Hello Vishnupriya,
as Kimmo already described, there is no (official) support at the moment for Windows Phone, especially for the sap.m library. But there is support for Windows 8(.1), for example on the Surface devices of Microsoft.
For more information please have a look to the paragraph of the UI5 developer guide (https://sapui5.hana.ondemand.com/sdk/#docs/guide/91f079dc6f4d1014b6dd926db0e91070.html).
Regards,
Florian
