How virtual numbers helped me build an international real estate service
Hi! My name is Zlatoslava Koval, and I’m a real estate agent and relocation specialist in Manchester.
My clients are people relocating to the UK from Ukraine, Europe and the US: IT specialists, students, and families looking for “move-in ready” housing even before they land.
The problems before HotTelecom
Before I started using virtual numbers, communication was quite chaotic:
Ukrainian clients preferred Telegram and Viber but couldn’t call a UK number cheaply.


Some inquiries came from Spain and Poland – people didn’t fully trust a “foreign” country code.

For every platform (WhatsApp, listings, websites) I had to use different SIM cards and physical phones.

I often work from my laptop in cafés or coworking spaces, and managing several phones at once was simply not realistic.
It became clear that I needed a single communication system that would allow me to:
have local numbers from different countries;

receive calls and messages in one interface;

quickly connect new numbers for specific projects or campaigns.

That’s when I discovered HotTelecom.

Why I chose HotTelecom
I tested several providers, but HotTelecom turned out to be the most convenient for my real estate workflows.
Key advantages:
Numbers from multiple countries – Ukraine, Poland, Germany, Spain, the US, the UK. Clients see a familiar country code and feel more confident.

Flexible call forwarding – I receive calls from any number on a single phone or app, no matter where I physically am.


Messenger support – I use some numbers specifically for WhatsApp and other channels, which is crucial for quick first contact.

Simple dashboard – I can manage all telephony myself, without a technical team.

How I integrated HotTelecom into my work
Starting with one core direction
First I connected a UK and a Ukrainian number.
The UK number – for local listings and property portals.
The Ukrainian number – for social media campaigns and relocation consultations.

Adding European numbers
As more clients from the EU appeared, I added Polish and German numbers.
In listings, people see a familiar country code, while all calls still arrive in one interface on my side.

Using virtual numbers in the sales funnel

one number for first contact (ads / listing platforms);

one number for VIP clients and corporate customers;

a dedicated WhatsApp number where I send video tours of apartments and contracts.


Analytics and control
I can see which country and which number each inquiry comes from, and separately track the performance of campaigns in Ukraine, Poland or Germany.

What this gave my business
More trust from clients
When someone in Kyiv sees a Ukrainian number, or a client in Warsaw sees a Polish one, the trust barrier drops. They feel they’re talking to someone “on their side”.


Less cost and chaos
I got rid of multiple SIM cards and extra phones. Everything runs over the internet – I only need a smartphone and a laptop.

The freedom to work from anywhere
I can travel to London for a few days or visit Ukraine – clients still call the same familiar numbers and always reach me.

Easier scaling
If tomorrow I want to launch a separate line for clients from France or Italy, I just buy a new virtual number in my account – no paperwork, no hassle.

Tips for fellow real estate professionals
Use local numbers
For buyers and renters, it’s important to feel that you genuinely work with their local market.

Separate numbers by purpose
One for ads, one for VIP clients, one for messengers. This makes analytics and workload control much easier.


Plan integration with your CRM or tracking from day one
Even a simple Google Sheet with leads plus a note about which number they used already gives you clarity on what works best.

Don’t be afraid of VoIP solutions
For a real estate agent, it’s not “complex tech” – it’s a tool that helps you look professional and stay reachable for clients 24/7 (within a healthy schedule).
