. Download the APK file from the official website GBWhatsApp (do not use third-party sources!).
  2. Before installation, allow installation from unknown sources in Settings → Security.
  3. Install APK and register a second account with a different number.
  4. In the settings GBWhatsApp (⋮ → GB Settings → Dual App) activate the option Use Dual WhatsApp.

Risks of using modified versions:

  • 🚫 Account ban: WhatsApp actively blocks users of unofficial clients. The probability of a ban is up to 30% within a year.
  • 🔒 Data leak: Modified versions can collect your correspondence (there is no independent audit of the code).
  • 🔄 Unstable work: Frequent synchronization errors, especially after updates Android.
⚠️ Attention: If your main account WhatsApp is tied to important data (work, business), do not use modified versions. The risk of losing access to chats and contacts is too high. For personal use, consider the official alternatives (sections 2–3).
