You are out of mobile licenses: Field Service resource setup
Adding a mobile Field Service resource fails with a mobile-license availability message.

When this happens
Adding a mobile Field Service resource fails with a mobile-license availability message.
What to check
A service resource record and a licensed Salesforce user are different. Check license availability and assignments rather than deactivating unrelated resources.
Troubleshooting steps
- Go to Setup → Company Information and inspect available and assigned Field Service Mobile entitlements.
- Check the intended user’s permission set license and permission set assignments.
- If no entitlement is free, ask the administrator to review unused assignments and remove only those that are no longer required.
- Do not assume deactivating a service resource releases a user’s license. Verify the actual assignment.
- Use the learning org specified by the module. A general playground may not include the needed entitlements.
Verify the result
The intended user has the required license and access; resource setup and mobile access succeed.
