In Messages on an iPhone, blue bubbles mean the message was sent with iMessage, Apple’s messaging service for iPhone, iPad and Mac. Green bubbles mean it went as a regular text (SMS or MMS) or, on iOS 18 and later, as RCS when you message many Android phones. If your own messages or name appear blue, you’re simply using iMessage; nothing is wrong.
Quick Answer
Blue = iMessage (Apple devices, over the internet). Green = SMS/MMS or RCS (usually Android or when iMessage isn’t available).
What the Colors Mean
| Color | Sent with | Features |
|---|---|---|
| Blue | iMessage | Read receipts, typing indicators, effects, edits, high-quality media, end-to-end encryption |
| Green (text) | SMS/MMS through your carrier | Basic texts and small media |
| Green (RCS) | RCS on iOS 18 and later | Typing indicators, better media, read receipts; labeled “Text Message • RCS” |
Why a Message Turns Green
- The other person doesn’t use an Apple device.
- iMessage is off on either phone, or the other person signed out.
- No internet connection, and Send as Text Message is on, so it falls back to SMS.
Check Your iMessage Settings
- Open Settings > Apps > Messages (Settings > Messages on older iOS).
- Make sure iMessage is on.
- Tap Send & Receive to see which phone number and email you use.
- Turn RCS Messaging on or off under Text Messaging, if your carrier supports it.

Troubleshooting
- Messages to an iPhone user are green: Their iMessage may be off, or one of you lacks data. Try again on Wi-Fi.
- “Waiting for activation”: Check your connection and restart; activation can take up to 24 hours.
- Messages also appear on your iPad? See unlinking iPhone and iPad messages.
- Want pictures next to chats? See showing contact photos in Messages.
