Why are my iPhone messages green? What SMS green texts mean and how to get blue iMessages

• If your iPhone messages are green, it means they’re being sent as SMS texts rather than iMessages.
• You’ll always see green when texting Android users, or when you’re not connected to the internet.
• If all of your iPhone messages are green, you should make sure iMessage is turned on in Settings.

You may have noticed that the text messages in your iPhone’s Messages app can appear as either green or blue. 

The difference? Green messages are ordinary SMS text messages, while blue messages are using Apple’s proprietary iMessage format. If you’re used to seeing blue iMessage text bubbles but they are suddenly green, it can be an indication you’ve been blocked – but that’s just one possibility, and isn’t necessarily the most likely.  

Here’s everything you need to know about why your iPhone is sending green messages, and how to fix it if you think it’s a mistake.

The difference between SMS and iMessage, explained

Ordinary SMS text messages are sent using your cellular voice service, and don’t use the internet or your data plan. All mobile phones — Android, iPhone, and otherwise — can use SMS. 

iPhones have an additional option, though. By default, iPhones send and receive iMessages between other Apple devices. iMessage was built to send messages over the internet, using Wi-Fi or your cellular data plan. 

When sending messages to another Apple device, your iPhone will use iMessages. But if you’re texting an Android phone, or you’re not connected to the internet, your iPhone will use SMS. As a general rule, you can’t send an iMessage to an Android phone.

But while iMessages are limited to Apple devices, they have a number of advantages over SMS. 

• iMessages don’t count against your texting plan — instead, they use Wi-Fi or your data plan, depending upon whatever’s available when you send or receive the message. 
• The Messages app shows pulsing dots when someone is writing an iMessage to you
• iMessages can contain information that SMS does not, such as your location. 
• You can enable notifications for iMessages, showing what has been delivered and read.

How to enable iMessage on your iPhone if it’s turned off

The bottom line is that iMessage is generally better than SMS, and your iPhone will use it whenever possible — you don’t have to do anything special to send an iMessage to another Apple device, aside from having iMessage turned on. 

Here’s how to make sure iMessage is turned on:

1. Start the Settings app.

2. Tap Messages.

3. Make sure iMessage is turned on by swiping the button to the right.

How to enable SMS only on iPhone

It’s possible to disable iMessage entirely, which ensures that all your messages are sent as SMS using your cellular service’s voice network instead of Wi-Fi or your data service. You may want to switch to SMS if there are issues with Apple’s messaging system, or if you have an urgent message to send, but you can’t find a stable internet connection.

If you do this, all texts – sent to both iPhone and Android devices alike – will appear in green text bubbles.

Here’s how to switch to SMS only:

1. Start the Settings app.

2. Tap Messages.

3. Make sure iMessage is turned off by swiping the button to the left.
