Frequently Asked Questions
5 questions
When an iPhone user texts an Android device that doesn't support iMessage, the message falls back to SMS (Short Message Service), which is unencrypted and limited to 160 characters. iMessage displays these conversations with a green bubble to indicate SMS rather than iMessage (blue bubble). This is a technical limitation, not a feature.
