Who it's for

One more number. A lot less hassle.

Work from home

Give clients and colleagues a dedicated work line, not your personal mobile. It rings your phone through the day, and you can mute it after hours. Switch off properly at six.

Run a business or side hustle

Put a proper UK number on your van, your flyers or your Google listing, even a local landline-style one that says “established business.” Keep your private number private, run a separate WhatsApp Business on it, and keep the line even if you switch SIM.

Healthcare & care workers

Contacting patients or clients while you're out and about? A nothanumber gives you a work line in your pocket instead of handing out your personal mobile, and you can switch it off the moment you're off shift.

Buy & sell online

Selling on Marketplace, Vinted, eBay or Gumtree? Put a nothanumber on the listing instead of your personal mobile, so your real number never goes public; keep every buyer message in one tidy inbox.

Dating & meeting people

Have a real conversation on a nothanumber before you share your personal number. A separate line for meeting new people, kept safely apart from your everyday one.

Teachers

Calling a parent or carer? Use a nothanumber instead of your personal mobile, so home and school stay separate. It's a work line that lives in your pocket, and you can switch it off the moment the school day ends.

Questions

Second number questions, answered

What is nothanumber?

nothanumber is a second phone number app for the UK. It gives you an extra UK mobile or landline number that lives inside one app on the phone you already own - no second SIM and no second handset required.

Can I get a second UK mobile or landline number?

Yes. You can choose a genuine UK mobile number or a landline-style geographic number and use it alongside your existing one, all from within the app.

Do I need a second SIM or a second phone?

No. Your nothanumber works inside the app on the phone you already have. There's nothing to put in your SIM tray and no extra device to carry.

Can I make and receive calls and texts?

Yes. You can make and receive both calls and SMS directly from within the app, on your second number, using your phone's normal speaker and microphone.

Will my personal number stay private?

Yes. You can hand out your nothanumber instead of your personal one - for work, selling online, dating or sign-ups - and keep your real number to yourself.

How does billing work?

You top up a wallet and pay as you go, so there's no long contract to forget about. You only pay for what you use.
