RingCentral text messaging requirements ======================================= The RingCentral app on your mobile, desktop, or web browser and the standalone RingCentral Phone app allow you to send and receive SMS, MMS, Group SMS, and SMS Broadcast messages within RingCentral and other carriers. Note: * **Short Messaging Service (SMS)** , commonly known as text messaging, is when a text message is sent to one or more recipients (not as a group). Messages are billed per segment, with a maximum of ten segments for each SMS. Refer to [RingCentral character limits for texting](https://support.ringcentral.com/article-v2/Character-limits-for-text-messages.html?brand=RingCentral&product=MVP&language=en_US#:~:text=If%20you%20send%20one%20message,be%20billed%20for%20three%20segments. "") for more details. * **Multimedia Messaging Service (MMS)** supports text messages with attachments, such as videos, images, and audio files. Refer to the [supported media file types](#supported-file-attachments "") for more details. * **Group SMS**, also known as group texting or group messaging, is a text message sent to two or more recipients as a closed group. These messages become a group chat or group conversation and are typically sent as MMS. A maximum of ten recipients is allowed for each Group SMS. * **SMS Broadcast** is a one-to-many SMS messaging service where individual (non-group) text messages are sent to multiple recipients simultaneously. Each recipient receives the message separately, without forming a group conversation. The RingCentral app supports SMS Broadcast to a maximum of 100 recipients.
