What’s the difference between a text message and iMessage?

To answer this question, let’s first look at a typical text message.  When someone sends a text message, they type a message on their phone and hit the send button.  At that point, the cellular data service provider (Verizon, AT&T, Sprint, or whoever) transfers that message through their network to the recipient.  Depending on your cell phone plan, you could be charged for the text message (if you don’t have an unlimited texting plan or if you exceeded your texting limit for the month).  Additionally, if you send photos or video, the data you sent counts toward your monthly data limit on your data plan.  While sending a few pictures in a text message may not seem significant, a teenager’s diet of sending hordes of pictures and videos can add up.

Enter iMessage.

When you send a text message to someone that has an Apple ID, the Messages app automatically recognizes that person’s Apple ID and routes the message through Apple’s servers instead of using the cell phone carrier.  This is done automatically and avoids any texting charges from the cell phone carrier. Sending iMessages will still use cellular data when the iPhone is not connected to a Wi-Fi network. Users that approach the monthly limit of their cellular data plan may opt to turn off iMessages. Since iMessages can be sent using a Wi-Fi network, they can be sent from an iPad or iPod touch that has no cellular data connection.

 

The Messages app provides some visual indication as to whether you will be sending an iMessage or a regular text message.  In the figures below, the one on the left shows the Messages app when you are sending an iMessage.  The figure on the right shows the Messages app when sending a regular text message.

Notice the iMessage has a blue Send button and the text entry field displays the word iMessage.  When sending a regular text message, the Send button is green and “Text Message” is displayed in the text entry field.

Occasionally, you may notice iMessages are being sent as regular SMS text messages. This article describes why iMessages are sent as SMS text messages and how to avoid it.
