There are many reasons why you might be changing the settings for the Messages app on your iPhone. Whether you want to stop sending read receipts or you want to stop your iPhone from deleting old text messages, there are a lot of different settings you can configure. One of the more confusing options, however, is the option for a subject field in your text messages.
You are probably familiar with the subject field when sending email messages, but it can be a little unfamiliar when dealing with text messages. Most text messages simply consist of a short message or image, and do not need a subject field. But some situations might dictate that you use a subject field, or some of your contacts might prefer it. If you elect to send a text message with a subject field, then it will look like the image below.
This was a message that I sent to myself, so you can see both how the subject field will look on your phone after you send it, plus you can see how it will look on your recipient’s phone. Note that the subject line is bold for both the sent and received messages. Additionally, the text message entry field is split, with the Subject field at the top of the text message field, and the Message field below it.
Turning the Subject Field On or Off in iOS 8
The steps in this will show you where to go on your iPhone to turn of the subject field in the Messages app. This guide was written using an iPhone 6 Plus, in iOS 8.
Step 1: Open the Settings menu.
Step 2: Scroll down and select the Messages option.
Step 3: Scroll down and tap the button to the right of Show Subject Field. You will know that the option is turned on when there is green shading around the button, as in the image below.
Note that the subject field is not a required field, even when it is turned on. You can still send text messages without a subject field, even if you have enabled the option using the steps above.
