What is a virtual UK phone number?
A virtual UK number looks and works like any other British number. The difference is there's no landline or SIM behind it: calls arrive over the internet, and you answer them in an app, an IP phone, or forward them to whatever number you like, in any country.
For the person calling you, the process is the same as with a regular phone number. They dial a UK number, for example, a London 020 number, and pay their normal local rate, with no idea that you're located in another country.
Types of UK numbers you can get from overseas with Zadarma
Local (geographic) numbers
These are city-specific numbers with familiar area codes: 020 for London, 016 for Manchester, 012 for Birmingham, 0113 for Leeds, and many more. For companies focused on a particular city, a local number is the practical choice. Customers call local numbers far more often than international ones.
UK mobile numbers (07)
Virtual UK mobile numbers starting with 07 support both voice calls and 2-way SMS. You can receive calls anywhere in the world, while SMS lets you stay reachable by text and reach clients with reminders, updates, or other important information.
Keep in mind that a virtual UK mobile phone number works over the internet via an Android, iOS, Windows, macOS app, an IP phone, webphone or CRM, not through a physical SIM, so a stable internet connection is required.
Toll-free numbers (0800)
With a toll-free number, the call is free for the person calling, while the number owner covers the cost. These numbers are a classic choice for customer support lines and sales, because customers are more likely to call when it's free.
Important: Due to Ofcom, the UK telecom regulator, anti-fraud rules, calls to UK numbers cannot be made from outside the UK using your virtual UK number. If you are physically located abroad, outgoing calls to the UK will not connect.
How to get a UK number from abroad: a step-by-step guide
- Create a Zadarma account. Registration is free and takes a couple of minutes.
- Choose your number type and location. Top-up your account, then in the virtual numbers section, select the United Kingdom and pick the type you need — a geographic number for your chosen city, a mobile 07 number, or a toll-free 0800 number.
- Verify your details. Identity verification may be required before your number is activated. You can find the full list of available numbers and the activation requirements here.
- Connect your devices. Link the number to the free Zadarma app on iOS or Android, the desktop softphone, a browser-based webphone, or a hardware IP phone. You can find setup guides in the “Help - Programs for calls” section of your account.
- Set up call flow. Decide where your calls should go: straight to the app, to your existing mobile number in your current country, or through the free cloud PBX, with voicemail, greetings, and call distribution if you need them.

Who needs a UK number when overseas?
- Expats and long-term travellers. Banks, the NHS, governmental institutions, delivery services, and family back home all expect a UK number. A virtual number keeps you reachable without paying roaming fees or maintaining an old SIM. You can also have several phone numbers on a single device.
- International businesses entering the UK market. A UK phone number on your website signals local presence. Customers can call at local rates, while your team answers from anywhere in the world.
- Remote workers and freelancers. If your clients are based in the UK, a local number keeps communication simple and professional. Your clients don't have to think about international dialling codes or call costs.
- Online sellers and e-commerce stores. Marketplaces and customers trust sellers with a local contact number. A UK number on your website boosts buyer confidence.

FAQs
Can I receive SMS on a virtual UK number?
Yes. UK mobile (07) numbers support incoming SMS, which you can read in your personal account or the mobile app, receive by email or in messengers (Facebook Messenger, Telegram, Slack), or forward to your Teamsale CRM and other integrations - Pipedrive, HubSpot, Freshdesk, Odoo, and Zapier. Please note that the delivery of SMS sent from international numbers cannot be guaranteed, as it depends on third-party operators outside our control.
Can I use a virtual number for account verification (WhatsApp, banks, etc.)?
Virtual numbers work with many services, but some platforms might restrict verification via VoIP numbers.
Can I keep my existing UK number if I move abroad?
Yes, you can port your number to Zadarma and keep it active over the internet, without a UK SIM or roaming.
Does the number work without an internet connection?
The number itself operates in the cloud, so it's always active. To answer calls via an app or an IP phone you need an internet connection. Alternatively, you can set up call forwarding to a regular phone number.
How quickly is the number activated?
Most numbers are activated as soon as document verification is complete, usually the same day.
