How to Use a Virtual Number to Receive SMS
A virtual number lets you receive SMS without a physical SIM card—useful for travel, privacy, or business needs. But not all services accept them the same way.
What is a virtual number and how does it work?
A virtual number is a phone number not tied to a physical SIM card. Instead of receiving calls and SMS through a phone chip, they arrive in an app, web browser, or online dashboard.
Unlike regular numbers, a virtual number works anywhere with an internet connection. You could be in Tunisia, Israel, or New Zealand—if your virtual number is active, you'll receive SMS sent to that number.
ELK Connect offers virtual numbers in several countries, including Canada, the United States, the United Kingdom, Puerto Rico, Lithuania, Israel, the Philippines, Tunisia, and New Zealand. Each number is tied to a specific country, meaning it displays that country's local dialling code.
What are the real uses for a virtual number?
For travellers
When you travel abroad, you need to stay reachable without paying steep roaming charges. A virtual number lets you receive SMS from your home country, even when you're physically elsewhere. Your contacts see a local number from your country, not an international one.
It's especially useful if you're away for several months—you keep a stable digital anchor point.
To protect your personal number
You don't want to give your real number to every online service, signup form, or registration. A virtual number acts as a go-between. If that number gets spam or misused, your real number stays protected.
For businesses and distributed teams
A small business can use a virtual number as a single contact point for customers, no matter where its staff are located. Calls and SMS arrive on a shared dashboard, making communication easier to manage.
For mobile top-ups and financial services
Some mobile top-up or money transfer services send confirmation codes by SMS. A virtual number can receive these codes, letting you manage top-ups from anywhere.
Where a virtual number works and where it hits limits
Services that accept virtual numbers
- Social media platforms (Facebook, Twitter, Instagram)
- Messaging services (WhatsApp, Telegram)
- Travel apps (Uber, Airbnb)
- Streaming services (Netflix, Spotify)
- Newsletter or forum signups
- OTP (One-Time Password) codes for some online services
Services that often reject virtual numbers
Banks and financial institutions are the most restrictive. Many refuse to send verification SMS to a virtual number. Depending on your bank and country, the system may detect that the number isn't linked to a physical SIM card and block verification.
Some government services, gambling operators, and strong authentication platforms also apply restrictions. Before relying on a virtual number for a critical service, check your institution's terms.
Never share an OTP or verification code received by SMS with anyone else. If someone asks for your SMS code, it's an attempt to fraudulently access your account.
How to receive SMS on a virtual number
Basic steps
- Choose a country for your virtual number (based on your need and use case)
- Activate the number on the ELK Connect platform
- Share this number with the service that needs to send you an SMS
- Log into your ELK Connect account to view received SMS
- Read the message and use the code or information it contains
Key points to remember
- You need an internet connection to check your SMS
- SMS usually arrives within seconds, but may take a few minutes depending on the network
- Each virtual number receives SMS sent to that specific number only
- You can manage multiple virtual numbers at once if needed
If you travel regularly to multiple countries, you can activate virtual numbers in each one. This lets your local contacts reach you without international calling charges.
Differences between a virtual number and an eSIM
| Aspect | Virtual number | eSIM |
|---|---|---|
| Requires a SIM chip | No | Yes (digital) |
| Receives calls | Depending on service | Yes, like a regular SIM |
| Receives SMS | Yes | Yes |
| Works offline | No | No |
| Cost | Generally cheaper | More expensive |
| Best for | Privacy protection, verification | Regular calls and SMS while travelling |
An eSIM is more complete—it works like a regular SIM card, but in digital form. A virtual number is lighter and easier to manage, but limited to receiving SMS and calls over the internet.
Pitfalls to avoid
Assuming all services accept virtual numbers
They don't. Before relying on a virtual number for something important (banking, government, identity), test it first or ask the service if it accepts numbers not linked to a physical SIM.
Sharing your virtual number too widely
While a virtual number offers some protection, sharing it with too many services reduces that benefit. Use it strategically.
Forgetting you need internet
A virtual number only works if you're connected to the internet. When travelling, make sure you have reliable access before counting on this number for urgent verification codes.
When to use ELK Connect for a virtual number
ELK Connect is useful if you need a stable number in a specific country, travel frequently, or manage contacts across multiple countries. The platform offers a single rechargeable balance, which simplifies cost management.
If you need calls in addition to SMS, you can combine a virtual number with other ELK Connect services, such as pay-per-minute international calls or an eSIM for your phone.
Keep your ELK Connect account credentials secret. Anyone with access to your account can see SMS received on your virtual numbers and potentially access associated accounts.
Real-world examples
Case 1: A traveller in Asia
Marie is travelling in the Philippines for three months. She activates a Canadian virtual number through ELK Connect. Her friends and family call this number without international charges. She receives confirmation SMS from her travel apps (Airbnb, Uber) without activating an expensive eSIM.
Case 2: An entrepreneur with a distributed team
Ahmed runs a small business with clients in Tunisia, Israel, and the United Kingdom. He activates three virtual numbers, one in each country. A central dashboard shows him all incoming calls and SMS, regardless of where his staff are located.
Case 3: Privacy protection
Sophie signs up for multiple online services for a personal project. Instead of giving her real number, she uses a virtual number. If one of these services sells her data or suffers a breach, her real number stays protected.
Key takeaways:
1. A virtual number receives SMS without a physical SIM card, ideal for travel and privacy protection.
2. Banks and government services often reject virtual numbers—always check with your institution before relying on one.
3. You need internet to check your SMS, unlike a regular SIM card.
