Basically Kone has chosen Vodafone to supply SIM cards to be embedded into Kone Lifts. I don't know how many Kone lifts are out there, but it is one of the largest manufacturers in the world so it must be in the millions.
Now the question is if NTC get involved? My guess is yes as this is the whole point of the relationship with Vodafone
