ps The proposal includes the use of multiple ICE’s by naming them ‘ICE1’, ‘ICE2’ or ‘ICE Thuis’, ‘ICE Ouders’.
Tip, if your phone complains about the ‘double entry’ because your ICE person is already in the phonebook, put a * (star) behind the number in your phonebook, this doesn’t inflict during dialing and most phones will see this as a difference so you don’t see ‘ICE’ if you called by that person.
