Error: “The destination you are calling is not available in your calling plan”

 
A user may at times see this error when attempting to call a non-Silent Circle contact and often this is a non-Silent Circle number that is returning the error. Also, this often happens for users who are still on minute plans. Sometimes converting to a Monthly Subscription Credit Based plan will resolve the issue.
 
 
The reason you are not able to complete the call and receive the above error message is due to the high cost per call charged by certain service providers. Please see the link below to review if your contact is outside of our coverage areas.
