Chat with iPhone users?

[Snikrz]

Just got my galaxy s4 and I was wondering if I could use the stock messaging app to stay in an ongoing group message with some friends that use iPhones? I haven't receive and messages yet from the group and my friend told me there was some texts going on.

I used iMessage with my cousin and friends, but since I went Android I convinced them to use WhatsApp.
