Do I need a phone number to make outbound calls?

No. You can place outbound calls directly through StartACall without purchasing a dedicated phone number.

Can people call me back?

Yes. To receive inbound calls directly in your browser, you must purchase a unique US or Canada digital number, available for $2.14 to $5/month.

What does 011 mean when dialing a phone number?

011 is the international access code, also called the exit code, for the US and Canada. Dialing it before a country code routes your call out of the North American network to a foreign destination.

What comes after 011 when I dial?

After 011 you dial the country code, then the area or city code, then the local number. Drop any leading 0 from the local number, since that digit is only used for calls placed inside that country.

Can I use a plus sign instead of 011?

Yes. On most mobile phones a plus sign replaces 011, because the network converts it to the correct exit code. The plus format is reliable whether you dial from the US, Canada, or while traveling.

How do I make an international call without dialing 011 at all?

Use StartACall in your web browser. You select the country and enter the number, and the call connects over the internet with no exit code, no SIM, and pay as you go per minute billing.

Dial the Exit Code

Country Code

After 011 dial the country calling code. Examples: 44 for the United Kingdom, 91 for India, 61 for Australia, 49 for Germany.
