What's the Difference Between an iMessage and SMS (Text Message)

  • Text messages are sent through your cellular data provider (Verizon, AT&T, Sprint, etc), but iMessages are automatically routed through Apple’s servers, saving you data if you’re on Wi-Fi.
  • If you aren’t connected to Wi-Fi, the message will count towards your monthly data plan. But if you are connected to Wi-Fi, the iMessage will be sent freely and won't count towards your data plan.
  • Since you can send iMessages using Wi-Fi alone, you can also send iMessages from your iPad or Mac computer.
  • You can visually recognize the difference between an SMS (text message) and iMessage by the color of the message bubble. iMessages send as blue while text messages send as green.

The caveat: the person you’re speaking to must also have an iPhone in order for iMessage to work. If they don’t, the message will send as a text message.

How to Turn on iMessage on iPhone or iPad

  • Open Settings.
  • Tap Messages.
  • Toggle on iMessage.

It’s also a good idea to check your Wi-Fi connection. Remember that iMessages sent over Wi-Fi don’t cost a thing, but iMessages will use your data plan if it needs to. To check your Wi-Fi after or before turning on iMessage,

  • Open Settings.
  • Tap Wi-Fi.
  • Make sure Wi-Fi is toggled on at the top and a connection is checked off, meaning you’re using it.

You’re ready to begin sending iMessages to other friends on their iPhone, iPad, or Mac. You’ll know you’ve successfully sent an iMessage if your outgoing message is blue.

How to Turn Off Read Receipts

When turned on, Read receipts lets the person who sent you messages know when you have seen them. Some people like having this on because it lets others know that they aren’t not replying, they just haven’t checked their messages in a while. However a lot of people find this feature annoying. Luckily, you can easily turn Read receipts off. To do this,

  • Open Settings.
  • Tap Messages.
  • Find Send Read Receipts. Toggle it off.

That’s it! Conversely, if you'd like to turn Read receipts on, simply toggle Send Read Recipts to the on position.
