What percentage of Americans do you think use a custom app to replace texting entirely?
Here's what we know:
32% don't off the bat (iMessage is the only supported texter on iPhone)
the other 68% are android users. Now, unless 50% of Android users use a custom act like Signal or Facebook messenger to complete replace texting, iMessage is the dominant messenger in North America.
It's also the only one that really sells a device. People stay on iPhone because they want to keep iMessage.
Make a counter argument. North American isn't China. We use Facebook Messenger, Snapchat, and Whatsapp here and there, but by and large we text using the default, and for one in three of us that's iMessage
