Get a second number, or as many you wish, and free business from private.

To get started, get some initial credit, and register your mobile number. It's simple, you can make calls within a minute and check out the app.

Calls on your second number go straight to one of your mobile or fixed-line phones. That's right, no internel calling, giving you the reliability of good old telephony.

When making calls, internet is used only in the first few seconds, with very little data. First, our system calls you. Then, when you answer, your contact will be called. Again reliable calls; because we know this is important for you.

You can contact us at Help > Chat With Us or Help > Send Email. You can also send us a message from our website. We always respond within a day.

When making calls, you'll typically use your second number as Caller ID. But the Caller ID can also be one of your mobile or fixed-line numbers you're registered in the app.

NumberBay is meant for people like you, that need reliable calls. As always, quality comes at a price. Simply because your calls run over real telephone connections (and not internet), both incoming and outgoing calls are charged from your credit.

The good news is that we've managed to keep prices very reasonable. For outgoing calls have a look at Credit > Call Rates. To keep things simple, all calls are charged per second. Also, to avoid surprises, you can see the per minute price of calls throughout the app.

We've started NumberBay to make advanced telephony features easy and accessible. When dealing with telecom companies as customers, we've always hated the unclarity of bundles and hidden costs. We want our service to be fair and free from dirty tricks.

Enjoy NumberBay!
