richms: I'm just annoyed as I assumed I was getting an unbranded note 3 and not a Vodafone one.
Is there a hidden menu to turn it on like there was on the s2 to turn off 2 when on a 2g/3g network?
It is not branded by VF.
When the phones came out Telecom was not on 4G/ Samsung did not have the operator details for Telecom to be a 4G provider. So all firmware which came with the phones did not support Telecom 4G. Since Vodafone was already a 4G provider all the firmware supported it. So if you have a note 3 with a VNZ firmware telecom sims will not work (4G) as the firmware does not have the required update on the other hand VF sims will work. Now the phones with the Telecom firmware also did not support 4G in the beginning until the last update which enabled the 4G for telecom sims. So until the VNZ firmware gets updates the telecom sims will not work on 4G.
If you want you can always flash the telecom firmware using ODIN on the VNZ one at your own risk.
PS: the VNZ firmware can be rooted without tripping knox. The latest updated firmware which telecom has recieved has an updated bootloader. No root
