Hello @tohid, welcome to the MindSphere Community.
Unfortunately, we currently do not offer a trial or test access to MindSphere since we are yet in a beta stadium. However, I could offer to connect you to our team which can lead you through a demo and show it to you in real time. If you are interested in a personal presentation, just let me know either here or via private message and I will set up the contact.
Furthermore, will I update the community here and on our Blog as soon as we have more information regarding a trial system.
