Short message service (SMS) is a text-only text messaging service. When you get text-only text messages from your friend, those are SMS messages. When you open up a text with a meme, a selfie, or a dog photo attached, those are multimedia message service (MMS) messages. Even though MMS texts are usually more fun, TextChat live chat notifications are delivered to you instantly via SMS text notifications so that you’re connected with your live chat requests as quickly and smoothly as possible.
