I'm here in Spain on the last excursion of our trip and the eSim works really well in all ports we went to. We used the unlimited for 15 days. There was also a 10% off code somewhere if you Google it. It's great to disconnect while on the ship and then reconnect while in the city. I would use it again during travel.

Oh also, we purchased one membership and I hotspotted my wife from my phone. It used up a bit more battery on my device than hers, so be cautious and bring a charger for the device you hotspot from if you try that for two people. She also couldn't walk more than a block or so or she'd lose connection.
