Are you talking about "SAP Mobile Platform 3.0 SP03" ? if yes, SMP 3.0 actually doesn't require any license file because the SAP License Audit files are not in management cockpit. If you are licensed for SAP Mobile Platform(SMP) 3.0 you can download SMP 3.0 from SAP Service Market Place and install without any additional license file.
note: In a future release SMP 3.0 will run under the SAP Global license Auditing Services. Check SAP note 2044936
