If your call isn’t going through, you’ll need to double check and see if one of the following common dialing errors isn’t being made:

Are your international calls being blocked?

Many phone service providers preset international calling to “blocked” so be sure this setting is off before trying to place an international call. It’s worth mentioning, however, that with Vonage World®, your calls to South Korea won’t ever be blocked.

Area codes + cell phone numbers = incorrect

Area codes can’t be added to international cell numbers. Also, numbers for cell phones usually have a set starting digit, one that isn’t not for use with landlines.

You don’t need that trunk code

In instances where the number you’re trying begins with a zero, drop it. The 0 is a “trunk code,” used in calls only to specific countries.


For example, if the number you are calling is 021 XXXX XXXX:

  • The wrong way to dial from the U.S. is 011 + 44 + 021 XXXX XXXX
  • The right way to dial from the U.S. is 011 + 44 + 21 XXXX XXXX

VoIP (Internet phone) connections

Most VoIP service providers won’t force you to dial 011 for an international call, including calls to South Korea. If this is the case, leave off the 011 U.S. exit code.
