Hi Abu,

Please check below sample code: 
string phn = '8234567891';
        if(phn.length() == 10 && (phn.startsWith('9') || phn.startsWith('8') || phn.startsWith('7'))){
            system.debug('Phone nember stated with 7 or 8 or 9');
			//insert st;
        }
        else{
		 system.debug('Phone nember not stated with 7 or 8 or 9');
           // ApexPages.addmessage(new ApexPages.message(ApexPages.severity.WARNING,'Your Phone number should have Only 10 digits not more //than that or lesser then that .'));
        }
