No, UK was a big market but, Psion 5 was sold in a lot of other countries, they did loads of localised keyboards. I can remember looking at them in one of those electronics shop windows in Times Square NY, weighing up the pricing. PSion 7 and netbook were in there too.
Then Swedish Ericsson had the MC218 which was a badged Psion 5MX.
A lot of Gemini customers have mentioned being former Psion users in other countries.
