How to Use WhatsApp Without a SIM: Guide to Alternative Methods

Autore: Francesco Zinghinì | Data: 2 Gennaio 2026

WhatsApp has become an indispensable communication tool for billions of people around the world. Its ease of use and wide range of features make it the preferred choice for messaging, calling, and file sharing. Traditionally, activating and using WhatsApp is tied to a phone number associated with a physical SIM card. However, there are several situations where you might want or need to use WhatsApp without a SIM inserted in your main device, or even without owning a dedicated one for the account. Whether it’s for privacy reasons, to use a Wi-Fi-only tablet, to manage a business account, or simply to explore the possibilities, this comprehensive guide will show you how to do it.

Have you ever wondered if it is possible to unlink your WhatsApp account from the traditional SIM card? The answer is yes, and in this article, we will explore in detail the most effective and secure methods to achieve this goal. We will analyze options that leverage landline numbers, virtual numbers, and even the ingenious use of a second phone as a bridge. We will understand the pros and cons of each solution, providing you with all the necessary information to choose the one best suited to your needs. Get ready to discover a new way of understanding your WhatsApp experience, more flexible and adaptable to your specific requirements.

Why Use WhatsApp Without a Dedicated SIM?

Before diving into the technical solutions, it is useful to understand the reasons that might drive a user to seek alternatives to the standard use of WhatsApp tied to a SIM.

  • Privacy: Using a number not directly linked to your main identity can offer an additional layer of anonymity.
  • Secondary Devices: Many people own tablets or old smartphones connected only via Wi-Fi. Enabling WhatsApp on these devices without a SIM opens up new usage possibilities.
  • Multiple Accounts: For those who need to separate personal and work communications, or manage multiple businesses, having a WhatsApp account not tied to the main SIM can be a practical solution.
  • Avoid Roaming Costs: When traveling abroad, using WhatsApp via Wi-Fi with a virtual or landline number can help avoid expensive data roaming charges tied to your home country’s SIM.
  • Testing and Development: Developers or testers might need to activate multiple instances of WhatsApp for verification purposes without having to use as many physical SIM cards.
  • Temporary Number: For short-term interactions (e.g., occasional online sales) where you do not wish to share your main number.

Understanding these motivations helps us better evaluate the utility of the methods we are about to describe.

Method 1: Use an Existing Landline Number

Perhaps the simplest and most direct method, if you already own a landline, is to use it to activate WhatsApp. WhatsApp requires a phone number capable of receiving calls or SMS for verification. Although landlines traditionally do not receive SMS, the phone call verification option makes this method viable.

Requirements:

  • An active landline phone number.
  • The landline phone handset nearby to receive the verification call.
  • A smartphone or tablet on which to install WhatsApp.

Step-by-Step Procedure:

  1. Install WhatsApp: Download and install the latest version of WhatsApp from the Play Store (Android) or App Store (iOS) on the device you intend to use.
  2. Start the Registration Process: Open WhatsApp and accept the terms and conditions. When asked to enter the phone number:
    • Select the correct international country code for your country (e.g., +1 for the US, +39 for Italy).
    • Enter your full landline number, including the area code.
  3. Wait for SMS Verification (which will fail): WhatsApp will initially attempt to send a verification SMS. Since you are using a landline, this attempt will most likely fail. Don’t worry, this is normal.
  4. Choose the “Call Me” Option: After a few minutes (usually 1 to 5 minutes), the option to receive the verification code via call will become available. Select “Call Me”.
  5. Receive the Verification Call: Your landline will ring. Answer the call: an automated voice will tell you the 6-digit verification code. Write this code down carefully.
  6. Enter the Verification Code: Go back to the WhatsApp app on your smartphone/tablet and enter the 6-digit code you just received.
  7. Complete Setup: If the code is correct, WhatsApp will be activated. You can then proceed with setting up your profile (name, photo, etc.).

Pros:

  • Reliability: Uses a number you own, which is stable and secure.
  • No Extra Cost: If you already have a landline, there are no additional costs to obtain the number.
  • Simple: The procedure is relatively easy to follow.

Cons:

  • Access to Landline: Requires physical access to the landline phone for the initial verification call.
  • Not Portable (the number): The landline number is tied to a location.
  • Possible Issues with WhatsApp Business: Some advanced features of WhatsApp Business might have limitations or require additional verification with landline numbers.

