When should I buy an eSIM before embarking on my travels? Is it prudent to procure one prior to my departure, allowing for immediate connectivity upon landing in a foreign country? Or should I consider acquiring it after I arrive, perhaps to explore regional options that may offer enhanced benefits or attractiveness in pricing? What are the potential implications of each choice? If I choose to buy an eSIM before my trip, will I have access to technical support or customer service from the provider if unforeseen issues arise during my travel? Conversely, if I opt to delay my purchase until after I reach my destination, will I risk being without essential mobile data during my initial moments in a new locale? Moreover, how do factors like my travel itinerary, data requirements, and the reliability of service providers weigh into this decision-making process? What recommendations do seasoned travelers have regarding this conundrum?
