How do I send a group chat on the Passport?

Everytime i try to send or start a group chat, its never a group chat and its like sending individual text to multiple people

I am not sure why group chat is like an advanced technology for blackberry

But anyone knows how to start or send group chats?

Thanks...i am using the blackberry passport

When you added the recipients of your message did you enable group conversation? Is right under the names/numbers of your recipients
