Have you ever noticed that some of your iMessages are shown in a green bubble while others are displayed in a blue bubble? These different colored bubbles actually represent the two types of messages you can send on an iPhone: iMessages and SMS messages.
iMessages are sent between Apple devices using a Wi-Fi or cellular data connection, and they appear in a blue bubble. They support features like read receipts, typing indicators, and the ability to send photos, videos, and other multimedia content. On the other hand, SMS messages are traditional text messages that are sent over the cellular network, and they appear in a green bubble. They do not support the same advanced features as iMessages, but they can be sent to any phone, not just Apple devices.
So next time you see a green or blue message bubble, you’ll know the difference between an iMessage and an SMS message.
