If you shop tax-free as a non-EU resident, remember: you must take the goods out of the EU within 3 months and get your VAT refund document stamped by customs at your last point of exit from the EU (even if you bought the item in a different country).

112 is the common emergency number across the EU (it works from any phone, and operators can route you to the right service).

Roaming: in the EU/EEA, 'Roam Like at Home' usually means your plan works across member countries without extra roaming fees—but Schengen includes non-EU places (like Switzerland/Norway) where your operator may charge, so check your plan before you cross borders.
