Hello Bergietron10K,
Thanks for posting your question in Apple Support Communities.
To get started,
"There are three types of group messages that you might see: group iMessage, group MMS, and group SMS. The Messages app automatically chooses the type of group message to send based on settings, network connection, and carrier plan. For example:
• If you and your recipients are using Apple devices and iMessage is turned on, then the group message is sent as an iMessage.
• If you send a group message to people who aren't using iMessage, then the message is sent as an MMS or SMS message."
With that being said, can you tell us which type of group message you're referring to? Having this information will allow us to get a better understanding of the issue. Click here to find more info about the types of group text messages:
