Disabling iMessage so can receive SMS on Android when switching from iPhone
Joyce Park stashed this in Switching away from Apple
Even the most well-designed, comfortable vendor lock-in is still vendor lock-in.
I moved from iPhone (Sprint) to Android (Verizon) three days ago and still haven't been able to get texts reliably from my iPhone friends. This is how to fix that.
It took us two days to figure out that the texts I was sending were being captured by iMessage and never got through to the SMS on the new Android phone. Bad Apple!
