Put your best foot forward with a UK-wide business line. Professional, customisable, and yours in minutes.
03 business numbers are UK-wide numbers that don’t tie you to a specific location. They’re great for UK businesses and entrepreneurs wanting a nationwide presence despite being based in one place.
With Rinkel, your 03 number comes with a suite of business features. From setting business hours to capturing call recordings, Rinkel gives you a hassle-free way to manage your business phone and features.
Your business needs a professional line for customers to contact. Without it, they’re reaching your mobile and being greeted with “Hey, who’s this?” It’s not the first impression you want to give.
Nationwide numbers make your business more trustworthy across the UK. Your client might be calling your Nottingham-based business from Newcastle, but they don’t need to know that.
Give customers an experience they can trust from the get-go. If you’re a UK business looking to grow your presence and professionalism, Rinkel paves the way without the complicated setup and hefty price tag.

With Rinkel, your business line plans come jam-packed with phonetastic features:
Rinkel works on the phone you already use. No sim-swapping and no second devices, just a business line that slots straight into your everyday.
Unlike other business phone systems, Rinkel’s company phone lines use mobile networks to connect you to your customers. It’s the reliability your clients expect, and doesn’t involve connecting to risky public WiFi or depending on your mobile data.
It’s speedy, simple, and reliable. And that’s what growing businesses need.
What you see is what you get with Rinkel. No lengthy contracts locking you down, no hidden fees funneling profits out of your pockets; just transparent, flexible plans for your business line.
First number for free with your subscription. 10% discount on Yearly subscriptions.
You’ve got enough on your plate without stressing about getting your business phone number up and ringing.
It’s the professional phone solution that connects you with your customers without hassle or hang-ups.

Smart and stylish solution! I've tried a few calling apps, but this one hits the sweet spot between functionality and good design. Worth every penny.
Timothy HunterWay more professional than what I had before. I needed a UK number to appeal to UK clients and this app helped me with that main problem I had.. I use the personalised voice mail feature on the weekends which I recommend for anyone that needs the break like me :P
Jessie RosyLiterally had my business number set up in minutes. So happy to finally find an app for where I'm at with my business atm, everything else on the market was way too expensive or complicated.
Lizzie KaraNo fluff, no confusing menus, just a simple app. Honestly one of the best designed small business tools I’ve found.

03 numbers are UK phone numbers that aren’t linked to anywhere specific. Instead of showing up as “Calling from Manchester” or “Calling from Belfast,” non-geographic landline numbers give businesses, public services, and charities a national presence that doesn’t tie them to a town or city.
The cost of a 03 number depends on the provider you’re purchasing it from. Rinkel plans start at £7.99 per month. You get your 03 number included in your subscription, plus plenty of helpful business phone features—like call recording, business hours and caller queues.

You can use Rinkel on your mobile phone or desktop (via My Rinkel, our Customer Portal). You can choose where incoming calls arrive in your profile settings.
Outgoing calls with Rinkel are also simple. The in-app dial screen resembles your smartphone's native dial screen, so it’s something you’re already familiar with. To make a call with Rinkel, enter the app and dial the number (or select from your contacts). You’ll immediately receive an incoming call, which—when picked up—will start your outgoing call.
You receive incoming business calls as you do every other call. Your phone rings, and you pick it up. Rinkel offers three options to help ascertain when you’re receiving a business call:
No, Rinkel uses your existing provider’s network on mobile—which is typically a stronger and more reliable VoIP alternative. You’re not dependent on an internet connection, and instead rely on the thousands of cellular towers dotted across the UK. This means high quality audio across more of the country—what’s not to like?
The only time you’ll be using VoIP technology is when making and taking calls on the My Rinkel desktop portal. Typically, this means you’ll be connected to your home or office WiFi, meaning you’ll be using your chosen internet provider for calls.
