My wife and I have used these e-sims in UK (England and Scotland), Ireland, Finland, Estonia, Latvia, Lithuania, Italy, Germany, Austria, Slovenia, and Croatia and have been pleased with performance. My wife did just have some connectivity issues in Slovenia and Croatia, but when I wrote esim.net support, they answered within an hour saying they did something to fix it and to just re-boot the phone. This fixed the problem. One important unusual thing to be aware of is that the 30 days starts immediately upon purchase so I typically buy them on day of departure from America, install immediately (still in America) and then it activates upon landing in UK or any European country. https://www.esim.net/o2/travelplus
