Check whether your bank card or home insurance already covers this trip.
If the trip needs a visa, the travel agent or visa centre usually sells the cover it asks for.
Mobile data (eSIM)
Your own plan's EU roaming may already cover this.
Renting a pocket Wi-Fi is the other common way to stay connected.
These are sites people in book with. Each opens in a new tab, on the site's own pages.
