In the US, iMessage is the most important app for lock-in. I wonder how much of the reason for lower iPhone market share outside the US is down to the fact iMessage is far less widely used by Apple users, who instead use cross platform apps like WhatsApp or Facebook messenger. It's hard to untangle cause and effect, but I do see a lot of iPhone users saying that iMessage is what prevents them from switching. The stigma of the green bubble is real.
