For years, I did what most American travelers do: I called my carrier before a trip, added an international plan, and hoped it wouldn’t cost too much. On my trip to Austria, Germany, and Switzerland last year, that meant going with AT&T, which charged me $12 per day for throttled data, spotty coverage, and anxiety.

Before I arrived in Munich, I started researching the available providers. A few things matter most when you start evaluating your eSIM options, regardless of where you’ll travel.
