That is something to consider, but China and EU bands in particular are very similar, and I for one have experienced no difference whatsoever in carrier compatibility vs an EU model, this isn't the first device I've imported either. For a bigger picture I have 2 SIM Only plans from different carriers in the UK, 1 from EE and 1 from Vodafone. Everything works as it should, including LTE, 5G, Vokte and WiFi calling. I'll include a screenshot of the status bar of my OnePlus 10 Pro with the EE SIM card inside, and I'm indoors.
