A customer is reporting an issue when provisioning devices through zero-touch. By following the problem-solving framework, you have concluded that the core issue is related to the IMEIs. Whom would you contact to help resolve this?

The reseller or carrier is responsible for uploading device IMEIs to the zero-touch enrollment portal. If there are issues with device provisioning via zero-touch related to IMEIs, it indicates a problem with this upload or the data itself. The EMM (Enterprise Mobility Management) provider manages the device policies and configurations, not the initial device registration. The OEM (Original Equipment Manufacturer) manufactures the device but doesn't handle the zero-touch enrollment data directly for specific customers. The customer's procurement team orders the devices but doesn't manage the technical zero-touch enrollment portal entries.
