    Welcome to Android Central! Does it actually have 2 SIM slots?

    I have sourced a dual SIM bay holder (also can do SIM + MicroSD) so can now install two SIMs, it just only sees the one.
    Doing some research it seems installing G935FD firmware enables the second slot.
    any help appreciated.

    Doubt it's just the firmware.

    I'm keeping tabs on this to see if you get it working. Hybrid sim is built into quite a few Samsung phones but isn't usually activated here in the UK or Europe but the functionality is definitely there. I'd like to do the same for my SM-G950f s8

    You need the firmware for the UK for the dual-SIM phone, you need the dual-SIM holder - oh, yes, and you need the motherboard from the Dual-SIM model. That last one is probably the deal breaker. You can't just mount a dual-SIM holder into a single-SIM phone and use the second slot for anything other than an SD card.
