I have a UK P20 Pro and it didn't have a dual sim tray, just wondering if this is just a case of getting a dual tray and then it just working or something else needs to be done?

This was the same for the mate 10 pro.
You would need to get the European phone for the dual sim. This is not that clear and would only be confirmed by visiting a UK store and viewing the sim slot at launch but it always seems to be the single sim in the UK.
