Using an eSIM when I traveled through Europe made things so much easier. I just scanned a QR code, and boom—data and calls were set up right away. Gladly now we have phones that work w/o a physical sim inserted. So, if you’re looking for something similar, you might want to check out https://simsdirect.com.au/collections/europe; they’ve got options that cover a bunch of countries, so no SIM swapping every time you cross a border.
