iMessage (Blue) -

  • iPhone to iPhone: requires internet (Either over WiFi or Cellular Service) as it is sent over internet protocol. Needs Activation on your device.
  • iPhone to Android: Not available



SMS/MMS (Green) -

  • iPhone to Android: does not require any internet it is sent over cellular voice protocol. Needs to be enabled by your Carrier for the SIM used by you.
  • iPhone to iPhone: When iMessage is not activated or the device is not connected to the internet either over cellular or WiFi



It will turn from Blue to Green if you have enabled "Send as SMS" and whenever your iPhone is not connected to the internet it is sent as SMS (green) to all iPhone users.
