If there was one that could make a phone call, I would leave it at home. I carry my cell on bike rides, but to ascertain that I am not bothered by it I leave it in airplane mode. I only carry it for emergencies.
I can only think of one reason to put an active sim card on your bike, for a tracking device if the bike is stolen. I think that would make sense for some people.
