# SVC067 - Guiding by IMSI, call start time is before service's effective date minus
      grace

Override **NOT** allowed

| Name | Guiding by IMSI, call start time is before service's effective date minus grace. |
| --- | --- |
| Common Cause | The call start time of this usage record is before the effective date of the service. |
| Common Resolution(s) | Actions you can take to resolve the problem: - Change the effective date of the service to be earlier so this usage will bill to this service. - If start grace doesn’t reach back far enough, consider changing the start grace setting in Admin Console. |
| Details | Each service has an effective date and a disconnect date. The call start time of each usage record billed to a service must fall between these dates (actually there is a start grace period setting that extends the start date to be even earlier by a number of days, so that usage such as this can load). In this case the usage is dated before the effective date of the service (including the start grace period). |
