First off all, this is my first post, and I hope it's in the right place!
Two weeks ago I bought a smartphone in my home country (Spain). Unfortunately, when I came back to Switzerland, the mobile phone started to have problems with the phone network - I think the antenna is is faulty, but that's not the topic.
I had to send the phone through the borders for technical assistance, and my parents then will send me the mobile phone back when I've the new one.
The thing is I am a bit worried about if they can stop the phone in the border (for taxes or something like that). I paid the VAT in Spain so I don't know how works in this case.
Can someone illustrate me about how works?
Should I include the bill?
