So , I felt this was kind of interesting. I happened to get an Amazon echo for free that been in it's box for a year. Now I was renovating and had no dum radio /speakers / music available.

Ok lets try might be interesting at least.

Phone GOS no gapps , VPN .

Location EU country A. Both on VPN and irl.

Signup: Fake email , name address, detail and phone number.

Amazon echo extra permissions none, all privacy settings checked. Resettled ad id

Router , 4g teltonika using a sim card from EU country B.

Got it set up and set location to the next town over for local weather updates.

Set language to English / country A

Connected a new Spotify account also same setup fake number fake details.

Played some Spotify. Checked the weather all good.

Morning after l, moved it to a different outlet.

Spotify deactivated " service not available at your location" weather updates still have same town.

Ok lets check some radio , got it going.

Advertisement in country B language.

Curious how it's done. I did speak country B language a bit around it but seems weird to base it on that alone ( none recorded in that language according to history)
