Hi I have a samsung s9+ which was purchased outright from JB Hifi. Phone seems to be functioning properly. The Sim only plan works but I am unable to send mms. I have checked all the APN settings on the phone and it still fails. I have tested the sim in an Samsung s5 and it works. I have tested another TPG sim which works in the s5 but also fails to send mms in the s9+ Data is on. Is there any other settings I need to review?   thanks Rick ... View more
