Hi @SharpSwitch. The reason you are unable to update your phone's software is because your device was originally manufactured in the United States.
As such, in order for it to receive updates through the conventional method (i.e. Settings > Software update > Download and install) you would need to use a SIM card that is intended for use within the US. If you have such a card, please insert it into your phone and try to update it as normal.
If you are not able to use a US SIM then not to worry, it is possible to download phone updates manually by using our Smart Switch service. To do this, you will need to download this service onto a computer. You can find the relevant links for doing this under the section titled "Download now" via https://www.samsung.com/uk/support/switching/
Once you have downloaded Smart Switch to a computer, please follow the steps below:
> Connect your phone to your computer using a USB cable, and then open Smart Switch on your computer.
> If a software update is available, Smart Switch will automatically prompt you to download this.
> Click "Update", and use the on-screen prompts to download the necessary files.
> Click "OK" to proceed. Your phone may turn off and on a few times during the update process.
When the update is complete, the phone will boot as normal.
