I'm considering buying a SM-G998U 'opened but unused' or 'reconditioned' to use in the UK. These are plenty of these available on amazon.co.uk and ebay all saying they work in the UK but I note that the spec shows that the 5G bands supported are different on the G998B & G998U but equally I've found no comment on the Web saying there is a problem.
I have also noted that the US spec S21 FE SM-G990U, which shares the same h/w with the G998U, supports the uk 5G bands.
This leads me to wonder if this is just a case of licencing or regulatory approval rather than a physical limitation.
I have read various opinions on this but wonder if anyone has actually used a G998U in the UK and can confirm if they got full 5G speeds
