How do international calls work with a Mobile Vikings for Business subscription?

International calls are not included in your employee's subscription bundle and are therefore charged extra. The exact rates can be found here.
Note: by default, these extra costs are charged to the employee. You can adjust this by setting a monthly out-of-bundle allowance for your employee. This fee can partially or fully cover costs outside the normal subscription bundle. As an employer, you adjust this allowance via My Business, where you manage the subscriptions of your employees.
