You may have observed that certain iPhone messages are green while texting your buddies and loved ones
When you send text messages from your iPhone to a classmate, loved one, or coworker, the message may turn green. The colour represents the method you have utilized and, in some cases, the type of device to which you are sending.
Green Message Background
If the background of your message is green, then it was sent or received through SMS transmitted via your cellular provider. The message was also transferred from a non-iOS phone, such as a Windows or Android phone
In addition to standard text messages, green text messages can be sent or received to an iOS smartphone. When a device’s iMessage is switched off, a green text message can also occur.
Go to your iPhone Settings (gear icon) and then to Messages to see if iMessage is enabled or disabled. Ensure you enable iMessage.
Blue Message Background
If your text message has a blue background, it implies that the message was sent using iMessage and that you sent or received it from another iOS device.
About the iMessage platform
iMessage is a free messaging service that works with all iOS devices, including the iPhone, iPad, iPod touch, iMac, MacBook, MacBook Air, MacBook Pro, and others. Apple created iMessage, which is compatible with all Apple products but not with non-Apple devices. It also asks that you use your Apple ID to log in. If you have an iPhone but aren’t logged in with your Apple ID, you won’t be able to use iMessage.
For typical communications, iMessage does not use the data limits set by your network carrier. iMessage is a free and quick messaging service. When chatting with another iPhone or iOS user, iMessage is a good choice.
Text message charges do not apply to iMessage. No mobile coverage is necessary to send an iMessage because it may be sent over WiFi. It’s also possible to send it using your cell phone provider (AT&T, T-Mobile, Verizon, Sprint, etc.)