This method is ideal for those who want a stable WhatsApp account on a secondary device connected to home or office Wi-Fi, where the landline is easily accessible.

Method 2: Buy a Virtual Phone Number (VoIP)

Virtual phone numbers, often based on VoIP (Voice over Internet Protocol) technology, represent a flexible and increasingly popular solution. These numbers are not tied to a physical SIM or a traditional phone line but work via the internet. Many providers offer virtual numbers capable of receiving SMS and/or calls, making them perfect for WhatsApp verification.

How Virtual Numbers Work:
A virtual number is a real phone number, but managed entirely online. When someone calls or sends an SMS to this number, the communication is routed via the internet to the app or web interface of the VoIP service provider.

Popular Virtual Number Providers:
There are numerous services offering virtual numbers. Some of the most well-known include:

  • Skype Number
  • Google Voice (limited geographic availability)
  • TextNow
  • Numero eSIM (some providers offer virtual numbers in addition to eSIM plans)
  • Specific VoIP services offering DID (Direct Inward Dialing) numbers.

Choosing the Right Provider:

  • Ability to Receive SMS/Calls: Ensure the chosen service allows SMS reception or, alternatively, calls for WhatsApp verification. Not all virtual numbers have SMS functionality enabled.
  • Cost: Prices vary. Some offer free numbers with limited features (often ad-supported), while others require a monthly or annual subscription.
  • Service Reliability: Look for reviews and assess the provider’s reputation to avoid unreliable services that could cause the loss of the number (and thus the WhatsApp account).
  • Country of the Number: Choose a number from the country you prefer. For WhatsApp, it usually doesn’t matter, but it might affect your contacts’ perception.

General Procedure for Activating WhatsApp with a Virtual Number:

  1. Get a Virtual Number: Register with a provider of your choice and purchase or activate a virtual number that can receive SMS or calls.
  2. Install WhatsApp: On the desired device (smartphone, tablet).
  3. Start Registration on WhatsApp: Open WhatsApp.
  4. Enter the Virtual Number: When prompted, enter the virtual number you obtained, complete with the international country code.
  5. Receive the Verification Code:
    • Via SMS: If your virtual number supports SMS reception, you should receive the code directly in your VoIP provider’s app or web interface.
    • Via Call: If SMS reception is unavailable or fails, wait for the “Call Me” option. The call will be routed to your VoIP service.
  6. Enter the Code: Input the 6-digit code into WhatsApp.
  7. Complete Setup: Configure your WhatsApp profile.

Pros:

  • Flexibility: Accessible from any device with an internet connection.
  • Privacy: Can offer a higher degree of separation from your personal identity.
  • Ideal for Multiple Accounts: Easy to obtain multiple virtual numbers for different accounts.
  • Portability: Not tied to a physical SIM or a location.

Cons:

  • Recurring Costs: Many reliable virtual number services require a subscription.
  • Provider Reliability: The stability of your WhatsApp account depends on the continuity of the VoIP provider’s service. If you lose access to the virtual number, you could lose access to WhatsApp.
  • Possible Blocking by WhatsApp: Although rare with serious providers, WhatsApp occasionally blocks ranges of numbers known to be used for spam or abuse, which could include some low-quality virtual numbers.
  • Initial Complexity: Choosing and configuring the VoIP provider may require a bit more research.

Virtual numbers are a powerful solution, especially for those seeking flexibility and management of multiple accounts. It is crucial to choose a reliable provider to ensure the longevity of your WhatsApp account.

Method 3: Use WhatsApp Web/Desktop with a “Bridge” Phone (No SIM in Main Device)

This method does not allow you to activate WhatsApp without a SIM or number, but it allows you to use WhatsApp on a device (like a PC or tablet) without that device having a SIM, provided you already have an active WhatsApp account on a smartphone (which we will call the “bridge phone”). The bridge phone needs the SIM (or one of the alternative methods described above) only for the initial setup and periodic reconnections, but not necessarily all the time.

How WhatsApp Web/Desktop Works:
WhatsApp Web and WhatsApp Desktop are extensions of your main WhatsApp account on your phone. They sync messages between your phone and your computer/tablet, allowing you to send and receive messages conveniently from a device with a larger screen and physical keyboard.

