 > The **GeoConvert** instance needs to access backend services to obtain information. Therefore, before performing the following steps, ensure that your device is connected to the network.
 
 1. Import the **geolocation** module by which you can implement all APIs related to the geocoding and reverse geocoding conversion capabilities.
