Thank you Guys.

My common Provider File:

reverseGeocode(lat: number, lng: number): Promise<any> {
    return new Promise((resolve, reject) => {
      this.nativeGeocoder.reverseGeocode(lat, lng)
        .then((result: NativeGeocoderReverseResult) => {
          let str: string = `The reverseGeocode address is ${result.countryName} in ${result.countryCode}`;
          resolve(str);
        })
        .catch((error: any) => {
          reject(error);
        });
    });
  }

My Main Class file:-

this.watch = this.geo.watchAndLocate().subscribe(position => {
      this.zone.run(() => {
        this.lat = position.coords.latitude;
        this.long = position.coords.longitude;
        this.latt = position.coords.altitude;
        this.accu = position.coords.accuracy;
        this.geo.reverseGeocode(this.lat, this.long).then(res => {
          this.zone.run(() => {
            // alert(res.countryCode);
            this.country = res.countryName;
            alert(this.country);
          });
        })
      });
    })
