Unfortunately you cannot.
Your mobile will be put in a sealed enveloppe and must remain this way. You also need to switch your phone off to make sure your battery remains ok when you need to make the abandon call.
You will receive an emmergency contact number to give to the homefront.
Then if really necessary, the organisation can be contacted via that number.
Control Center knows where you are by checking the tracker.
The closest Security Assistent will come to you (if you are not too deep in the forrest) and inform you of the emminent situation.
Then you can decide to break the seal of the mobile phone and call home. This means a direct DNF (did not finish).
The Security Assistent will bring you back to your car.
