Virtual phone numbers rely on an internet connection instead of traditional phone infrastructure. So you don’t need a SIM card (Subscriber Identity Module), a separate device, or be tied to a fixed location. There are many ways to get a virtual phone number, but the quickest and easiest way is to sign up through a service provider. Before we get started, let’s explore the important things you should know — how virtual phone numbers work, common scenarios where they can be used, and step-by-step instructions for setting them up. I’ll also suggest a reputable option that suits most needs today.

What is a virtual phone number?
A virtual phone number is a type of phone number that uses the internet to make and receive calls or messages, instead of relying on traditional telecommunications networks. This type of number is not tied to a SIM card, phone line, specific device, or a fixed geographic location.
How does a virtual phone number work
A virtual phone number works using VoIP (Voice over Internet Protocol) technology, which converts voice or text messages into digital data and transmits them over the internet. Cloud servers are responsible for routing the signal to the right device for you — be it a smartphone, tablet, or laptop.
Unlike traditional landline or mobile phone numbers that rely on physical infrastructure such as cables, cell towers, or switchboards, a virtual phone number is entirely online. This means you can use it anywhere with an internet connection and can even log in to the same number on multiple devices at the same time.
For example, you can have a virtual number with a New York area code, make a call from your laptop in London, reply to a text message on your tablet, and then continue the conversation on your phone while you’re on the go — all using the same unique number.
Comparing Virtual Phone Numbers and Traditional Phone Numbers
For the person receiving the call, the experience between a virtual number and a traditional number is almost indistinguishable. But for the user, the two options are distinctly different. Here’s a detailed comparison:
Criteria
Virtual Phone Number
Traditional Phone Number
Technology
Operates on a VoIP platform, transmitting data over the Internet.
Calls and messages are transmitted over a wired (landline) or mobile network.
Mobility
Not tied to a specific device, SIM, or location. Can be used from anywhere with Internet access.
Landlines are tied to location and device. Mobiles are tied to SIM, carrier, and country.
Flexibility
Can be used on multiple devices at the same time, can be shared with multiple users.
Mainly tied to one person – one device. Landline phones are less flexible.
Cost
Cheaper, no hardware required. Flexible service packages, paid monthly or on demand.
Often more expensive, especially for landlines (installation, equipment, fees). Mobile with contract.
Setup
Quick and easy: choose a number, activate and use immediately on a device with Internet.
Landline requires installation. Mobile requires SIM/eSIM, network registration.
Scalability
Easy to expand: adding numbers, users or locations takes just minutes, no new equipment required.
Difficult to expand, need additional SIM, phone and hardware for each new user.
International capability
Can choose numbers in many area codes, even from other countries.
Restricted by network operator. When going abroad, you often have to pay roaming fees or change to a local SIM.
Internet Dependent
Needs an Internet connection to work.
No Internet required. Landlines still work even during power outages (in some cases).

Thus, virtual phone numbers offer better flexibility, savings and scalability, while traditional numbers still have the advantage of stability and not being dependent on the Internet.

Why should you consider using a virtual phone number?
From protecting your privacy to increasing flexibility, there are many reasons to own a virtual phone number. Here are the most common benefits:
Keeping personal information safe
Personal phone numbers are often associated with sensitive data such as your name, address and email. When shared widely, you are more likely to become a victim of data leaks, being sold to third parties or being used in scams. Virtual phone numbers help you keep your main number private, minimizing risks while still ensuring convenient communication.
Reduce spam and harassing calls
Posting your real number online can quickly lead to a series of advertising messages, spam calls and scams. With a virtual number, you can use it exclusively for service registration, advertising or public transactions. If the number is harassed, you can simply change it without affecting the main number.
Safer online transactions
Communicating with strangers on e-marketplaces, dating apps or new platforms always has potential risks. Virtual phone numbers help you maintain contact without worrying about revealing real information. If you detect abnormalities, you can easily cancel or change the number with just a few steps.
Contact anytime, anywhere
Not limited by location or country, virtual phone numbers only need the Internet to work. Whether you are traveling, moving or changing devices, people can still contact you via the same number without incurring roaming charges.
Easy to switch devices
Virtual numbers are not tied to a SIM or a single phone. You can receive calls and messages on your phone, tablet or computer, which is convenient for those who travel a lot, work on multiple devices or constantly change devices.
Separate work and personal life
If you work multiple jobs or often have to answer after hours, the line between work and private life can easily blur. Using a virtual phone number allows you to set clear boundaries — one for work, one for family and friends — without the need for multiple phones or SIM cards.

Is it safe to use a virtual phone number?
In general, virtual phone numbers are perfectly safe if you choose a reputable provider. In fact, they can be more secure than your real number, keeping your identity private and reducing the risk of information being leaked. Quality services often use encryption to protect your calls and messages from being tracked.

However, as with any online service, the level of security depends a lot on where you sign up. Free services in particular have many potential risks:
Reused numbers: Someone else may have used the number before, and you could receive unrelated messages and calls.

Shared numbers: Some free services allow multiple users to share the same number, reducing privacy.

Ads and malware: free services often come with intrusive ads, pop-ups, or tracking software.

Collecting personal data: untrustworthy providers may sell your data to third parties.

Unreliable service: your number may suddenly stop working without warning.

Poor security: basic protections like encryption are sometimes omitted.

Also, no matter how good a service you choose, posting your number publicly on social media, forums, etc. can still expose you to spam or scams.

How to register a virtual phone number:
Owning a virtual number is quick — it only takes a few minutes. Basic steps:
Choose a reputable provider.

Choose the country and type of number you want.

Sign up for an account (usually requires an email, sometimes a secondary number or verification documents).

Choose the right plan (pay as you go, monthly, or annually).

Set up your number on your device via the app or dashboard.

Start calling and texting.
