Just got a S4 that's locked to 3 which is also running Android 4.3
I have tried this: [GUIDE] Galaxy S4 Sim-Unlocking - xda-developers, no joy as I fail at point 4 and do not get into the menu
I then tried this: how to access UMTS if you cant access UMTS menu on Galaxy s4 - xda-developers but this also did not work
Someone suggested the main problem is the phone is running 4.3
Baseband number: i9505xxuemk9
Any thoughts or help
