Do I need to buy a number for a second line?

Only if you want to receive calls. Outgoing calls work with no number of your own. A US or Canada number for inbound costs about $2.14 to $5 per month.

Where does the second line live?

In your browser. You make and receive calls from any device with Chrome, Safari, Edge, or Firefox, with no app and no second SIM.

How much are outgoing calls on the second line?

Per minute with no monthly plan, such as about $0.046 per minute for the US, plus a small $0.004 connection fee per call. The first call is free.

Can I keep this separate from my personal number?

Yes. The digital number is fully separate, so you can use it as a work or side line without giving out your main mobile.

Does the second line cost anything if I only make calls?

No standing cost. The monthly number fee is only for receiving calls. If you just make calls, you pay only the per minute rate, with no monthly fee.

Do I need a second phone or SIM for this?

No. The line lives in your browser on the device you already use, so there is no second handset and no second SIM to manage.

A separate line without a second phone

A second phone line keeps work and personal calls apart, or gives you a number to share without handing out your personal one. StartACall gives you that line inside the browser, with no extra device and no second SIM.

For outgoing calls you do not even need a number of your own. You open the browser, dial, and reach any landline or mobile worldwide.

Add a number to receive calls

If you want people to call you back, you can buy a US or Canada digital number for about $2.14 to $5 per month. Incoming calls then ring in your browser, so the second line both makes and receives calls.

You can give that number out as your work or side line, keeping it fully separate from your main mobile number.

Pricing for the second line

The monthly number fee covers receiving calls. Outgoing calls are billed separately at a per minute rate, such as about $0.046 per minute for the US, with a small $0.004 connection fee per call.

Your first outgoing call is free with no credit card, and any calling credit you add never expires. There is no monthly plan beyond the optional number fee.

Keeping work and personal calls apart

Using one number for everything mixes clients, sellers, and personal contacts into the same call log and the same caller ID. A separate browser line lets you publish a work or side business number that is not tied to your personal mobile, so you can put it on a listing, a card, or a profile without exposing your private line.

Because the second line lives in the browser, you can step away from it. Close the tab at the end of the day and your personal phone is unaffected, which is a simple way to keep some separation between work hours and the rest of your time.

Choosing your inbound number

The inbound number is a US or Canada digital number, so you can pick an area code that fits where your contacts are, such as a 212 for New York or a 415 for the Bay Area. To callers it looks like an ordinary local number, and they dial it the same way they would any other.

The monthly fee of about $2.14 to $5 is the only standing cost, and it is entirely optional. If you only ever need to make calls, you skip the number and pay nothing each month, just the per minute rate when you actually call.

A second line without a second device

Carrying two phones, or swapping SIMs, is the old way to keep a separate number. The browser line removes that entirely. The same laptop or phone you already use becomes the second line whenever you open the StartACall tab, with no extra hardware and no second SIM tray.

It also means the second line is available on whichever device you happen to be on. Sign in on a work laptop during the day and your phone in the evening, and the same line, credit, and inbound number follow you, so your work or side number is always within reach.
