Can Android phones participate in group texts with iPhones?

So, IIm planning on converting from iPhone to Android, but I still want to be able to participate in group chats with my friends.

Not with proprietary SW. You'd all need to be using a third-party app.

I don't see why not. They are phones at the end of the day.

Not with imessage, I like the way imessage does group chats but other phones don't have that.

If its with sms or a online messenger then yes. As long as its nothing exclusive to iPhone such as Imessage.
