What Is a Virtual Phone Number

How It Works

A virtual phone number lets you make and receive calls or texts using the internet instead of a regular phone line. You can get a virtual number for WhatsApp from a provider, then use it to sign up for WhatsApp Business. Here’s how it usually works:

You pick a number from a provider, like Sobot or another service.
The provider gives you access to the number through an app or web dashboard.
When you set up WhatsApp Business, you enter this number.
WhatsApp sends a code to your virtual number. You get the code through the provider’s app or website.
Enter the code in WhatsApp, and you’re ready to go!

Virtual phone numbers use VoIP (Voice over Internet Protocol) technology. This means all your calls and messages travel over the internet. You don’t need a SIM card or a physical phone line. You can even use the same number on different devices.

Tip: Make sure you have a strong internet connection for the best experience with your WhatsApp virtual number.

Aspect	Evidence
Definition	Virtual phone numbers are integrated with VoIP systems allowing calls over the internet, providing cost savings, scalability, and flexibility.
Global Users	Over 3 billion VoIP users worldwide as of 2023, with businesses forming a significant portion.

Common Issues and Solutions

Verification Problems

You might run into trouble when trying to complete WhatsApp verification with a virtual or temporary phone number. Sometimes, WhatsApp does not send the code, or the code never arrives. This can happen if the number has been used too many times or if the provider blocks certain messages. You may also see issues if your internet connection is weak.

Here are some tips to help you pass WhatsApp verification:

Choose a provider that supports WhatsApp verification codes. Not all virtual numbers work.
If SMS does not work, try the voice call option for the code.
Make sure your temporary phone number is active and able to receive messages.
Double-check your internet connection before starting the process.

If you use a solution like Sobot, you get step-by-step help for WhatsApp verification, making setup much smoother.

Policy Compliance

Staying compliant with rules is a big deal for any business using WhatsApp Business. Many companies face challenges because WhatsApp does not have built-in tools for message archiving or audit logs. This makes it hard to follow laws like GDPR, which require you to store and manage customer conversations safely.

Some important facts to keep in mind:

WhatsApp has almost 3 billion users, making it a target for security threats.
Regulators have fined companies millions for not keeping proper records of WhatsApp chats.
End-to-end encryption means you cannot easily monitor or archive messages.
Financial firms must keep all business messages for at least seven years, but WhatsApp’s features can make this tough.

To stay safe:

Use approved communication channels and set clear company policies.
Choose platforms like Sobot that offer centralized management and help you meet compliance needs.

Security Tips

Protecting your WhatsApp Business number is key. Traditional phone numbers can be attacked with SIM swapping or phishing. Virtual numbers, especially those in the cloud, help break this attack chain. They are not tied to a physical SIM, so hackers have a harder time getting in.

Here are some ways to keep your account safe:

Use different numbers for different services to protect your privacy.
Rotate or change your virtual number if you suspect a breach.
Watch out for phishing links and never share your WhatsApp verification code.
Pick a provider with strong security features and support for two-factor authentication.

A recent case showed over 300,000 WhatsApp numbers exposed online, leading to risks like identity theft and fraud. Always stay alert and use trusted providers. Sobot’s WhatsApp Business API includes advanced security and privacy features, helping you keep your business safe and compliant.
