I'm not claiming a source, I'm pointing out the obvious implications of their actions in the space. The original ipad data plan isn't something AT&T thought up, it's something Steve forced on them and it's still the closest thing we have to dumb pipes. IMessage was another end run around carrier cash cows. Multi-SIM is another step. And when this choice Sim goes global that will be another bullshit carrier ripoff we can wave goodbye to.
