Apps for iPhone like textplus?

Does anyone know any apps like textplus, where you can join different groups and talk to lots of different people?

Well if your'e looking to meet new people, I would recommend KikMessenger, which is an app where you create a username and can text random people who also have Kik. It's actually a lot of fun! Just don't use any personal information. You can add multiple people to one chat, I think. It's worth a try! You can also become "friends" with people you meet on it, or find some of your actual friends and chat with them, in a group if you want!