New Multi-Device Mode:
Recently, WhatsApp introduced an improved multi-device feature. Once companion devices (like PCs or tablets) are linked, they can send and receive messages regardless of whether the main phone is connected to the Internet, for a certain period of time (up to 14 days if the main phone stays offline). This is a big step forward compared to the past, where the main phone had to be constantly online.

Procedure:

  1. Active WhatsApp Account: Ensure you have an active and working WhatsApp account on a smartphone (the “bridge phone”). This account must have been verified via SIM or one of the alternative methods (landline, virtual number).
  2. Install/Open WhatsApp on Secondary Device:
    • For PC (Windows/Mac): Download and install WhatsApp Desktop from the official WhatsApp website or the Microsoft Store/Mac App Store.
    • For Tablet or Other PC (via Browser): Open a web browser (Chrome, Firefox, Edge, Safari) and go to web.whatsapp.com.
  3. Link the Device:
    • Open WhatsApp on your bridge phone.
    • Go to Menu (the three vertical dots on Android) or Settings (on iOS).
    • Select “Linked devices”.
    • Tap “Link a device”.
    • Use your bridge phone’s camera to scan the QR code shown on WhatsApp Desktop or WhatsApp Web on your secondary device.
  4. Use WhatsApp on Secondary Device: Once linked, you can use WhatsApp on your PC or tablet. Thanks to the new multi-device mode, your bridge phone does not need to remain constantly connected to the Internet, although it is advisable for it to connect periodically to keep synchronization active and avoid automatic disconnection after a long period of inactivity (over 14 days).

What “Without SIM in Main Device” Means in This Context:
If your bridge phone has activated WhatsApp using, for example, a virtual number (Method 2) or a landline (Method 1), then even that bridge phone does not need a physical SIM inserted to keep WhatsApp active, as long as it has a Wi-Fi connection for communication. Consequently, the entire system (bridge phone + secondary device with WhatsApp Web/Desktop) can function without any SIM being actively in use at that specific moment, provided the WhatsApp account was initially validated.

Pros:

  • Convenience: Great for using WhatsApp on a PC or tablet.
  • Synchronization: Messages are synced across all linked devices.
  • (Limited) Independence of Main Phone: With the new multi-device mode, the main phone doesn’t always have to be online.
  • No Extra Cost (if you already have WhatsApp): Leverages your existing account.

Cons:

  • Requires an Existing Account: It is not a method to create a WhatsApp account without a number, but to extend its use.
  • Not for All Mobile Devices: WhatsApp Web is primarily designed for desktops and browsers, while the dedicated WhatsApp app for tablets might have specific requirements.
  • Feature Limitations: Some features might be limited on WhatsApp Web/Desktop compared to the main mobile app (although feature parity is improving).
  • Periodic Disconnection: If the main phone stays offline for more than 14 days, linked devices will be disconnected.

This method is excellent for those who want the convenience of WhatsApp on multiple screens, and the new multi-device mode makes it even more practical by reducing dependence on the main phone’s constant connection.

Method 4: Free “Texting” Apps (With Caution)

Some apps offer free phone numbers, often US or Canadian, that can be used to send and receive SMS and sometimes calls. TextNow is an often-cited example. These services can, in theory, be used to verify WhatsApp.

How They Work:
These apps provide you with a real phone number that works over Wi-Fi or mobile data. They are often ad-supported or offer premium paid features.

Procedure (General):

  1. Download and Install the Texting App: Find a reliable app (read reviews!) and install it.
  2. Get a Free Number: Complete registration and obtain your free number.
  3. Install WhatsApp.
  4. Verify WhatsApp: Enter the number obtained from the texting app into WhatsApp and wait for the verification SMS (which should arrive in the texting app) or use the “Call Me” option.

Risks and Considerations:

  • Reliability and Number Lifespan: Free numbers can be recycled or deactivated without notice, especially if not used frequently. If you lose the number, you lose access to WhatsApp, and it might be difficult to recover the account.
  • Privacy: Free services might not offer the best privacy guarantees. Read their terms of service carefully.
  • Blocking by WhatsApp: WhatsApp is aware of these services and might actively block numbers coming from providers known for abuse or mass account creation. This is the biggest risk.
  • Service Quality: SMS or call reception might be unreliable.
  • Ads: Free apps are often full of advertisements.

