Features

The private phone number app that does everything your real number does

SpareNumber is a private phone number app for iPhone and Android — a second, real number for calls, texts and voicemail that lives on the phone you already own. It works as a Wi-Fi calling app over any internet connection, gives you a virtual phone number you pick yourself, and keeps your personal number off every call and message you send.

Calling

Real calls, real quality

Calls connect over Wi-Fi or mobile data through carrier-grade voice infrastructure, so they land like any ordinary phone call. There is nothing for the other person to install and no username to exchange — you dial a normal number and their phone rings.

The in-call screen names the number you're calling from, so a second line never gets mixed up with your first, and keeps the controls where you expect them.

  • Works as a Wi-Fi calling app anywhere you have a connection
  • The person you call needs no app — their phone just rings
  • Mute, keypad and speaker, with a live timer on the call

Messaging

Texting that just works

Full SMS threads in the layout your thumbs already know: type, send, and watch the delivery ticks. Messages come back to your second number and stay in the app, with an unread badge on the Message tab so nothing sits unnoticed.

Because it's real SMS rather than app-to-app chat, it works with everyone — including the people who will never install anything.

  • Two-way SMS with anyone, no app needed on their side
  • Delivery status on each message you send
  • Threads are labelled with the number they belong to

Your number

A virtual phone number you actually choose

You aren't assigned whatever the system has spare. The picker lists real available numbers with the city and area code attached — New York (917), and so on — and you take the one you like. Search a digit pattern to narrow the list, or refresh it for a new batch.

Numbers are available in the United States, the United Kingdom and Canada today, with more countries coming soon.

  • Search digit patterns to find a number worth remembering
  • Every number is labelled with its area code and city
  • United States, United Kingdom and Canada, with more coming soon

History & voicemail

Every call accounted for

Recents splits your second line into three tabs — calls, missed, and voicemail — so a message you haven't heard never hides at the bottom of a mixed list. Your active number sits at the top of the screen, and each entry shows whether the call came in, went out, or was missed.

Callers the system doesn't like the look of are marked Potential Spam before you pick up.

  • Calls, missed calls and voicemail in their own tabs
  • Suspicious callers flagged as potential spam
  • Tap any entry for the full details of that call

Spam control

Block spam calls without touching your real line

Open any number from your recents and you get the whole picture: its country, the history you have with it, and one-tap actions to call, message, save it as a contact or share it.

The same screen is where you shut it down — block the caller, report them, or wipe the log. Spam that finds your second number never reaches your real one, because your real one was never in play.

  • Block a number straight from its call details screen
  • Report a caller who is abusive or fraudulent
  • Delete a call log entry when you want it gone

And the rest of it

Your real number, sealed

Outgoing calls and texts carry your SpareNumber. The person on the other end has no route back to your personal line.

No SIM, no second phone

Everything runs inside one app on the handset you already carry. Your existing SIM, number and plan are untouched.

Dial internationally

The keypad has a country selector built in, so calling a number abroad is the same three taps as calling one at home.

One app, two lines

Dialpad, messages, recents and settings sit in a single tab bar — your second line never spills into your first.

One thing SpareNumber isn't: a replacement for your regular phone service. It may not support emergency calls such as 911, 999 or 112 — keep your primary line for those. The details are in our Terms of Service.

Not sure how it all starts?

Three steps, about two minutes, and no second SIM anywhere in the process.
