Can I really make business calls on my own mobile?
Yes—with a Rinkel business number, business calling works on the iOS or Android phone you already own. You download the Rinkel app, connect your business number, and from that moment you can make and take business calls. Your personal number keeps working alongside it for personal calls.
Do I need an extra SIM for business calls on my mobile?
No, you don't need an extra SIM. No physical SIM, no eSIM. The Rinkel app uses the mobile network your phone already runs on and routes your business calls over that network. That saves you money and skips the faff of a second SIM.
What's the difference between a second SIM and business calls through Rinkel?
A second SIM (physical or eSIM) needs a dual-SIM phone, a separate telecoms plan and its own settings. With Rinkel you get a business number through an app, on your existing phone, with no hardware changes. Cheaper, quicker to set up, and it works on any mobile.
Does this work abroad too?
Yes. Your Rinkel number works abroad too: you can call to over 50 destinations at the same rate, as long as you've got mobile signal. No roaming surcharge on your business calls.
Can I bring my existing business number to Rinkel?
Yes. With number porting you move your current business number to Rinkel free of charge. You stay reachable during the switch. Got an 03 national number or a regional number? They can all come with you.
What do business calls on your mobile cost with Rinkel?
You can make business calls on your own mobile from £7.99 per user per month. No purchase costs, no installation fees and no multi-year contract. You get 50% off your first month, and pay annually to save another 10%. Not happy within 30 days? You'll get your money back.
Does this work with multiple colleagues too?
Yes. You add colleagues to your Rinkel plan whenever you like. Each colleague installs the app on their own mobile and gets their own settings. You pay per user per month, so your plan scales with your team.
Do business calls through Rinkel use VoIP?
No. The Rinkel app uses your phone's mobile network (4G/5G), not your wifi internet like classic VoIP apps. That means your calls sound as clear and reliable as calls on your personal number—even when you've no internet.
