I just got a Star N9300 phone and activated it with Ultra Mobile Service. I tried texting some short codes on it but keep getting the message: Free Msg: Unable to send message - Message Blocking is active. Text messaging to regular phone numbers works fine though. I called Ultra's support and they said that they block short code messages. They did not offer to unblock the messages so I'm stuck. Is there a way I can get around this by programming my phone or a program I can install that will allow me to get messages. I am running Android 4.0 and it is an unlocked GSM phone.
