Hi All sifus.... I just got my S4 LTE last week Friday... also just update the FW OTA. All is good.... I am curious, I have been roaming around to places with LTE coverage but my display has been showing H+ at most... I have not seen 4G yet on my phone.... The settings are right I presume... I called Maxis if I need to change my SIM to anything newer and they said no needed... do I need to change anything else, like APN...??? Thanks in advance
