Hi, I am new to RaceChrono and have acquired a Samsung Galaxy S5 android phone to use with RaceChrono. I already have a Dual XGPS 160 device to use to pair for the GPS service. My question is this - will the phone use data (ie. sim card data - 4G) when being used with RaceChrono. I ask because I am only using this phone for RaceChrono - in Australia you cannot get pre-paid data only sim cards for use with smartphones, they all have phone service also connected. So I need to work out how much data RaceChrono will or wont use when on the track. I don't want to have to spend much on a sim card if it doesn't use much or any data. Hopefully it wouldn't use any and would just operate through the separate GPS device? Software updates for RaceChrono etc can be easily achieved when the phone is connected to a wireless network.
Any info would be greatly appreciated.
