Hi Nishit,
SMP is not mandatory for Fiori Client. You can also show a demo with a browsed on mobile device without Fiori Client.
If your need to build a custom Fiori Client, you can follow these documents.
- New Mobile App Configuration Service now available in SAP Mobile Secure
- Getting Started with Kapsel - SAP Fiori Client (SP09+)
