Underlining text can help draw attention to certain words, phrases, or paragraphs that you want to emphasize. In this article, we will show you how to underline text on your iPhone with a few simple steps.

Step 1: Open the App With the Text to Underline

Before anything else, you need to open the app containing the text you want to underline. This can be any app that allows you to type in words, including Notes, Pages, or any email or messaging app.

Step 2: Highlight the Text You Want to Underline

Next, tap and hold down the text you want to underline until it becomes highlighted. You can then use the blue markers on either side to adjust the selection if necessary.
