Get started How it works

A second number alongside your personal phone: how does it work?

A second number with Rinkel works differently from a second SIM or a second handset. No physical change to your phone, no extra hardware. You download the Rinkel app, pick a business number (a national 03, a regional number or an international one), and your second number is live on your existing mobile within three minutes.

Your personal number keeps working for personal calls. Someone rings your business number? You'll see straight away that it's a business call, and you pick up. And when you call out through the app, your customer always sees your business number—never your personal one.

Choose your business number

Why a second phone number?

Four reasons entrepreneurs and small business owners actually give:

Work and personal, kept apart. Customers ring your business number; friends and family ring your personal one.
A more professional look. A proper business number—a national 0330 or a regional number—lands differently from a mobile. Customers clock it as a business straight away.
No second phone to lug around. No spare handset in your bag, no second charger. One phone, two separate worlds.
Tax-deductible. A business phone plan is a genuine business expense, so you can reclaim the VAT through your return.

No waiting around, no engineer visit. You set up your second number yourself, from your desk chair:

Frequently asked questions about a second phone number

How do I get a second phone number on my mobile?

You get a second number with Rinkel in three steps: choose your business number (a national 03, regional or international), download the Rinkel app on your mobile, and your second number is live within three minutes. No second SIM, no eSIM, no second handset.

What does a second phone number cost?

A second business number with Rinkel starts from £7.99 per user per month. Your first number comes free with your plan. Plus 50% off your first month, and 10% off when you pay yearly. Not happy within 30 days? You'll get your money back.

What's the difference between a second phone number and a second SIM?

A second SIM (physical or eSIM) is a separate SIM in your handset. It needs its own plan with a telecoms provider and a dual-SIM phone to run it. A second number with Rinkel works through an app on your existing mobile—no extra SIM, no dual-SIM handset. Simpler, cheaper, and it works on any smartphone.

Does a second phone number work on any mobile?

Yes. The Rinkel app works on any iPhone or Android phone. No specific handset needed, no dual-SIM, no eSIM support. Got a working smartphone with internet or mobile data? Then your second number works.

Can I use my existing business number as my second number?

Yes. With number porting you move your existing business number over to Rinkel free of charge—whether it's a national, regional or international number. You stay reachable throughout the switch. (One thing to note: Rinkel ports landline numbers, not mobile numbers.)
