eSIM use is rapidly expanding among travelers and business travelers visiting the United States.

In particular, the fact that you can easily open an eSIM account in the US with just a smartphone, without the hassle of purchasing or replacing an existing SIM card, is cited as a factor in its popularity.

In fact, there is a lot of active sharing of experiences and information about 'US ESIM opening' on search portals and online communities.

As major U.S. mobile carriers expanded their eSIM support this year, users of the latest smartphones can now activate a U.S. eSIM and immediately use local telecommunications services without a separate physical SIM card.

In the past, you had to overcome language barriers at the airport or in stores, but now you can conveniently choose a data plan and open a US ESIM online before departure, maximizing convenience.

In particular, the representative advantages of opening an eSIM account in the US include: △no need to purchase or replace a SIM card overseas, △data use possible immediately upon arrival in the country, △easy switching between rate plans of various carriers, and △simultaneous use of Korean and US numbers on one smartphone.

Recent eSIM users in the U.S. are unanimous in saying, “You can complete activation with just a few settings on your smartphone without having to visit a local carrier store,” and “It saves a lot of time and money when traveling or on business trips.”

Experts advise, “Before opening an eSIM account in the US, it is important to check device and carrier compatibility in advance and compare and choose the plan that is right for you.”

Travelers and long-term residents visiting the United States are expected to increasingly utilize non-face-to-face opening services like US ESIM.
