how do i create a group text on my iPhone 14 Pro Max

What type of group message do you want to create?

Types of group text messages

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. You need to activate 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. You need to contact your Carrier to enable SMS and/or MMS.
