P20 Use in US and Europe

I spend 5 months in Europe and 7 months in the US every year. Looking for one phone like the P20 Pro (that I could buy while in Europe). But I like to know if I can have both my US SIM (AT&T) as well as my Swedish SIM (Tele2 which by the way works all over EU) in the phone and receive and make calls on either phone number regardless if I'm in EU or US? I would like to receive calls and text on both phones and then I like to select which of my numbers (US or Swedish) I will use to call or text back from.
