Maybe, maybe not. You really dont know when sending sms.I still have no idea what anybody's point is in this thread.
I'm an iPhone user, as is my wife. The iPhone's text app is named Messages. Because we're both iPhone users, the messages are sent as iMessages..
My boss and work partner have Androids. We use group texts to communicate with no issue. Guess what, I use the Messages app and I can talk to Android people. I'm not locked to a platform or whatever.
I talk to a friend in Canada regularly, I don't know what type of phone they have, but the dreaded green bubbles don't stop the messages coming in. Messages app works fine and nobody's been extorted to buy an iPhone.
For all you know the android guy using sms might actually be 10 messages behind everyone else and the conversation is out of order. With internet messaging everyone sees the same screen pretty much, the same way this thread will appear the same for everyone on GAF.
Whatsapp takes it even further. Check for sent, double check for delivered, double check in blue for message read.
