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.

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.
