A friend of mine send me email a couple of days ago noting that there is a problem in sending emoji from a Verizon iPhone to an AT&T iPhone. “Emoji” is a japanese term for graphical picture characters sent in text messages. The word literally means “picture letter.” U.S. iPhones do not natively support its extended character format. However, there are apps to allow its use.
This discussion thread in Apple’s discussions area for the CDMA (Verizon) iPhone 4 sheds light on the issue.
Verizon [.] does not transmit UTF8 characters (extended/foreign characters and emoji) outside the Verizon network. AT&T, however, does pass UTF8 characters to other networks. So…
AT&T iPhones can send emoji to AT&T iPhones and Verizon iPhones.
Verizon iPhones can send emoji only to other Verizon iPhones.
