location sensor multiple providers

I've been told that for the best location results you want your network and gps providers enabled, is this correct? I created a IF statement: If:ContainText-LocationSensor.AvailableProvders. For  piece can I put gps and network? If one of these options were not available would it provide be location with other option, with out throwing error?



you only can have one provider and if possible, you should use gps for best results
