West European Version: What does buying a mobile phone mean?

I ordered a cell phone (Huawei mate 20 lite). It says that it is available in the "West European Version". What does that mean exactly?

That the model was not intended for the Eastern European market, but for Western Europe, which may then give some differences.
Other power plugs, possibly other bandwidths supported etc.

That it meets the product regulations of the Western European market.

This includes e.g. Also the power plug, frequency bands etc.

And in the case of Huawei spyware… Jk… Of course that's always on it.

This smartphone works only with frequencies that apply to Western Europe.
