Someone kicked me out the group chat.

Hey there najeeb53,

Great question, and one we'd like to help answer as best we can.

While we're not able to say the exact reason you were kicked out of a group chat, depending on the type of devices they're using, someone can add/remove someone from a group message. More details about this can be found in this link: Add and remove people in group text messages on your iPhone or iPad

If the ability to add you back to the group text message is available, it would need to be performed by the person in the group message chat as per the steps explained in the above link.

Cheers!
