Recommandations :  

  • The use of the live tracking and emergency module functions requires a subscription to the local telephone network with the possibility of sending data (local SIM card). 
  • Battery and autonomy of the phone : GPS tracking and live tracking functions engage the battery of the phone. In order to save your battery, 3 recommendations :
    • Cut cellular data from the other apps during the race;

    • Take an external battery in your bag to charge your smartphone when needed !
