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?

Based on my work experience in the UK you need to make sure that when you ship it you declare as a temporary export for a warranty repair, and ensure that when it is shipped back to you it is declared as warranty return and that the relevant warranty repair documentation is included.

That's the answer to your question but not to your problem, unless the smartphone is valued at under 300CHF you should have officially exported it from Spain, then declared it when you entered Switzerland and paid the requisite duty and tax, and then at some point reclaimed the tax you paid on it in Spain.

The reality now is that you will probably get stung for duty and tax when it is returned unless you can prove that you have owned it for more than 6 months prior to moving to Switzerland, which is highly unlikely as the warranty paperwork will no doubt include purchase date.

Your best solution is to try and get it repaired through a manufacturers agent in Switzerland, warranties are usually international.

Not the answer you wanted but I believe what I have stated is correct there may be some here that know better.
