Ever receive a text from someone that was mysteriously cut off at the end, only for the rest to appear later in a separate text—or worse yet, receive the end of a text before the beginning? That happens when you run over the limit of 160 characters that some carriers use to keep SMS messages small. For iPhone owners using iOS 4 or later, there’s a simple way to ensure that you won’t be joining the broken text crowd. Open the Settings app, tap on Messages, and make sure that the slider for Character Count is turned on—and that’s it. Once you hit 30 characters when composing a message, a counter will appear overtop the Send button, letting you see how many characters you’ve used, and thus letting you figure out how many you have left.