When It Might Make Sense (With Reservation):
This method could be considered for very temporary uses or for testing, where losing the WhatsApp account would not be a serious issue. It is not recommended for main or long-term WhatsApp accounts.

Pros:

  • Potentially Free: The main (and often only) advantage.

Cons:

  • Very High Risk of Losing Account: Very likely.
  • Unreliability: Both of the number and code reception.
  • Privacy and Security Issues.
  • Geographic Limitations: Many of these apps mainly offer US/Canada numbers.

Given the high probability of issues, this method is generally discouraged for serious and continuous WhatsApp use.

Security and Precautions When Using WhatsApp Without a Traditional SIM

Regardless of the chosen method, there are some important security considerations:

  • Protect Your Alternative Number: Whether it’s a landline, virtual, or temporary number, this number is the key to your WhatsApp account. Ensure you maintain access to it. If you use a paid service, make sure the payment is up to date to avoid losing the number.
  • Enable Two-Step Verification on WhatsApp: This is a crucial security measure. It adds a six-digit PIN that will be requested periodically and when you register your number on WhatsApp again. This protects your account even if someone manages to intercept your SMS/call verification code.
    • To enable it: Open WhatsApp > Settings > Account > Two-step verification > Enable.
  • Chat Backups: Regularly back up your chats (to Google Drive for Android, iCloud for iOS). If you lose access to your account or device, you will be able to recover your conversations.
  • Beware of Phishing: Be cautious with messages or calls requesting personal information or codes, even if they seem to come from WhatsApp or your virtual number provider.
  • Choose Reliable Providers: Especially for virtual numbers, opt for well-known services with good reviews. Avoid solutions that are “too good to be true.” If you are interested in better understanding what an IP address is and why you should protect it, you might find useful insights for your general online security.

Carefully managing these aspects will help you keep your WhatsApp account secure and accessible.

Considerations for Using WhatsApp Business Without a SIM

WhatsApp Business is a version of the app designed for small and medium-sized businesses, with additional features like business profiles, quick replies, and product catalogs. WhatsApp Business can also be activated using the methods described above (landline or virtual number).

  • Landline and WhatsApp Business: Using the business landline number for WhatsApp Business is a very common and professional choice. It allows customers to contact the company via a number they already know.
  • Virtual Number and WhatsApp Business: A virtual number can be useful if you want a dedicated number for customer support via WhatsApp, separate from main phone lines, or if your business operates mainly online without a physical location with a landline.

Considerations regarding receiving the verification code (SMS or call) remain the same. Ensure the chosen number (landline or virtual) is presented professionally to your customers.

Maintenance of Your WhatsApp Account Activated Without a SIM

Once you have activated your WhatsApp account with an alternative method, here are some tips for its maintenance:

  • Keep the Alternative Number Active: If you use a paid virtual number, ensure the subscription is always active. If you use a landline, obviously, the line must remain operational.
  • Internet Connection: WhatsApp needs an internet connection (Wi-Fi or mobile data, if available on the device) to work. Ensure the device you use WhatsApp on has regular internet access.
  • App Updates: Keep the WhatsApp app updated to the latest version to benefit from new features and security patches.
  • Do Not Over-Share the Number (if used for privacy): If one of the goals was privacy, be selective about who you share this alternative WhatsApp number with.
  • Periodic Check of Bridge Phone (if using WhatsApp Web/Desktop): If you rely on Method 3, ensure your “bridge phone” (the one with the main WhatsApp account) connects to the internet occasionally to avoid disconnection of linked devices.

By following these simple guidelines, you can enjoy your WhatsApp account activated without a traditional SIM for a long time.

Conclusions

The need to use WhatsApp without a physical SIM card in the main device or even without a traditional mobile number is more common than one might think. Reasons range from seeking greater online privacy, to the practicality of using the app on secondary devices like Wi-Fi-only tablets, to the need to manage multiple accounts to separate personal from work communications. As we have seen, there are several viable strategies, each with its specificities, advantages, and potential drawbacks.

The method leveraging an existing landline phone number proves to be a solid solution with no additional costs for those who already have a landline, ideal for home or office use. Verification via voice call bypasses the inability to receive SMS on landlines, making this option simple and reliable.

