No problem, my sister also lives in Italy and bought the iPhone SE in Switzerland.

I think the mobile can be put into operation wherever there is a matching SIM card. In the event of a warranty/repair claim, bring it in, i.e. send it to Galaxus. Make sure you have the proof of purchase with you in case any questions are asked at customs.

Hi, the appliance works very well. I would buy it in Italy. I don't know why, it's just my gut feeling.