Purchasing a virtual phone number (VoIP) offers remarkable flexibility. This solution is particularly suitable for those needing a dedicated number not tied to a physical SIM, easily manageable online and usable from any device with internet access. In this case, it is fundamental to rely on reputable and reliable VoIP service providers to ensure the stability of the number and, consequently, the associated WhatsApp account. Although it may entail a periodic cost, the benefits in terms of portability and separate account management can be significant. It might be useful to compare different options, much like doing an electricity and gas rate comparison to find the most convenient and suitable solution.

The WhatsApp Web/Desktop mode, enhanced by the recent multi-device feature, does not allow you to create an account from scratch without a number, but it extends the use of an existing account to PCs and tablets much more independently from the main phone than in the past. This is a huge advantage for productivity and convenience, allowing you to stay connected even if the main phone is not immediately available or connected, provided the account was initially validated.

Finally, free texting apps, while tempting due to the lack of costs, present significant risks in terms of number reliability, privacy, and potential blocking by WhatsApp. They are generally discouraged for continuous and reliable use.

Regardless of the choice, account security must remain a priority. Activating two-step verification is an essential step to add an extra layer of protection. Maintaining access to the number used for verification (whether landline or virtual) and understanding how tools like a VPN for online security work can contribute to a safer and more conscious digital experience.

Ultimately, using WhatsApp without a traditional SIM is absolutely feasible in 2025. By choosing the method most suited to your needs and taking the necessary precautions, you can enjoy greater flexibility and control over your messaging experience.

Frequently Asked Questions

Is it legal to use WhatsApp without a SIM?

Yes, it is perfectly legal. The methods described, such as using a landline or virtual number for verification, or using the “Linked Devices” feature, do not break any laws. The important thing is that the number used for initial registration is legitimately accessible by you.

Can I use the same WhatsApp account on two phones simultaneously with these methods?

Yes, by using the “Linked Devices” feature. After activating WhatsApp on your main phone (with a SIM or one of the methods described above if that is your “main” activation device), you can link up to four other devices, including other smartphones, which will be able to access the same WhatsApp account. However, it is not possible to activate the same number on two different primary WhatsApp installations.

What happens if I lose access to my landline or virtual number used for registration?

Losing access to the number used for registration can be a problem. If you need to re-verify your number (for example, by reinstalling WhatsApp or changing phones), you won’t be able to do so without accessing that number again to receive the code. For virtual numbers, consider paid services that guarantee more stable access. For landlines, make sure to keep it active. It is also advisable to enable two-step verification on WhatsApp with a PIN and a recovery email address for greater account security.

Is WhatsApp Web the same thing as using WhatsApp without a SIM?

Not exactly. WhatsApp Web and WhatsApp Desktop are clients that allow you to access your WhatsApp account from a computer. They work via the “Linked Devices” feature, so your WhatsApp account must already be active on a smartphone. If you have activated WhatsApp on a smartphone (even using a landline or virtual number, without a physical SIM inside it), then you can use WhatsApp Web/Desktop. The guide focuses on activating and using WhatsApp on mobile devices (smartphones/tablets) without a SIM being physically present in that device.

Do I need an Internet connection to use WhatsApp without a SIM?

Yes, absolutely. WhatsApp requires an Internet connection (Wi-Fi or mobile data, if the device supports them via another source) to send and receive messages, regardless of whether there is a SIM in the device or not. The SIM is mainly used for phone line identification and receiving the initial verification code.

What are the main risks of using free virtual numbers for WhatsApp?

The main risks include:
* Loss of number: Free numbers can be revoked by the provider without notice.
* Reliability: They might not always receive verification SMS or calls reliably.
* Security/Privacy: Some free services might not be very transparent about data handling.
* Blocking by WhatsApp: WhatsApp might identify and block numbers coming from services known for abuse or terms violations.
If you opt for a virtual number, paid ones are generally safer and more reliable.

Can I make WhatsApp calls and video calls using these methods?

Yes. Once WhatsApp is activated and working on your device (via landline, virtual number, or as a linked device), all standard WhatsApp features, including voice calls and video calls, will be available, provided you have a stable Internet connection.

Is the activation procedure with a landline or virtual number very different between Android and iPhone?

The basic procedure for activating WhatsApp is very similar on Android and iPhone. The steps to download the app, enter the number, and the verification code are the same. Differences might lie in the specific user interface of each operating system to reach certain settings or in the interface of third-party apps providing virtual numbers, but the WhatsApp activation flow remains consistent.
